Changelog Archive | Track Impulse

Fixed

fix Updating from inside the app now runs straight through Accepting an update from inside the app could pause the installer on an "Error opening file for writing" message. The installer now handles that file correctly and the update completes without stopping.

Fixed

fix Overlays-only install couldn't start Installing only the Overlays component (without the main haptics app) left the overlay unable to launch. A file both apps need is now always installed, so the overlays start on their own.

Fixed

fix Le Mans Ultimate: lap times were saved against the wrong lap In Performance Review, every Le Mans Ultimate lap was stored under the following lap's time. The lap list, the session best and the coach could all disagree, and the coach would report several seconds of lost time on a lap the list showed as a tenth off. Laps you drive from now on are recorded correctly. Le Mans Ultimate sessions saved before this fix have been removed, because there was no reliable way to tell which of their times were wrong, and Performance Review explains this once the next time you open it. iRacing was never affected and its saved sessions are untouched.

fix Performance overlay: Sprint timers no longer run into each other On the Sprint panel the left-hand time was printed hard up against the label beside it, so a row read as "0.034 0-100 kph" with the digits touching the next word. The two columns now have a clear gap between them. The green PB tag on the bottom row also sat on top of the "0-60" label instead of beside it. Both looks of the Performance overlay are fixed.

New

new Two rally games added: DiRT Rally 2.0 and EA Sports WRC Pick either from the sim list for suspension, engine, gear, wheel lock and wheel slip through your shakers on a rally stage. Both need their telemetry switched on in a settings file first, so Track Impulse shows you the exact file, tells you what is missing, and offers to make the change for you.

new rFactor 2 support Pick rFactor 2 from the sim list for the full set of effects: road texture, suspension, kerbs, engine, wheel slip, gear changes and wheel lock, with the same automatic per-car and per-track calibration the other sims get. The overlays work too. Marked Experimental while we gather feedback.

new Guided setup for the rFactor 2 add-on rFactor 2 sends nothing until you add a small free plugin and tick it in the launcher. Track Impulse finds your install and walks you through whichever step is still outstanding.

new Rally overlays: dashboard, shift light, inputs and the haptics HUD Both rally games. Panels built around racing other cars stay hidden on a stage, where there is nothing for them to show.

new Performance Review now works in Le Mans Ultimate Your laps are saved per car and track, reviewed and coached after the stint, and can be shared to or downloaded from the community boards. The two sims stay separate, each with its own history, and a picker in the title bar chooses which game's laps you are looking at.

new The Live Coach now works in Le Mans Ultimate The full coach, the same as in iRacing: a tip after each lap, a prompt as you arrive at the corner costing you time, the braking bar, the corner strip and the end of stint summary. Most circuits are coached by turn name and number, and the coach learns exactly where each corner is from your own laps.

new The Line view draws Le Mans Ultimate's real road Drawn on the actual track at true size with real road edges, taken from the game rather than guessed, so your line and another driver's line up straight away.

new Le Mans Ultimate: brake bias, traction control and ABS on the dash All three read live and change as you change them in the car.

new Put any shortcut on a wheel button Every shortcut in both apps can now be a button on your wheel or button box instead of a key, or as well as one. Mute the haptics, switch profile, hide an overlay or commit a pit strategy without taking your hands off the wheel. It also sidesteps another program having already claimed the key combination you wanted.

new The coach can talk to you now The Live Coach reads its tips out loud, so you can take the advice without looking away from the road. The spotter always has right of way, and a tip that would land after the corner is dropped rather than said late.

new The coach counts the time it finds you A running total of the time you have found in that car at that track since coaching started. It never resets and it can only rise.

new A braking point you can feel Feel your reference lap's braking point as a pulse through your shakers, hear it as a tone, or both.

new Four new things to read at a glance while you drive A bar under the coach chip counting down to the braking point, your brake and throttle beside the reference lap's at the same spot on track, a mini-map that goes green as you master each corner, and a panel showing the lap you are chasing against the lap you are on for.

new Get coached against the community's best lap The coach now compares you against the fastest community lap for your car and track by default, and falls back to your own best when that is faster or there is none.

new Your new personal best gets celebrated The coach chip turns green with the new time and how much you took off.

new The coach says your new best lap time out loud Cross the line on a personal best and you hear the time itself, not only that you set one, so your eyes stay on the road.

new A recap card when your stint ends One card as you pit: the time you found, your best lap, and the one thing to work on next time out.

new A chime for the sectors you beat A short rising tone for a sector you beat, a lower one for a sector you did not. Off by default.

new A guide for a track you have never driven The coach talks you round, naming each corner and telling you where to brake, then steps aside once it has enough to coach your own driving instead. In Le Mans Ultimate it can do this from your very first lap; in iRacing it needs a reference lap, so download one from the Community tab first.

new Performance Review shows what the coach has done for you The Coach tab names the lap you are compared against, how much time is still on the table, and the corners you have fixed.

new See the reference lap's pedals while you drive The Delta Trace overlay can show the brake, throttle and gear your reference lap used at the piece of track you are on. iRacing only.

new The spotter tells you a car is still alongside It now repeats "still left" or "still right" while they stay with you, instead of calling once and going quiet.

new Pit strategy settings where you actually use them The pit strategy switch and its shortcuts now also sit on the Fuel overlay's own settings, not only in app settings.

new Find and save overlay profiles without hunting through the list The profile menu now has Sim and Car filters at the top, so a long list narrows to what you want. Clicking a row no longer loads it straight away: it grows a Load and a Save button, so a stray click can no longer replace the layout you are using, and saving over another profile asks first. Profiles pick up the sim and car you were driving each time you save.

new Put your overlays straight into OBS as Browser Sources Add any overlay to OBS as a Browser Source and it arrives with proper transparency: no grey box behind it, no background colour to key out, and no need to keep the window uncovered. Track Impulse gives you the address for each overlay you want on stream and you paste it into OBS. Nothing leaves your own machine: the overlays run a small web server on your own PC, and it only ever answers that PC, never anything else on your network. Each address also carries a one-off key that changes every time you start the overlays.

new The overlays offer your saved profile when you change car Swap to a car you already have a profile for and the overlays ask whether to load it. They never switch on their own.

new The Live Coach starts talking straight away at a track you have driven before Back out in the same car at the same track, in similar temperatures, and the coach picks up from that session instead of watching you for three laps. Today's laps take over as you drive. A big temperature swing, or dry to wet, starts it fresh.

Fixed

fix The Live Coach now shows what it is waiting for While it gathers your first three laps it now says the coach is watching, with a percentage that climbs as you drive. If a lap did not count it says why underneath: traffic, an invalid lap, an out or in lap, or a lap too far off your pace to be useful.

fix The Live Coach no longer starts over after a trip to the garage A visit to the garage threw away the laps the coach had already counted. They now survive, and are only let go when you change car or track.

fix The Live Coach counts more of your practice laps A faster car going past on a straight used to count against a lap the same as being stuck behind someone through a corner, which on shorter circuits rejected most of a practice session. Only traffic that actually costs you time counts now.

fix The Live Coach stays active on very long stints The coach went quiet after 100 laps in a single session. It now keeps going however long the stint runs.

fix Your stint is saved even if you quit the game from the car Closing the sim without going back to the garage first now saves that stint too.

fix Opening a community lap from another car and track could close the overlay app Open combo board and Download and compare are both solid now, whichever lap you pick.

fix Sharing a lap now tells you why it was turned down It used to blame the connection whatever the reason, even when the server had answered and explained the problem.

fix "Restore your last settings?" asked when you had not changed sim The overlays offered to restore an older layout on every start, and accepting it replaced the setup you were happily using. It now only asks when you have actually switched sim, and tells you what would change before you answer.

fix Sim and Car boxes floating over the settings pages The two filter boxes from the profiles page stayed on screen after you left it, drawn on top of whatever settings page you opened next.

fix Suspension now works on iRacing cars that had none, such as the Street Stock A handful of iRacing cars describe their suspension differently, and those cars sent no suspension feedback at all. If a car was affected the effect simply starts working, at full detail, with nothing to change and no need to recalibrate.

fix Audio now recovers on its own after a sound device drops out If your sound device stopped responding, changing devices or backing out of the device setup could leave the shakers silent while everything still reported as working. Output now restores itself within a couple of seconds, and keeps retrying instead of waiting for a restart.

fix "Personal best" alerts fired for laps that were not personal bests The alert only looked at the laps in that session, so any quick lap on a fresh start was announced as a best. It now checks your genuine best for that car and track, clean laps only.

fix Assetto Corsa EVO buzzed through the whole loading screen The shakers droned for the entire time a track was loading. It now stays quiet until you actually have the car, and starting the engine still comes through in full.

fix Switching an effect off now stops it on Simagic pedals too Turning off ABS, Wheel Slip, Engine or Gear silenced the shakers but left the pedals buzzing. Turning pedal haptics off now also stops a pedal caught mid-buzz.

fix Mute and window changes now stop a held Test button Holding an effect's Test button and switching to another window left that effect running at full strength, and mute did not silence a zone or effect test.

fix A phantom bump when restarting in Assetto Corsa and AC Rally Restarting a session or coming back from a pause could deliver one hard hit before you had moved.

fix The shakers could stop updating in F1 If something else on your network was busy on the same port F1 uses, feedback stopped coming through. Track Impulse now handles the clash.

fix The Community list did not keep up with sharing and unsharing A lap you had just shared was missing from the Community tab, and one you had just unshared was still in it, until you pressed Refresh. The list now updates itself.

fix Your chosen profile is remembered for every sim Only the first ten sims were remembered; any sim after that fell back to the default profile on every launch.

fix Opening the overlay settings no longer switches Demo mode on It used to turn Demo mode on by itself, filling your screen with made-up data, with no way to switch it off from that window.

fix Overlay settings named the wrong sims Several overlays claimed to support fewer sims than they do, so you could have skipped one that would have worked for you.

Improvements

impr Track Impulse is now a registered company Track Impulse is now run by Track Impulse Pty Ltd, ABN 94 701 391 764, which is named in the licence agreement and the installer. Nothing about your licence, your settings or your files changes.

impr Mirror windows are lighter on your PC An open mirror window used to redraw thirty times a second even when the overlay it was showing had not changed. It now redraws only when there is something new to show, which for a panel like Fuel is a fraction as often. Nothing looks different, it just costs less while you stream.

impr Custom corner mixes now hold their volume at any dial position Turning a zone's Customise dials part-way down used to quieten the whole zone as well as change the balance. The dials now set the blend and the zone's volume slider sets the level, so if you run dials part-way, that zone will come back a touch louder after this update.

impr New installs start with a ready-to-race overlay setup Track Impulse Overlays now starts with seven panels already on and styled: Dash, Battle Bar, Relative, Standings, Shift Light, Spotter and Coach, each centred so you can drag them where you like. If you already use Overlays, your own setup is untouched.

impr Clearer spotter and alert voices Every line in both voices, Michael and Sarah, has been recorded again from scratch. All of it is clean and even now, at a consistent level.

impr A clearer way to get your overlays into OBS The Stream Canvas has been replaced by adding each overlay to OBS as its own source, so you can position and resize each one with OBS's own tools. Use a Browser Source for the cleanest result, or capture the mirror window if you prefer. The Stream section of App Settings walks you through both, including the one OBS setting that catches people out.

impr Spoken alerts no longer louder than the spotter Both are matched now, so one volume setting works for everything.

impr Keep the coach on screen as long as you like Choose how long a tip holds, keep the last one on screen between tips, or have it fade out gently.

impr The main app is now called Track Impulse Haptics Matching the companion window, which has always said Track Impulse Overlays. With both open, the taskbar tells you which is which.

New

new A coach that watches your laps and tells you where the time is A new Live Coach overlay compares your recent clean laps against your personal best in that car at that track and gives you one short prompt at a time: brake later, get to power sooner, use all the exit road. It names the corner costing you the most, the number to aim for, and what fixing it is worth. It picks its moments, staying quiet when you are wheel to wheel, under yellow or in the pits. You choose what it may call out and how often. iRacing only for now.

new Pop-up alerts for the moments that matter A new Alerts overlay puts a small card on screen for a few seconds when something happens, then gets out of the way: a personal best, a fuel warning, and every flag from yellow and blue to the meatball. Alerts can be spoken out loud as well, in the same voices as the spotter, with three different takes of every line so a long race does not sound like a recording on repeat. The voice is off until you turn it on, and the spotter always has right of way.

new Your pit strategy, worked out for you The fuel overlay can now show your stop options: no stop and save a little, one stop on lap 14 with 34 litres, two stops, and roughly what each one costs you overall. No sim publishes what a pit stop actually costs you, so Track Impulse times it for your track and car. Press Alt+F8 to cycle the options, and it flags a genuinely better plan when one appears.

new Set your iRacing pit fuel with one key Off by default, and worth reading before you switch it on. With it enabled, pressing Alt+F9 puts the selected strategy's fuel figure into your iRacing pit box so you do not have to type it in mid-race. It only ever sets fuel: your tyre, windscreen and fast repair choices are never touched. It acts only when you press the key, never on its own, and only while you are in the car. iRacing only.

new Fuel saving, with somewhere to actually find it When your strategy needs you to save fuel, the fuel overlay tells you how much per lap, whether the lap you just finished hit it, and how far ahead or behind the plan you are. On iRacing it goes further and names the corners where lifting early costs you the least time.

new Browse every shared lap on the Community tab The Community tab now opens on every lap the community has shared rather than a single board, grouped by track and filterable by car. Select any lap for its sectors set against your own best, the conditions it was set in, and a Download and compare button. You get the track outline even for circuits you have never driven.

new Shared laps now carry the detail behind the time A shared lap takes its sectors, top speed, temperatures, wetness, driver aids and tyre compound with it. Nothing is invented: anything your session did not record is left out.

new A guided tour of Performance Review The first time you open Performance Review it shows you around, highlighting each control as it goes. Replay it any time with the Guide button.

new American Truck Simulator is now detected automatically Starting American Truck switches Track Impulse over for you, to the ETS2 setting, which is the correct one for both trucking games.

new A real flag on your dash A new flag element for any square dash slot or as its own widget, drawing the actual flag rather than a coloured box.

new Watch your best lap back with one click After an iRacing race, Race Recap gains Watch best lap, and Prev and Next incident buttons that step through iRacing's incident list.

new Projected lap time, wherever you want it A new field showing where your current lap is heading, plus a Best Lap field, in any overlay slot.

new The Battle Bar tells you how many laps until you catch them Each car ahead and behind carries a short read on the fight: catch in four laps, or safe and pulling away. It says nothing rather than guessing when the trend is too noisy to trust.

new The Battle Bar can cycle your lap time Rotate your time between last, projected and best, with a label and your choice of dwell time.

new Time, fuel and incidents turn amber and red as they run out Every threshold is yours to set, and zero turns that warning off. The fuel overlay also flashes when a lap costs more fuel than usual.

new A consistency meter for your last few laps A bar that shrinks as you get more consistent, one dot per lap. Pit laps and big offs are left out.

new Optimal lap and positions gained as data fields

new See who is on fresher tyres A Tyre age column on Relative and Standings, as a lap count or as New, OK and Old. iRacing only.

Fixed

fix The on-screen steering wheel now matches your real one, on every sim Several sims never say how far your wheel turns, so Track Impulse now asks you once for the Rotation setting you use in the game and remembers it per car. Tick "use this for every car" and you will never be asked again. ACC fills the figure in for you, BeamNG never asks, and if the wheel on screen still does not match your hands, the Calibrate button measures it directly: hold your wheel at a half turn, press S, done.

fix Euro Truck and American Truck kept dropping in and out while you sat in the menus

fix The clutch and gear readouts were wrong in ACC

fix Assetto Corsa EVO no longer shakes violently while a track loads This also quiets the shake after a tow or a reset back to the pits.

fix The last sector of every lap was missing from Performance Review

fix Some overlay settings pickers were missing options

fix An invalid lap could still be shared A lap spent stuck in traffic is no longer offered to the community board either. Laps you shared before this update stay where they are, and you can still take any of them down yourself.

fix You can get back to the track map after opening a coaching point A new Map / Telemetry switch on the Coach tab.

fix The profile bar now always shows which sim your layout belongs to

fix Your own class now shows its name and strength of field on the Standings overlay

Improvements

impr The corner dials on a custom zone now set balance, not volume The four dials on a customised zone now always add up to the same total, so they decide where that zone's signal comes from rather than how loud it is. If you had pulled some of them part way down, that zone will come through stronger than before: set the level you want on its knob under Zone Volumes.

impr The fastest lap in the field is always purple, and your own best is always findable Purple now marks the fastest lap at all times, in every style, with your own best in cyan when somebody else holds it. Every class gets its own purple in multiclass.

impr Every overlay setting now explains itself Each switch, slider and picker carries a short line saying what it does.

impr The fuel overlay now tells you how much fuel a lap costs Per-lap fuel use now sits under the tank reading on every layout, from your first clean lap.

impr The restore prompt only appears when it has something to restore

impr Closing the overlays app now saves the settings you close it with

impr The save button on the profile bar shows you it worked

impr The Battle Bar shows full driver names, with a bigger car manufacturer badge

impr The zone setup guide explains the corner dials

New

new Radar and spotter overlays now work in Assetto Corsa EVO The Radar/Spotter overlay tracks every car around you in AC EVO, showing true range and side, not just left or right. Set your own range, pick bars, radar or disc style, and place it anywhere. Car numbers stay blank because AC EVO does not share driver identity.

new The driving coach spots three more ways you lose time Performance Review now calls out braking softer than your reference, reaching full throttle late out of a corner, and picking up throttle too early so the corner tightens on you. It also flags when your throttle pedal never reaches 100 percent, usually a sign the pedal needs recalibrating.

new Assignable hotkeys that work while you are driving Settings, then Shortcuts and Tips, now lets you bind any key combination to mute, volume up and down, next and previous profile, show and hide the window, and each effect on or off. They work with the sim in front, so you can adjust without leaving the car. Nothing is assigned to begin with, and the box turns red if another program already owns that combination.

new Text size option in Performance Review The Options menu now has a Text size setting (100%, 110%, 120%) for easier reading on 4K screens or from further away.

Fixed

fix AC EVO no longer shakes violently while a track loads The shakers used to fire at full strength for about a second while the loading screen was still up, just before you got the car. That jolt is gone, and the same fix also quiets the shake after a tow or a reset back to the pits.

fix AC EVO no longer drops to the desktop from the menus Sitting in AC EVO's menus with Track Impulse running could throw the game out to the desktop. Driving was never affected, and the game now stays put. AC EVO only sends data once you are on track, so the connection light coming on as you head out is normal.

fix The radar now warns you whenever a car is actually beside you It used to only light the red warning when the two cars were almost exactly level, so a car overlapping you by half its length could sit there showing nothing but an amber dot. The warning now comes up any time your cars overlap and they are close enough that moving over would hit them, sized to the car you are driving, so a small hatchback and a prototype each get the right amount of room. Affects Le Mans Ultimate and Automobilista 2.

fix F1 and BeamNG now work with the overlays and the main app open together Whichever you started first used to claim the game's telemetry and leave the other with nothing. Track Impulse now always gets it first and the overlays read it from there, in whichever order you start them.

fix Battle Bar text no longer runs underneath the gap times On the Apex Battle Bar, the car label under a driver's name could stretch behind the big gap number and make it hard to read. Nothing in that line can reach the gap times any more.

fix Performance Review text no longer gets cut off at larger text sizes With Text size set to 110% or 120%, the labels on the graphs (SPEED, BRAKE / THROTTLE, STEERING, DELTA) were sliced off across the bottom, and the trail braking numbers under a corner ran into the note below them. Everything now has room to draw in full, at any text size and any window size.

fix Performance Review now scales correctly on every display Text used to open too small on scaled Windows displays and stop growing before the window did when stretched or maximized on a large screen. Both now track your screen properly.

fix Performance Review, the dash layout editor, Fuel and several dialogs are now fully translated These kept showing English text in places whichever language you picked. They now follow your language setting throughout.

fix Update notices no longer interrupt you mid session The update notice could appear while you were driving and pull the game to the desktop. It now waits until you are out of the car.

fix Broken download buttons on the older versions page Some versions on the website's older versions page had a download button that led nowhere. Every listed version now downloads correctly.

Improvements

impr Clearer coaching advice Coasting advice now says how to close the gap, whether that is carrying the brake deeper or picking the throttle up sooner, and the throttle stab advice now notes that a touch less entry speed is often the real fix.

impr The radar flashes a red warning down the side a car is on The radar style used to only change the other car's marker colour. It now also lights a pulsing red glow along that edge of the panel, matching the disc style.

impr Manufacturer badges on the Apex Battle Bar Both drivers on the Battle Bar now show their car's manufacturer badge next to their number and licence, so you can tell at a glance what you are racing.

New

new Rebuilt first-run setup wizard Setup now asks for your sound cards first, and everything after is measured against what you actually have. Five steps instead of seven, up to four sound cards, with your total channel budget shown as you go. Any shaker layout your outputs can't feed is greyed out with the reason, and finishing the wizard offers to walk you straight into the Zone Setup guide.

new Shakers on a second sound card now work Each shaker is assigned to its own card and channel, hold-to-test plays through the right card, and the wizard routes everything correctly. Setups that used to leave a second card switched on but silent now work as expected.

new The Performance Review coach now coaches your whole stint Instead of comparing one lap against one other lap, the coach looks at every clean lap of your stint and names the habit that's costing you time, backed by how many laps show it. Findings give you a target and say what fixing it is worth in seconds.

new The coach understands corners the way drivers do Chicanes and runs of esses are treated as one corner with one piece of advice, not several conflicting ones, and coaching now works on every track, including ones without a numbered corner list.

new Trail braking analysis The coach now reads how you release the brake into a corner: how much you carry to the apex, how you ease it off, and how much of the tyre's grip you're actually using, with findings on when to hold, when your release is unsettling the car, and how much grip is still on the table.

new Corner detail view Click a finding and the map zooms to a close-up of that corner, showing your typical line with a variance band laid over the reference on speed, pedals and steering, plus a side-by-side trail braking comparison against a community lap.

new Fair coaching references By default the coach measures you against the best clean lap of the same stint. Laps stuck behind traffic, out laps, in laps and invalid laps are excluded from the analysis, and the coach always tells you how many were excluded and why.

new A consistency check that knows when it matters When your typical lap is well off your own best, the coach flags it first, names the corner where you vary the most, and reminds you that repeating your good laps is worth more than chasing new speed. It stays quiet on a consistent stint.

new Performance Review has its own button in the overlay top bar One click away wherever you are in the overlay window, and it lights up while the Performance Review window is open. On a narrow window the button shrinks to its icon, so it never crowds the rest of the bar.

new Low profile version of the Apex dash A shallower take on the Apex dash cluster, about 40% shorter than the standard version, with the same widgets, layout editor and settings, so it fits under a wheel or along the bottom of an ultrawide without covering the road.

new Switch off the parts of the dash you don't want The battle bar, the info strip and the rev counter each have a switch in the Dash Layout editor. Anything you switch off is removed rather than left blank, and the dash shrinks to fit so there's never an empty gap.

Fixed

fix Advanced Device Setup now remembers the right sound card between sessions It used to find your saved sound cards by their position in the audio device list, which can shift between sessions. It now recognises each card by what it actually is, so your saved selection comes back correctly every time.

fix Unsharing an already-removed community lap no longer gets stuck If your shared lap had already been taken off the community board, for example by moderation, it stayed marked as shared on your machine and couldn't be shared again. It now clears properly.

fix Community lap comparisons no longer show impossible time differences A lap shared by an older version could carry data that didn't match its lap time, which made comparisons against it show huge phantom losses around the start/finish line. Those laps are now refused with a clear message, and start/finish comparisons are more accurate for everyone.

fix The overlay Demo button no longer disappears on a narrow window Shrinking the overlay control panel used to make the Demo button vanish entirely, so there was no way to tell demo mode was still on or to turn it off. It now shrinks to a small icon instead, staying visible and clickable at any window size.

fix Le Mans Ultimate now gives feedback while stationary, not just moving Sitting in the box with the engine running used to give you nothing until you pulled away: no engine rumble, no meters moving. Track Impulse now treats being in the car as being on track, so revving on the spot comes through the way it does in every other sim.

fix ABS no longer buzzes on clean stops in Assetto Corsa The effect leaned on a reading that sits high even when you're just cruising, so it fired on almost every stop. It now works out how much each wheel is sliding, learns what hard braking normally feels like in your car, and speaks only when ABS is genuinely working.

fix Long release notes no longer cut off mid-sentence Bigger releases had their What's New notes stop partway through, so everything after that point was never visible. The full notes now show, however long they are.

Improvements

impr Advanced Device Setup shows your channel budget up front The device page adds up the output channels across your selected sound cards and shows the total with a per-card breakdown, right where you pick them. Picking the same sound card in two slots is flagged on the spot with the reason.

impr Zone Setup Guide now covers Channel Routing too A third page joins the guide, matching the one on the website: the Channel Routing screen tuning the five shaker rig from the previous page, with a control reference alongside covering drag, right-click to mute, scroll for 1% steps, double-click to reset and more.

impr Performance Review opens at a more useful size The window now opens large enough for the side-by-side analysis views, instead of a small default that almost everyone resized immediately. On smaller screens it still fits within the desktop.

impr Smoother and more accurate overlay data in iRacing The overlays now pick up every update iRacing publishes instead of roughly half of them, so timing, gaps and recorded laps are noticeably smoother and more precise. Lap records also now remember the fuel load, tyre age, weather and driving aids each lap was driven with.

impr Roomier Apex dash widgets The small caption above each widget on the Apex dash is gone. Every widget now uses the full height of its slot, so the pedals, inputs trace and g-force meter have more room and read more clearly at a glance.

New

new Community tab in Performance Review Browse every shared lap for your car and track, compare against your best, preview its line and load it for comparison. Replaces the Best Lap Trend tab.

new Your driving helps build better track maps for everyone With community lap sharing on, your laps now also share anonymous track geometry, so tracks get more accurate driving lines and a community line in Performance Review's Line view as more drivers contribute.

new Keep sight of your real rival while lapping traffic The Battle Bar's Apex layout adds a second line naming your true rival and the real gap to them whenever a slower car is between you, tagging the car in front or behind with its class or laps down.

new See where the time is going in a battle With no car in the way, that line shows time gained or lost to the drivers ahead and behind over your last lap and last few laps.

Fixed

fix Blank boxes on the dash where TC, ABS or brake bias should be These now read "N/A" when your sim has no such reading, and "None" on TC/ABS cells for cars that have neither system.

fix Standings was empty at the start of iRacing qualifying Every driver now lists from the moment you join, with correct class colours and a dash where an unset time or position would go.

fix The track map hid cars in iRacing practice and qualifying Every car in the session is now drawn, whether or not it has set a time.

fix Your position and strength of field were missing before the green flag Both now show from the moment you are in the session, and strength of field holds steady in qualifying instead of climbing.

fix Car numbers lost their leading zeros in iRacing Car 01 now shows as 01 and 007 as 007, everywhere a car number appears.

fix Community lap downloads could fail until you refreshed the list by hand Expired download links are now renewed automatically when you pick a lap.

fix Lap times in Performance Review were paired with the wrong lap's driving data Each lap now keeps its own time paired with its own driving data, in the analysis views and in shared laps.

fix Community lap lines draw again on tracks still gathering data The Line view now draws a community lap right away, marked approximate, and upgrades it automatically once enough drivers' data agrees.

fix Gaps to the cars around you are now precise and consistent Battle Bar, Relative's INT column, dashboard battle strips and the Twitch !gap command now show true, consistent gaps from the green flag, including across the start/finish line, through the pits and between classes.

fix More reliable track maps and driving lines Track maps now stay sharp and true to the circuit, with the pit lane kept separate from the racing surface, and the driving line lines up on every track.

fix Positions did not update until you crossed the start/finish line in iRacing Positions, class positions and the class-leader gap now update the moment a pass happens, matching every other sim. Pace lap, post-finish, practice and qualifying still follow iRacing's own order.

fix The spotter showed ghost cars in iRacing qualifying The spotter now stays off during qualifying, when the field is hidden but still on track. A "Show in qualifying" switch brings it back for open qualifying.

fix Spotter voice callouts weren't playing Voice callouts now work, and all three voices are levelled to the same volume.

fix Missed "clear" callouts from the spotter A car called on one side no longer skips the "all clear" or the next car on that side.

fix The licence field on Relative and Standings showed the wrong thing All three display choices now show the right value, and the text is coloured by licence class.

Improvements

impr The Battle Bar now watches every car class by default It used to stay silent about a car from another class right on your bumper. A new Cars setting brings back own-class-only if you prefer it.

impr The community leaderboard shows the whole board Up to 20 shared laps per car and track are now listed, instead of only the top five.

impr Reporting a community lap moved out of the leaderboard The report action now lives in the Options menu and only appears with a lap selected, so it can't be clicked by accident.

impr The main window can now be made much smaller The top toolbar now adapts as you shrink the window, down to less than half its old minimum width.

impr Slimmer profile and sim selectors The top bar's selector boxes are now compact icon buttons, and the profile menu holds all profile actions in one place.

impr Voice callouts land sooner, and you can test them Callouts now trigger closer to the moment a car comes alongside, and a Test button checks your voice pack and output device.

impr Sharper track maps, especially on the long circuits Built-in track maps now use up to twice the detail, most noticeable on long layouts.

impr A tidier overlays settings screen Leftover Reset pos, Demo and Layout buttons are gone from the settings screen; Demo and Layout remain on the overlays list.

Fixed

fix Performance Review now opens in front Opening Performance Review from the overlays list sometimes left it stranded behind the overlays window, so it looked like the click had done nothing.

fix The overlays window stayed on top after an update prompt Once the overlays app had shown you an update prompt and you closed it, the overlays window stayed pinned above everything else for the rest of the session, even with "Always on top" switched off.

New

new Performance Review is finished (iRacing) It has carried an experimental label since it first appeared. It is now a finished part of the app. Every lap you drive is recorded in the background, and the Coach tab ranks the corners costing you the most time and says why in plain English: coasting on entry, back to full throttle later, braking earlier, apex speed down. Compare against your personal best, your last lap, any lap you pick, or the community best for that car and track. Included and unlocked, with a switch to stop it recording anything if you would rather it did not.

new F1 25 support Track Impulse now drives your shakers from F1 25: road texture, suspension impacts, kerbs, engine rumble with its rev limiter, ABS, gear changes and wheel slip, with nothing extra to install, and the suspension effect learns each car as you drive it. F1 sends nothing until telemetry is switched on inside the game, so picking F1 25 brings up a short checklist of what to change, including the update rate the game sets far too low for haptics. The checklist comes back if nothing has arrived after twenty seconds.

new Feel the engine start Turning the key now comes through the shakers: the starter labouring against compression, the thump as the engine catches, and the flare settling down to idle. It has its own volume, separate from engine rumble, so the start still lands hard with rumble dialled right down, and you can turn it off in the engine effect's advanced settings. Working in iRacing, ACC, Le Mans Ultimate, AC EVO, AC Rally, AMS2, BeamNG.drive and Euro Truck Simulator 2. BeamNG needs one restart of the game after updating.

new Euro Truck Simulator 2 is no longer experimental Road texture, suspension, engine rumble, gear changes and wheel slip now all work the way they do on every other sim, along with the engine gauges, fuel readout and G-force display, and the effects fall silent when you pause the game. If you tried ETS2 before and gave up on it, it is worth another drive.

new Relative and Standings for Assetto Corsa Competizione ACC does not share the rest of the field the way other sims do, so these two overlays could only ever show your own row. They now fill properly, with driver names, positions, gaps and lap times, once ACC's broadcasting settings are switched on (a one-off change in ACC's own config file).

new Spotter now works in ACC and AC EVO The proximity spotter and its radar now cover ACC and AC EVO, tracking the cars around you the same way they do on every other sim.

new The phone companion is back Companion turns your phone into a remote for Track Impulse: change master volume, effect levels and zone gains, switch profiles and watch what is firing live, without alt tabbing out of the game. Switch it on from the new Companion button in the toolbar and scan the code with your phone. Only a phone that scanned it can connect, a fresh code is issued every launch, and your phone needs to be on the same network as your PC.

new The fuel overlay now answers in laps as well as minutes It shows how many laps of fuel are in the tank, how many laps until you have to pit and which lap that is, with the equivalent in minutes next to each one. In a timed race it also estimates the lap the flag will fall on. Previously a timed race showed only the minutes until your stop, so the lap you were counting down to never appeared.

new Live lap delta as a dashboard field The running comparison against your best and last lap can now go in any dashboard cell, header, footer or widget, not just the Delta Trace overlay. Available in Le Mans Ultimate, AMS2, ACC, Assetto Corsa, AC EVO and AC Rally.

new Best lap, session and car details outside iRacing The race recap card and the Twitch "!best" command only ever knew your best lap in iRacing. They now work in Le Mans Ultimate, AMS2, ACC, Assetto Corsa and AC Rally too. Session type, best lap, pit status, track length and brake bias now show for Assetto Corsa and AC Rally as well, wherever you place them.

new Highlight the drivers you are actually racing The Relative and Standings driver name can now change colour when that car is within striking distance, so a glance at the list tells you who is in play. Turn it on under the Driver field's advanced options and pick the range you consider a battle: 1, 1.5 or 2 seconds. It is off unless you switch it on.

new Standings can shrink to the size of the field A new Box size option lets the standings overlay end at the last car in the session instead of always reserving room for the full row count, so the row count becomes a limit rather than a fixed footprint. Choose Fixed if you would rather it always take up the same space.

Fixed

fix Engine rumble across the whole rev range Below idle the engine effect dropped to a pitch too low for most bass shakers to actually move, so pulling out of the pits felt like nothing, and at a steady idle the note could swell louder and softer instead of holding. Rumble now stays in range and stays put on every sim, and in F1 a single odd reading from the game can no longer convince Track Impulse the car revs higher than it does. If you had turned your engine pitch slider down for a deeper rumble, you gain the most back.

fix Gauges, fuel and G-force now read correctly on every sim A pass over every sim's telemetry brought the dash gauges into line: real per-car redlines and a working shift light in ACC, Assetto Corsa and AC Rally, a steering wheel that moves properly in AMS2, Assetto Corsa, AC EVO, AC Rally, ETS2 and BeamNG, and correct gear numbering in AC Rally. Fuel readouts and fuel-per-lap learning now work in AMS2, ACC, Assetto Corsa, AC Rally, AC EVO and ETS2, the G meter reads in AC EVO, AMS2 and BeamNG with left and right the right way round, AC Rally reports wetness and temperatures properly, and ACC no longer shows days remaining in a twenty minute session. Anything your sim genuinely does not provide now reads N/A rather than a zero.

fix Relative, Standings and Spotter accuracy The Relative now places every car on the right side of you, with gaps that hold steady across the start and finish line, and the Battle Bar names the two drivers the right way round. AMS2 sorts by real track position rather than marking the whole field as "+0.00", and its spotter works out which side each car is really on instead of calling everything to the right. Standings takes its size from the session in front of you, gives every class the rows you asked for, and keeps its bottom bar attached to the last row.

fix Overlays stand on their own, and settings apply straight away The overlays now recognise BeamNG, Assetto Corsa, ACC and AC Rally by themselves, so they no longer need the main app running alongside them. The "Restore last settings?" prompt asks once per sim instead of every time you move between the menu and the track. Widget decimals, scale, battle thresholds, closing arrows, fuel averaging, the car column's logo style and the Relative's gap colours all take effect on screen as you change them, sector times fill in outside iRacing, voice callouts work on every spotter style, mirror windows and the Stream Canvas reopen where you left them, and learning a new track no longer hitches the display.

fix Performance Review reads the lap the way you drove it The Line tab drew your lap as a mirror image, so a clockwise circuit came out anticlockwise and the left or right readout was inverted. Your line is now drawn onto the same track map every other tab uses, with your lap and the reference as two separate lines. Pausing mid lap no longer inflates your delta or poisons the reference lap, laps using Active Reset are recognised for what they are, and your cornering peaks and lap statistics clear when you change car, track or session.

fix Fuel strategy and race information A splash and dash, or a stop for tyres only, made Track Impulse read that lap as an unusually economical one and remember the wrong figure for that car and track. Stops are now recognised properly. The race recap card waits for the chequered flag rather than the first waved yellow, red flags show as red, and Le Mans Ultimate's stint and energy panels recover after a dropped connection instead of sitting at zero for the rest of the race.

fix Audio devices, testing and setup An ASIO driver that cannot report a usable sample rate or buffer size is now refused with an explanation rather than opened anyway, which is what produced a loud continuous tone through the shakers. Unplugging and replugging your interface between sessions reconnects without a sim running, holding a test button and alt tabbing away stops the test, cancelling a setup wizard restores exactly what you had, and rigs with two ASIO interfaces get working test buttons throughout. On Simagic pedals a shift now adds a thump instead of interrupting the rumble.

fix Sims are recognised, and remembered, correctly Switching sims without restarting now brings the right effect cards and the right track map with it, and changing car or track mid session is picked up while you play, so calibration and rev learning are filed against the car you are actually in. Assetto Corsa learns your car whichever order you start things in, AC EVO is let go of properly when you close it and no longer triggers the pit helper on the straight, AMS2 falls silent if the game crashes and feels the same at 60fps as at 144, ETS2 keeps each truck's learned feel, BeamNG treats each vehicle separately and tells you when something else is holding its port, and AC Rally leaves the shakers alone during replays.

fix Clicks land where you click, on any monitor After scrolling the effect list, a click or a slider drag could act on a different effect than the one under your cursor, clicking the panel header could grab the master volume dial, and the small round knobs in the advanced settings could stay grabbed if you released the mouse outside the window. All three are fixed: worth a look at your rev limiter and engine start levels if either is sitting at an odd extreme. The window also stays sharp and correctly aligned when you drag it to a second monitor running different scaling, and the standalone Tachometer widget now matches the dashboard dial exactly.

fix Profiles do exactly what they say Overlay profiles now carry layout and overlay settings only. Save All covers all ten sims, and importing, deleting or renaming a profile does exactly what it says.

fix The overlay app is now fully translated Labels, tooltips and settings scattered through the overlays had never been translated and stayed in English whichever language you picked. They are all translated now, in French, Italian, German, Spanish, Portuguese and Japanese.

fix Stability across Track Impulse and the overlays Both apps are steadier this release. The main window recovers on its own after sleep, a graphics driver reset or a card switch, the overlays keep drawing through a Track Impulse update, quitting no longer leaves the app holding your audio device, and Simagic pedals no longer leave a CPU core running hot. Your tuning is protected too: a power cut part way through a save, or a profile damaged by a forced shutdown or cloud sync conflict, can no longer cost you your settings.

Improvements

impr Road texture follows the road properly Road vibration is now sharp and immediate, tracking the surface underneath you in real time and reaching full strength over short changes like a patch of rough tarmac. It is the biggest single step up in road feel the app has had. You may want to revisit your road volume, as it will feel noticeably stronger than before.

impr Seat only and two shaker rigs no longer overdriven When several zones share one shaker, which is what the seat only and two shaker layouts do, their outputs are now managed together rather than simply summed. Gear changes in particular used to arrive harder than the sliders were set for; what you set is now what you feel. Rigs with a shaker per corner are unaffected.

impr Engine rumble no longer distorts at high revs With engine volume and its texture setting both turned up, rumble now holds its character all the way to the limiter on every sim, instead of flattening off at the top end where it should feel most alive.

impr Kerbs in Assetto Corsa EVO respond across the whole slider Kerb strength is now proportional to the hit, so clipping one with a single wheel feels like a single wheel, and the kerb volume slider does something meaningful across its full travel rather than topping out early.

impr More surface feel in AC Rally The suspension effect now picks up the smaller surface detail between the big hits, so a gravel stage keeps talking to you the whole way down it. The sensitivity slider also has more range in both directions, so you can settle on exactly the amount of chatter you want.

impr Smoother transitions on and off track Effects cut off abruptly when you left the track and could carry a trace of the last road surface back with you when you rejoined, and busy moments where several effects competed had a gritty edge to them. Those transitions are now smooth.

impr A sharper, more accurate driving line Your line is recorded at four times the detail it used to be, so it follows a corner smoothly instead of stepping around it, and where you are around the lap stays accurate all the way to the line instead of drifting as the lap goes on. The Line tab works from your first lap now instead of waiting for five.

impr Cut and messy laps no longer count as your best Performance Review treated every lap the same, so a lap you were penalised for running wide, or one where you spun or made contact, could sit there as your personal best and drag your averages with it. Those laps are now marked in the list and left out of your best, average and consistency figures, out of the lap everything else is compared against, and out of anything offered to the community board. You can still open one and study it.

impr Overlay profiles are no longer tied to one sim Profiles were filed away per sim, so whenever the app had the wrong sim in mind the list looked empty and your saved setups appeared to be gone. Every profile now sits in one list that is always visible, each with a small coloured tag showing which sim it was set up for, and your current sim's profiles are grouped at the top. Setting up a new sim need not start from a blank slate either: load a profile you already like, adjust it, and save it under a new name.

impr Fuel estimate now uses three laps, not one The fuel panel now waits for three clean laps before settling on your fuel per lap, rather than committing to the first one, so the number you plan a stint around has something behind it.

impr Car brand logos are bigger, and always draw clean The manufacturer logos in the CAR column are noticeably bigger and fill much more of each row, so you can tell cars apart at a glance, and they now draw cleanly at every size on round marques like BMW.

impr The glow behind the car maker logo is gone In the Relative and Standings, the manufacturer logo used to sit on an orange glow whenever that car was close to you. It fired constantly in a tight pack and added little the Battle Bar was not already showing, so it has been removed. If you want a close-racing cue in the list, use the new driver name highlight above.

impr The standings Height slider has been retired Standings height comes from its rows and its Text size, so a separate height control could only add empty space beneath the last driver. Use Text size to make the whole overlay bigger or smaller.

impr "Reset to defaults" is now a real button App Settings has a proper "Reset to defaults" button that puts everything back to factory settings, asking you to confirm first. The old "Default" entry in the profile list is now called "Unsaved", which is what it always meant.

impr Toolbar buttons regrouped Options and Overlays now sit on the right hand side of the toolbar, next to the profile and sim selectors, and the setup buttons close up together on the left. The things you open once while setting up are grouped apart from the things you reach for during a session. The window also stops at the narrowest width that still fits everything, instead of letting the toolbar buttons slide under the selectors.

Known issues

known A short burst through the shakers as an AC EVO session loads About half a second of full suspension impact plays while AC EVO's loading screen is still up, as the game drops your car into its pit box. It stops on its own before you take control, and it only happens in AC EVO. A fix is coming in a later update.

Fixed

fix Estimated iRating change now matches iRacing The projected iRating shown in Standings, Relative, the widgets and the race recap now matches what iRacing actually awards, verified against real posted results, including in small fields and small multiclass classes.

Improvements

impr Car brand logos in the Apex Relative and Standings The CAR column now shows each car's manufacturer logo instead of the written brand name, freeing up room for driver names. During a race the logo gains a subtle glow when that car is within a second of the car it is fighting. Prefer something more compact? The column's advanced settings can switch it to coloured three-letter codes (MCL in papaya, FER in red, BMW in blue), which is also what appears automatically for the few brands without a logo.

New

new Shift light options for the Dash's Shift segment When the dash's Apex layout includes a Shift segment, its settings now offer the same options as the standalone Shift Light overlay: gear digit, shift-point trim, and below-zone behaviour.

Fixed

fix Dash layout editor ignored field choices Picking a data field for a telemetry cell in the dash's layout editor did nothing: the list closed and the cell kept its old field. Choices now apply immediately.

fix Dash G-force bubble moved the wrong way On the Apex dash the G-force bubble dropped when braking and rose when accelerating, the opposite of what you feel in the car. It now moves the right way, with the labels to match.

fix Overlay profiles now restore overlay positions Loading an overlay profile never moved the overlays back to their saved spots. Loading a profile, or restoring your last layout when a sim reconnects, now places every overlay where it was saved, and overlays saved on a screen you no longer have are pulled back onto a visible one.

fix Grey strip above the main window title bar A thin grey bar from the standard Windows frame showed across the very top of the main window. The window now draws edge to edge, with resizing and snapping unaffected.

Improvements

impr Apex dash tacho redesigned to read like a real instrument The rev counter gets a classic tapered needle in signal orange, a smoothly shaded metal ring, bolder scale numbers, a larger speed readout and a glass-like recessed face with soft shadows. Small tidy-ups throughout: the steering wheel spokes no longer poke into the rim, the bottom bar's line fades out behind the dial, and bottom bar text can no longer overlap it.

impr Overlays can be made much smaller Every overlay's size sliders now go down to a quarter of the standard size, so overlays no longer snap back up after you drag them small. Relative and Standings also now shrink fully with the Text size setting in the Apex and Graphite designs, the same way Classic always did: their old minimum size was too large on 1080p screens.

Fixed

fix ASIO sound cards failing to load Some ASIO devices (Creative Sound Blaster among them) could no longer be set up: the wizard showed only 4 channels, the test tone stayed silent, and the app started with no device. Track Impulse now identifies your selected driver in a way that cannot mismatch, so affected devices set up and load normally again. Restarting audio devices is also safe no matter how many ASIO interfaces you run.

fix Device wizard now warns when an ASIO driver fails to load If your selected ASIO driver cannot be started, the wizard now says so on the channel step and suggests using the WDM-KS or WASAPI option for the same hardware, instead of failing silently at the end.

fix Garbled accents in dialog title bars In some languages the title bar of a dialog, such as the device setup wizard, showed accented characters as garbled symbols while the text inside the dialog was correct. Every dialog title now displays its accented and non-Latin characters properly.

New

new All-new Apex overlay design Every overlay has a new signature look: hard-edged motorsport styling, a machined analog tachometer on the Dash, a true radar face on the Spotter, and matching redesigns across Relative, Standings, Fuel and the rest. Pick from four colour themes (Apex Red, Sky Blue, Pit Lane Gold, Daylight). New installs start on Apex; existing setups keep the styles you already use until you switch.

new All-new overlay control panel The overlay window is rebuilt to match the Apex look: a searchable sidebar with one-click toggles and a big live preview showing each overlay's position, scale and opacity. Settings now slide in over the sidebar so the preview stays in view, and any section you have changed shows a Modified marker with one-click Revert.

new Customisable Apex Dash layout The Dash's two side panels are now a grid of swappable slots you arrange in a visual editor: steering wheel, input trace, pedal bars, G-force, shift light, battle bar and more. You can also choose what fills the bottom info strip, including a new Stint counter.

new New Apex tachometer and G-force widgets Widgets now include an Apex analog tachometer (per-car redline, gear, RPM and speed) and an Apex G-force meter with a motion trail, peak-hold marker and auto-ranging scale.

new Redesigned Apex Fuel overlay with a pit countdown The Fuel overlay now answers which lap to pit on: a PIT block with a lap countdown, target lap and fuel to add, escalating to a pulsing red BOX BOX on the final lap. Four layouts (Blocks, Tri-Hero, Compact, Strip) and a smarter fuel bar with a finish-fuel notch.

Fixed

fix Classic dash bottom strip defaulted to the wrong field On a fresh install the fifth slot of the Classic and Graphite dash bottom strips showed Incidents / Limit instead of the intended fuel Range. It now defaults to Range again. If you had already picked your own fields, nothing changes.

fix Shakers no longer keep playing after pausing or exiting a session If a sim froze its telemetry the instant you paused or quit, the shakers could keep playing the last effect (most noticeable in Assetto Corsa). They now go quiet within about a second and resume instantly the moment the sim sends data again.

fix Overlay app could open as a blank, frozen window Launching the overlays while another program was busy in the foreground could produce an empty black window that never responded. It now opens normally whatever else is starting up.

fix Streamer settings could lose your saved Twitch and Pulsoid sign-ins A damaged streamer settings file could quietly blank your saved Twitch and Pulsoid tokens and overwrite the good copy. A damaged value now only affects that one setting, and everything else, tokens included, is left intact.

Improvements

impr Track Impulse now connects to your sim automatically When a sim starts, Track Impulse switches to it straight away and picks up a sim that is already running when you open it. If you then choose a different sim by hand it stays there. To go back to being asked each time, untick Auto-Connect to Detected Sim in Options.

impr Tidier widget setup, with one Tachometer choice A widget's type and its options now sit at the top of its settings, so you pick what the widget is first. The Dash and Digi tachometers are now a single Tachometer widget with a Classic / Apex / Digi style switch.

impr Simpler overlay appearance settings The separate accent colour picker has been removed from the overlay app's Appearance settings. Overlay colours now come from the overlay theme.

New

new Turn anonymous usage data on or off in the overlays The overlay app now has its own "Send Anonymous Usage Data" switch in Settings, so you can change your mind at any time. Each app (Track Impulse and the overlays) keeps its own independent setting.

Fixed

fix Overlay control panel could freeze while a sim was running With a demanding game running, the overlay control panel could stop updating on screen even though clicks still registered. It now stays responsive and recovers instantly under heavy load.

Improvements

impr CPU use improvements The overlay app now uses noticeably less CPU in every state: arranging layouts, racing with many overlays on screen, sitting on a settings page, or idling with chat connected.

New

new Overlays now available in seven languages The overlay companion app is now translated into the same languages as Track Impulse itself: English, French, Italian, German, Spanish, Portuguese and Japanese. A language picker appears the first time you open the overlays (preselecting your Windows language), and you can change it any time from the overlay app's settings.

new Coach view in the Performance Review (iRacing, experimental) A new Coach tab ranks the corners where you are losing the most time against your reference lap and says why in plain English: braking earlier than your reference, slower through the apex, later back to full throttle, or coasting. Click a corner to zoom the map and telemetry graphs to just that section, with markers showing both laps' braking, minimum-speed and throttle points.

new Quick Save on the overlay profile selector The profile picker now has a Save button built into it. Click the disk icon to update your selected profile in place, without retyping its name through Save As; on the Default profile the icon opens Save As so you can name a new one. A small caret beside it holds an Auto-save switch that, when on, re-saves your active profile automatically whenever you disconnect from the sim or close the overlays, so a session's tweaks are never lost.

Fixed

fix Performance Review: removed the per-lap delete button (iRacing, experimental) The small delete ("x") button next to each session in the Performance Review's session list sat right on top of the lap time, making it easy to hit by accident and permanently delete a session's laps with no way to undo. The delete button has been removed; sessions can no longer be deleted individually from this list.

fix Performance Review: stray line drawn across the map near start/finish (iRacing, experimental) On some tracks the coloured map views drew a spurious straight line cutting across the map by the start/finish line. The map segment that wrapped across the start/finish point is now skipped, so the outline stays clean.

fix Overlay hotkeys can now use ALT combinations Setting an overlay hotkey that included the ALT key (for example ALT+R, or F10) did nothing: the key press was never picked up by the hotkey box. ALT combinations now capture and register correctly.

fix Performance Review could crash or freeze after extended use (iRacing, experimental) Using the review window's coloured map views for long enough could crash the overlay app, or leave it frozen and needing End Task. This has been fixed, and the map views stay stable during long sessions.

fix Overlay app no longer locks up when the graphics driver stalls When the graphics driver briefly stopped accepting frames (heavy GPU load, driver hiccups, or tools like RivaTuner hooking the overlays), the overlay windows' drawing could block the whole app for seconds at a time: clicks and window dragging went dead and it showed "Not Responding". The app now checks that the screen is ready for a new frame before drawing one and simply skips ahead when it is not, so the worst a stalled driver can cause is a moment of frozen overlay content while the app itself stays fully responsive.

fix Overlay settings: the row of overlay buttons didn't scroll When more buttons existed than fit across the settings page (e.g. many widget slots), the extra ones were pushed off-screen but still reacted to the mouse in the wrong place. The row now scrolls with the mouse wheel and clips properly.

fix Header/Footer tabs showed on overlays that don't have header/footer strips Opening settings for an overlay with no header/footer strips (Shift Light, Spotter, Dash, and others) still showed Header and Footer tabs that only said "This overlay has no header/footer strips." Those tabs are now hidden for overlays that don't support them.

fix Thin gray line across the top of the overlay control panel window A stray one-pixel gray edge from the window's resize border was visible across the very top of the panel, above the custom nav bar. Removed.

fix Shortcuts: the X button to clear a hotkey could stop working After binding a fresh key to a shortcut row, its X (clear) button sometimes did nothing. Fixed.

fix Fuel overlay: hiding a stat field group left an empty gap Turning off the Per Lap or Remain field group left a blank column in the stat grid instead of the other group's fields filling the freed space. The grid now packs the visible fields together.

Improvements

impr Globe button to recover the overlay language if you pick the wrong one The overlay Settings header now has a small globe icon that opens the language chooser directly. Because it is an icon rather than the word "Language" (which is itself translated), you can always find your way back even if you accidentally selected a language you cannot read.

impr Every overlay now describes itself in its settings Opening an overlay's settings shows a short description of what it does at the top of the panel, just under the search box. Previously only a couple of overlays had one and it sat at the very bottom where long text was cut off.

impr Redesigned overlay Settings page The overlay app's Settings page now has a section list down the left side (Profiles, Stream, Appearance, Units, Window, Shortcuts) showing one section at a time, instead of one long scrolling page. The profile list is more compact, with rename, duplicate and delete always visible as small icons and an ACTIVE tag on the loaded profile. The search box still finds settings across every section.

impr Performance Review now records without the Performance overlay open (iRacing, experimental) Lap telemetry for the Performance Review is now captured in the background whenever you are on track, so you no longer need the Performance overlay on screen to build up review data. A new "Log driving data" switch (on by default) in Settings, on the Performance overlay, and in the Review window's title bar lets you turn recording off; when it is off, nothing is saved to disk.

impr Performance Review: zoom the telemetry graphs with the mouse wheel (iRacing, experimental) You can now scroll the mouse wheel over the telemetry graphs to zoom in around the cursor for a closer look at any part of the lap, in addition to clicking a corner. The Reset button restores the full-lap view.

impr Performance Review: searchable car and track picker (iRacing, experimental) The car/track selector at the top of the Performance Review is now an obvious dropdown button with a searchable menu. Start typing to filter by car or track name, and the list is sorted by what you drove most recently, each entry showing its session count, personal best and last-driven date. Arrow keys and Enter navigate the list; the old side arrows have been removed.

impr Overlay control panel: added an "Always on top" setting A new toggle in App Settings (and in the tray icon's right-click menu) lets you let other windows come in front of the control panel. The in-game overlay HUDs are unaffected and always stay on top of the sim.

impr Standings: My class and other classes now have separate row-count limits The "Max rows" setting used to apply the same budget to every class shown. It's now two settings, one for your own class and one for every other class, so you can trim a crowded multiclass field without also cutting your own class's rows.

impr Header/Footer: added a combined time field and an incidents/limit field A new "Time Left / Total" field shows the session clock alongside its full length, and a new "Incidents / Limit" field (iRacing) shows your incident count against the session's DQ limit (e.g. "3x / 17x").

impr Spotter radar bars: bar width is now adjustable A new "Bar width" slider sizes the two edge bars directly, separate from the existing bar-spacing control.

impr Fuel overlay: the upcoming pit lap now flashes as it gets close The "PIT L{n}" indicator flashes amber two laps out and red one lap out (or overdue), so it's easier to catch mid-race instead of reading it off as plain text.

impr Standings/Relative: added a Pit Time field (iRacing) A new optional column shows each car's most recently completed pit stop duration, and "OUT" for the lap right after they leave the pits. Off by default; add it from the Fields list.

New

new Lap-by-lap telemetry in the Performance Review (iRacing, experimental) Every completed lap now records a detailed telemetry trace (speed, throttle, brake, steering, g-forces, gear, RPM and per-corner time) alongside the session. Click any lap in the review window to see that exact lap on the track map and graphs, and compare it against your best. Older sessions still open as before.

new Corner analysis in the review window (iRacing, experimental) The Corners view now uses the track's real numbered turns and shows where the time goes: minimum speed and time lost or gained per corner against your reference lap. A Spread mode flags the corners where your speed varies most from lap to lap, braking-point markers show how many metres earlier or later you braked than your reference, and turn numbers now run along the telemetry graphs.

new Zoom into the track map and single corners (iRacing, experimental) Scroll over the review map to zoom (drag to pan, Reset to snap back), or click a turn number on the map to frame that corner and narrow the telemetry graphs to just that section of track.

new Export and share laps from the review window (iRacing, experimental) A new Export CSV button saves the shown lap's full telemetry as a spreadsheet-ready file, and Copy Img puts a picture of the whole review window on the clipboard for pasting straight into Discord. Exports contain only car, track and telemetry numbers, nothing personal.

new Choose how much review data to keep (iRacing, experimental) A new Perf history setting caps how many saved sessions are kept per car and track (100, 500, 1000 or unlimited), shows how much disk space the data uses, and can trim old sessions in one click from the review window.

new Sample data in the Performance Review (iRacing, experimental) New to the review window? It now opens with an example session so you can see what it looks like before you've saved one of your own. A Sample button in the title bar lets you switch to it any time, handy if your only saved session so far is a stray partial lap.

new Outline layout mode for positioning overlays When arranging your overlays, a new Layout control switches between Full and Outline. Outline collapses every overlay to a half-opaque labelled box so you can see all their frames at once and drag, resize and line them up without the live gauges getting in the way. Switch back to Full to see them render normally.

Fixed

fix Overlay control panel header stays tidy when the window is narrow Making the control panel window smaller used to stack the top-bar tabs, profile selector and buttons on top of each other, and inside an overlay's settings the Visible switch could slip under the overlay name. The top bar now shrinks items to icons as it narrows, and the Visible switch sits beside the overlay name, so the header stays readable at any size.

fix Performance sessions save after a single lap The Performance overlay used to need three laps before it saved a session; one completed lap is now enough.

Improvements

impr Review window units, dates and weather The review window now follows your mph/kph and temperature unit settings, shows session dates in your local time along with the session type, records air and track temperature and rain for each session, and the Trend view spaces sessions by date with a consistency marker showing how close your laps were.

New

new Twitch chat bot with live telemetry commands Connect the overlay companion to your Twitch chat and viewers can pull your live race data with commands like !lap, !gap, !pos, !fuel, !weather, !delta, !inc and more, answered straight from iRacing or Le Mans Ultimate. Pick which commands are enabled from a card deck in Settings, and an optional announcer posts the available commands to chat on a timer so viewers know what to ask.

new Open a mirror window for a single overlay Each overlay's STREAM settings now has an "Open mirror stream" button under "Show on stream" that opens or closes just that overlay's OBS-capturable window, instead of only the open-all button on the main Settings page. Whether it is open is saved and restored the next time you launch the overlays.

Fixed

fix Overlays can now shrink much smaller Most overlays' minimum size was silently capped at their default size, so their Width, Height and Size sliders could grow them but not shrink them below that, no matter how low the slider went. Every overlay now shrinks all the way down to its slider minimum, whether you use the sliders or drag its edges. (Relative, Standings and Battle Bar were unaffected.)

fix Exported and shared profiles were missing settings Exporting a profile to a file or sharing it online left out newer tuning: per-effect waveform, harmonics and priority, engine cylinder count, the rev limiter settings, and the gear downshift boost. Those settings are now included, so an exported or shared profile is a complete copy of your tune.

Improvements

impr Manage overlay layout profiles from Settings The overlays' App Settings now has a Profiles section for your saved layouts (which overlays are on, plus their size, position and settings). You can update the active layout in place, save the current one as a new layout, and rename, duplicate or delete any saved layout. Your layouts also appear right away when you open the overlays with no sim running, so you can switch or edit them any time.

Fixed

fix Test tone was quiet and buzzy on low-latency devices The channel test tone's fade-in restarted with every audio buffer, so on small buffer sizes (common on ASIO) it played at a fraction of its volume with a rough buzz. It now fades in once and plays at full strength on every device.

fix Gear hold-to-test could double-fire with multiple audio devices With more than one audio device active, holding the Gear effect's test button could trigger extra pulses at an uneven rhythm. It now pulses cleanly once per cycle no matter how many devices you have.

Improvements

impr Lower audio engine CPU use The audio engine now does less work on every cycle. The biggest CPU savings are on ASIO setups.

New

new 16 output zones Track Impulse now supports up to 16 shaker zones, up from 8. New zones start switched off, and existing setups carry over unchanged.

new Up to 4 audio devices The Device Wizard can now configure up to four audio devices at once, so large rigs can spread their shakers across multiple amps and interfaces.

new 16 channels per device A single multichannel interface (such as a 16-output ASIO card) can now drive up to 16 shakers on its own, no second device needed.

new Multiple ASIO sound cards at the same time Track Impulse can now run more than one ASIO interface together, up to four devices in total. The Device Wizard no longer blocks a second ASIO device; a note appears only when two devices would share the same driver.

new BeamNG.drive support in the overlays The overlay companion now works with BeamNG.drive. With BeamNG running, the Dashboard overlay shows live pedals, gear, RPM, speed, shift lights and G-force, and the Haptics HUD mirrors your effect levels. The standings, relative and fuel panels stay blank, since BeamNG has no session or competitor data to show.

new Experimental streaming and broadcast overlays A new suite of streaming tools, all experimental for now: mirror windows and a Stream Canvas so OBS can capture your overlays, live Twitch and YouTube chat with pinnable Featured cards, a garage privacy cover, a live heart rate widget (Pulsoid), a broadcast lower third, a shareable post-race recap card, and new session-flag, iRating projection and Safety Rating widgets. We will keep refining these based on your feedback.

new Deeper Le Mans Ultimate support Three LMU additions: a Virtual Energy box (NRG remaining, battery charge, energy per lap and laps left, boost state and motor map), a Stint panel (stint timer, laps, average lap, fuel or energy used, driver swap counter), and a wetness trend arrow on the Session overlay that shows whether the track is getting wetter or drying.

new Slider explanations on every effect card Hover any Frequency or Sensitivity slider in Advanced Mode and the card's description line explains exactly what that value controls in the current sim, with the real numbers: whether it is the center of a band, the exact playback pitch, or the top of the engine's rev range.

Fixed

fix Setup dialogs now reopen where you left them Zone Setup, Channel Routing, HPR Routing and the Device and Setup wizards now remember their last position on screen instead of re-centering every time. If the monitor they were on is no longer connected, they open centered on your main screen so they can never land off-screen.

fix Zone Setup volume labels no longer overlap With 16 zones the row of volume dials packed its labels too tightly and names like "Custom 10" and "Custom 11" ran into each other. The dials are now laid out in two rows so every label has room.

fix Larger Text size no longer overflows the Standings and Relative rows Turning up Text size on the Standings and Relative overlays grew the text but not the rows, so big text spilled over the row above and below. The rows (and the panel) now grow with the text so it always fits, on both the Classic and the default Grid layouts.

fix AC EVO haptics now work in the pit lane Effects were silent from the pit box until the pit exit line, so revving in the box or driving down the pit lane gave no feedback. Effects now run whenever you are in the car, and still switch off in menus, replays and the pause screen.

fix AMS2 effects no longer cut out at the finish line In a race, crossing the line stopped every effect even while you were still driving the cool-down lap. Effects now continue until you actually leave the car, and still switch off in the garage and pause menu.

fix Setup Wizard now routes effects for ETS2 Applying a shaker layout in the Setup Wizard skipped Euro Truck Simulator 2 when writing effect-to-zone routing, leaving ETS2 silent until routed by hand. The wizard now covers all sims.

fix Smoother multi-device audio Multi-device setups now run each device's effects fully independently, removing a subtle timing interaction between outputs.

fix Wheel Slip pitch sweep restored in BeamNG BeamNG is designed to sweep the slip buzz pitch around the Frequency slider as the slide grows, but the audio engine ignored the sweep and played a fixed pitch. The sweep now comes through as intended; other sims are unchanged.

fix Frequency settings near the top of the slider no longer reset Saved frequency values between 76 and 80 Hz snapped back to 75 every time the app restarted. They now stick.

fix Effect Guide no longer shows a blank Frequency section On the Suspension page the Frequency explanation could come up empty. Long guide and translated text now display in full.

fix Effect Guide no longer closes itself when opened from a card Clicking the ? button on a card (Wheel Slip in particular) could open the guide and immediately dismiss it. It now stays open.

Improvements

impr Road Texture now off by default Road Texture is a constant background effect that works best on a shaker of its own, so it now starts switched off for every sim. Turn it on from its card when you have a dedicated shaker for it; existing setups keep whatever you had. The in-app guide explains the dedicated-shaker approach.

impr Clearer device picker in Zone Setup With three or four audio devices, the Device column now shows arrows on either side of "Dev N" so you can step forward or back through your devices, matching the channel picker beside it. Before, it was a single unlabelled button you had to click repeatedly to cycle.

impr Zone Setup and Channel Routing handle big rigs Both windows now grow to fit up to 16 zones and can be resized or maximized to reclaim space on any screen. When the content still does not fit they show a draggable scrollbar (and the mouse wheel scrolls too), with the column headers and effect labels staying in view. Each window remembers the size you set it to for next time.

impr Setup Wizard supports up to 16 shakers The shaker count picker, naming presets, and channel assignment step now cover 16 shakers, with scrolling in the channel list.

impr Lower CPU use in the audio engine The audio engine now does less work per cycle, lowering CPU load while racing.

impr Advanced effect settings are easier to find Each effect card now has a clearly visible ADV button under TEST that opens the effect's advanced settings, replacing the small gear icon that was easy to miss in the card's corner.

impr Rev limiter trigger point now adjustable past the redline The engine effect's advanced RPM dial defaults to 0 (fires right at the learned redline) and now swings both ways: negative values start the limiter buzz earlier (up to 500 RPM before the redline) and positive values hold it off until past the redline (up to 200 RPM over), so you can line it up with where your car actually cuts.

impr Frequency sliders now stay in the range shakers can play The frequency sliders on Suspension, Fast Suspension, ABS, Gear Change and Wheel Slip now start at 20 Hz instead of 10 (ABS, Gear and Wheel Slip already played at 20 Hz minimum internally). The Engine slider now starts at 80 Hz, since it sets the pitch at redline rather than the whole rumble: the engine still sweeps up from 10 Hz at idle. Saved values below the new minimums are raised automatically.

impr Effect Guide now explains every slider in detail Each effect's guide page gains a full Frequency section (and Sensitivity where the card has one) describing exactly what the engine does with the value in each sim, and Getting Started explains what frequency means for bass shakers. Available in all seven languages.

impr Effect Guide now matches the sim you are on The guide's left-hand list shows only the effects your current sim actually has. Sims with a single unified Suspension card (such as iRacing and Automobilista 2) no longer show separate Slow and Fast Suspension pages, and iRacing gains its Kerb Effect page. The ? button on a card still jumps straight to the right page for that sim.

New

new Zone setup guide Zone Setup now has a built-in animated guide for anyone new to bass shakers. Step 1 shows how an effect finds its shaker on a live signal-flow diagram, playing worked examples like "gear shift into the seat" while a top-down rig map shows which shakers fire. Step 2 replays the exact clicks for two common rigs (2 shakers on a stereo card, and 4 corners plus a seat) on the Zone Setup screen itself, with a moving spotlight and captions explaining each move.

new Text size setting for the overlay control panel A new Text size control under Appearance scales the whole control panel (Small, Default, Large, Larger, Huge) so the text is easy to read on any monitor. New installs now open at the Large size.

new Graphite Racing Green overlay designs The Dash, Relative, Standings, Fuel and Battle Bar overlays each gain four new selectable looks in a shared "Graphite Racing Green" style, alongside the unchanged originals. Layouts offer a choice of colour theme (Graphite green or Blue Glass) and, where it applies, a digital or classic analog rev dial and pedal bars or a live pedal trace. The Relative and Standings add full data grids built for multiclass racing (now the default for new installs), plus compact, gap-bar and floating-row views; Fuel adds full-data, laps-in-tank, pit-planner and race-comparison views; the Battle Bar adds a track bar, threat cards, a gap ladder and a broadcast strip. Pick a style in each overlay's settings.

new Battle bar option on the Relative overlay The Interval column's advanced settings gain a Battle bar toggle: a small bar next to the interval that fills as a car gets within 3 seconds of you, coloured by whether the car is ahead or behind. It can be switched on or off per style, on every Relative look including the original, and the overlay widens or narrows to fit.

new New Graphite widgets Four additions to the floating widgets so you can build your own modular dashboard: horizontal pedal bars with steering, a 5-second input trace, the new digital rev dial, and a one-row info strip with a coloured flag chip. The battle gap, delta, fuel and G-force widgets also gain a matching Graphite skin option.

Fixed

fix Demo mode now shows correct data on every overlay Pressing Demo previously left the newer overlays blank or showing leftover numbers from your last real session. Every overlay now animates with believable data: scripted pit stops, a learned per-lap fuel burn, positions that match the gaps shown, sector times, shift lights, a full field lapping the track map, and regular session-best, yellow-flag and lapped-car highlights. Demo laps are kept fully separate from your real fuel and performance history.

Improvements

impr Inputs overlay retired The standalone Inputs overlay has been removed: the Dashboard overlay shows the same pedals, gear and speed with more detail and better looks. If you had Inputs enabled, switch the Dashboard on instead.

impr Better out-of-the-box overlay settings Fresh installs now start from a fully tuned setup: overlay sizes, styles and opacities match a race-ready configuration (solid panels, the low-profile Graphite dashboard with the analog tacho, a wider fuel panel, lap times on the Battle Bar), and two info widgets come pre-configured with useful session and car readouts, ready to switch on. The Delta Trace overlay now starts off rather than on. Existing setups are not affected.

impr Demo Mode turns on automatically while you adjust an overlay's settings When you open an overlay's settings with no sim running, the live preview now fills with animated example data instead of sitting blank, so you can see your changes as you make them. It switches back off when you leave the settings, and if you toggle Demo yourself it stays as you left it.

impr Cleaner overlay control panel window The overlay control panel now has its own built-in title bar with minimize, maximize and close buttons in the top bar, matching the look of the main Track Impulse window. Drag the top bar to move the window and double-click it to maximize.

impr Redesigned field pickers in the overlay settings The dropdown pickers in the overlay settings now match the rest of the redesign. The Dashboard's telemetry grid is set through a live 2x2 map of the four cells: click a cell, then pick its metric from a row of chips, so it's always clear which cell you're changing. The bottom strip pickers expand into a panel showing every metric as a clickable chip, and the remaining pickers (header, footer, widgets, spotter voice and device, and the profile selector) get a matching restyled menu.

impr Dashboard now defaults to the classic cluster Fresh installs start with the original Dashboard cluster look instead of the low-profile Graphite strip. All the Graphite layouts are still there in the Dashboard's style picker. Existing setups are not affected.

New

new Live delta bar on the Performance overlay (iRacing, experimental) A new Delta section leads the Performance overlay with three readouts: a live bar showing time gained or lost against your session best as you drive, your last lap and its gap to best, and a brief flash after each corner comparing your minimum speed to your best lap through that corner.

new Telemetry traces with time delta in Performance Review (iRacing, experimental) The review window now draws speed, throttle and brake traces under the track map, overlaid on your reference lap, plus a time-delta strip showing exactly where on the lap you gain or lose against the reference. Hover the traces or click the map and both stay in sync. Sessions saved before this update lack the timing data, so the delta strip fills in from your next drive onward.

new Sectors view in Performance Review (iRacing, experimental) A new Sectors tab shows every lap's sector times side by side with the best of each sector highlighted, plus your theoretical best lap next to your actual best. Needs sessions saved from this version onward.

Fixed

fix AC Rally suspension effect constantly active The suspension effect in AC Rally fired continuously because it reacted to the car's static ride height instead of actual suspension movement. It has been rebuilt as a single surface-aware suspension effect (the same unified model as iRacing and BeamNG) that stays silent on smooth surfaces, responds to small bumps, and scales up through big hits, jumps and compressions, adjusting automatically between tarmac and gravel stages.

fix AC Rally road vibration removed The Road Vibration effect in AC Rally sat at a constant level on every surface, tarmac included, adding a permanent drone with no detail. The card has been removed; surface texture now comes through the rebuilt suspension effect instead.

fix Main window opening off-screen after a monitor change If Track Impulse was last closed on a second monitor that has since been unplugged or reconfigured, the window could reopen off-screen with no visible way to bring it back. It now checks that the saved window position is still on a connected monitor and repositions itself onto the nearest one if not.

fix Partial laps counting as personal best in Performance data Tows, resets and out-lap fragments could be recorded as absurdly short "laps", becoming a fake PB that skewed lap deltas, consistency numbers and the review heatmap. Laps are now only recorded when they cover the full track. Previously saved bad sessions can be removed with the review window's new delete button.

fix Performance Review text not scaling Text in the review window stayed tiny when the window was enlarged or maximized; it now scales with the window.

fix Performance overlay layout breaking when stretched wide Resizing the overlay wide used to smear labels and values across the full width with tiny text in between. The content now keeps its proportions and centers itself instead.

fix Wrong turn numbers in the Corners view The focus-corners readout labelled corners with the sector number instead of the actual turn number. Corner chips and callouts now use the track's real turn numbers.

fix Track Map overlay showing blank The Track Map overlay now ships with its track outlines, so it draws on installed copies and in Demo mode instead of showing "No track map". It also used to clear itself the moment you left the track or exited the sim instead of keeping the last map visible; it now keeps showing the map until you load a different track.

fix Track Map "Pit lane" toggle doing nothing The Pit lane setting in the Track Map overlay had no effect: the pit lane was never drawn regardless of the toggle. It now renders correctly when enabled (on tracks where pit lane data is available).

fix "Open Windows Sound settings" link not working when no audio device is detected In the device setup wizards, the link to open Windows' sound settings only worked if at least one audio device was already listed. When no devices were found, clicking it did nothing. It now opens correctly in that case too.

Improvements

impr Performance Review usability The session list now scrolls to reach all saved sessions instead of showing only the newest five, the car/track selector opens a proper list instead of blind arrows, each session row has a visible button to set it as the comparison reference, sessions can be deleted, the speed heatmap gained a colour legend, and the window opens larger by default.

impr Slimmer Performance overlay defaults The Sprint, Corners and Telemetry Trace sections are now off by default so the overlay starts compact and glanceable; all sections can still be enabled in settings. Corner analysis and traces live on in the review window, which is the better home for them.

impr Overlays window visual refresh The overlays control panel has been redesigned around a frosted green glass look: a near-black backdrop, glass cards that lift and glow on hover with a Configure shortcut, overlay previews framed like inset screens with Live and Standby badges, larger glowing toggles, clearer buttons and text, and a slimmer top bar showing the live overlay count next to the Edit mode button.

impr Brighter overlay previews Preview thumbnails in the overlays window used to inherit each overlay's in-game transparency setting, which made them look dark and murky against the panel. Previews now always render at full brightness; your in-game transparency is unaffected.

New

new Pit stall countdown bar (Pit Helper overlay) When approaching your pit box on pit road, a new countdown bar shows remaining distance to your stall. The bar fills as you get closer, changing colour from cyan to green to amber. Configurable range (50-300m, shown in metres or feet) and can be toggled on or off in Pit Helper settings. iRacing only for now.

new Performance overlay (iRacing, experimental) A new overlay with seven configurable sections: G-circle with peak envelope and history trail, sprint timers (0-60 mph, 0-100 kph, quarter mile with trap speed, reaction time), corner analysis (min/max/avg speed per corner with lateral G peaks), input efficiency (throttle/brake/coast percentages and brake-to-throttle transition time), lap stats (best/avg/worst with consistency and average speed), and a telemetry trace showing speed, throttle, brake, steering and lateral G stacked by lap distance. Each section can be toggled on or off. iRacing only for now; other sims show a placeholder. This overlay is experimental and will continue to be refined as it matures.

new G-force widget upgraded The existing G-force widget now shows a fading dot trail of recent G samples and a dashed peak envelope outline, matching the Performance overlay's G-circle.

new Performance Review window (iRacing, experimental) A new offline window for reviewing saved sessions per car and track. Once you finish a run of three or more laps, a session record is saved automatically. The Review window lets you browse past sessions, see best and average lap times and consistency, and step through every lap. The right side draws your best lap onto a map of the circuit as a colour heatmap with multiple views: Speed, Braking, Throttle, Corners (per-corner minimum speed vs. your personal best), a Compare view that overlays a reference lap, and a Best Lap Trend chart. Click any point on the track to inspect speed, throttle, brake, steering and G at that spot. Open it from the overlays grid, the Performance overlay's settings page, or the tray icon right-click menu. iRacing only for now. This feature is experimental and will be refined over time.

Improvements

impr Custom overlay card icons The overlay grid cards now show purpose-built icons instead of generic glyphs. Each icon represents its overlay: pedal bars for Inputs, a radar sweep for Spotter, a fuel drop for Fuel, a tachometer for Dashboard, a podium for Standings, and so on.

Fixed

fix Silent crash at startup on some PCs (no window, no message) On machines with a faulty ASIO audio driver installed, Track Impulse could exit the instant you launched it, with no window and no error, because it tried to start every ASIO driver on the system just to list your audio devices. It now starts only the driver you actually selected (or none at all on a fresh install), so a broken driver you never chose can no longer take the app down. If your own selected driver fails to start, Track Impulse now opens on your sound card's native mode and tells you, rather than crashing.

fix ASIO audio interfaces missing from the device list A connected ASIO interface (such as a Behringer UMC) could stop appearing in the setup wizard, so you could not select it. Connected ASIO interfaces are listed again and load only when you pick them. Known wrapper drivers (ASIO4ALL, Realtek ASIO, KoordASIO and similar) are still shown but clearly marked as wrappers and listed last.

fix ASIO drivers for disabled or unplugged devices cluttering the list Interfaces that are switched off or unplugged in Windows Sound (for example a spare ESI or ASUS card) no longer appear in the device list, matching how it worked before. Track Impulse checks each ASIO driver against Windows' own list of connected devices without starting the driver, so a faulty one still cannot crash the app. If something is hidden that you do need, turn on "Show all devices" to bring it back.

New

new Overlays: Track Map (live circuit map with car positions) A top-down map of the track with live car dots colour-coded by class, your car marked with a white ring, turn numbers, and a start/finish line. The right map loads automatically for the track you are on. Toggle turn numbers, pit lane, and car numbers in the settings. iRacing for now, with more sims to follow.

new Overlays: Battle Bar delta style (every sim) The Battle Bar overlay has a new Delta layout: a centre-zero bar that runs green when you are faster and red when you are slower, with the delta number alongside. A Show toggle switches between full-lap and current-sector delta, and a Reference toggle compares against your best or your last. Works on every circuit sim, with both lap and sector deltas covered.

new Overlays: Pit Helper (pit lane speed assistant) Shows your speed against the pit lane limit as a green, amber, or red bar with a clear limit mark. Also shows pit limiter state and your current pit phase (approach, pit lane, in box), and flashes red if you go over. By default it only appears while you are in the pit lane. Supports iRacing, Le Mans Ultimate, and AC EVO.

new Overlays: build your own widgets (up to 12) Add up to 12 floating widgets on demand. Each one can be a text panel (1, 2, 2x2, or 3x3 grid of any data field), a visual gauge (shift light, tachometer ring, G-force dial, dash tachometer), or a bar (lap delta, battle gap, compact fuel tracker). Every widget is independently movable, resizable, and toggleable. Unused slots use no CPU or GPU.

new Overlays: dash tachometer widget The full dash tachometer is now available as a standalone widget, with its glass face, tick marks, dynamic rev fill, needle, and centre readout (gear, speed, RPM, fuel). Comes in both Blu Glass and Nero Glass themes.

new Overlays: car-brand marks in the Relative and Standings CAR column The CAR column can now show a colour-coded brand chip with a short manufacturer code (for example a red FER for Ferrari) instead of plain text. Each list overlay has a per-column Style choice of Text, Logo, or Both, with Text kept as the default so your existing setups look the same. Around 28 manufacturers are recognised across the supported sims.

Fixed

fix Mobile companion: crash when ETS2 was the selected sim Selecting Euro Truck Simulator 2 on the phone could crash the companion. The list now covers every supported sim.

fix Crash when an audio device was hot-plugged Unplugging or reconnecting a USB audio interface while Track Impulse was running could occasionally crash the app. The rescan now shuts the old device down fully before cleaning up.

fix Crash in the latency measurement test when a device was unavailable Running the loopback latency test could crash if the selected device had gone away. The test now reports a clear error instead of crashing.

Improvements

impr Overlays: redesigned settings window Completely redesigned with a larger, premium layout: a collapsible sidebar, an overlay card grid with live mini-previews, a split-view options panel with a live preview, a profile system for saving and loading named setups, and a per-overlay reset to defaults.

impr Crash logging for faster fixes Track Impulse now writes a diagnostic log if it ever crashes, so problems can be tracked down and fixed quickly. If you hit a crash, you can send the log along with your report.

New

new Overlays: Track Map (live circuit map with car positions) A top-down map of the track with live car dots colour-coded by class, your car marked with a white ring, turn numbers, and a start/finish line. The right map loads automatically for the track you are on. Toggle turn numbers, pit lane, and car numbers in the settings. iRacing for now, with more sims to follow.

new Overlays: Battle Bar delta style (every sim) The Battle Bar overlay has a new Delta layout: a centre-zero bar that runs green when you are faster and red when you are slower, with the delta number alongside. A Show toggle switches between full-lap and current-sector delta, and a Reference toggle compares against your best or your last. Works on every circuit sim, with both lap and sector deltas covered.

new Overlays: Pit Helper (pit lane speed assistant) Shows your speed against the pit lane limit as a green, amber, or red bar with a clear limit mark. Also shows pit limiter state and your current pit phase (approach, pit lane, in box), and flashes red if you go over. By default it only appears while you are in the pit lane. Supports iRacing, Le Mans Ultimate, and AC EVO.

New

new BeamNG: surface-aware suspension effect The suspension effect now detects whether each wheel is on paved (asphalt, cobblestone, metal) or unpaved (dirt, gravel, mud, grass, rock) terrain and picks a different amplitude curve for each. Tarmac gets a steep, sensitive curve where small road bumps produce subtle texture, while off-road gets a lively curve where big hits stand out without saturating on continuous rough terrain. Per-corner crossfade over 0.3 seconds prevents jarring snaps when wheels briefly leave the road surface.

new BeamNG: per-vehicle suspension calibration The engine observes each vehicle's suspension characteristics and fine-tunes the effect within +/-40% of the base curves, following the same iRacing calibration pattern. The wider range covers BeamNG's huge vehicle diversity, from tiny sports cars to rock bouncers. Learned values are saved per vehicle so returning to a previously-driven car starts from the calibrated baseline immediately.

new Overlays: ETS2 now shows engine gauges and a shift light The Inputs-Dash overlay now displays water temperature, oil temperature, oil pressure and battery voltage when driving in Euro Truck Simulator 2, using the truck's own readouts. The shift light also works now, with its thresholds derived from each truck's redline (lights at 80%, shift at 90%, blink at 95%). Only ETS2 is affected; other sims are unchanged.

Fixed

fix BeamNG: suspension effect reworked Surface-aware curves tuned from real driving data give tarmac subtle texture and make off-road lively, with big hits standing out instead of blurring into a constant buzz.

Improvements

impr BeamNG: wheel slip effect has texture instead of a clean buzz Wheel slip now sweeps its frequency with slip intensity: a gentle slide plays a deep growl near the bottom of the range, progressing to a harsh grind at full wheelspin. The frequency slider sets the centre of the sweep. The default waveform is sawtooth with one harmonic, giving a gritty scrubbing feel through bass shakers instead of the old monotone sine buzz.

New

new BeamNG.drive support is now working (still early beta) BeamNG haptics are now in a genuinely usable state, with suspension, ABS and other effects reworked to feel right on real surfaces and vehicles. It remains early beta and still needs work, so expect rough edges and follow the setup guide to enable the Track Impulse mod.

new Battle Bar overlay A compact strip showing the gap to the car immediately ahead and behind, coloured by how close the fight is (green when safe, amber in battle, red when attacking or defending), with an optional arrow showing whether each gap is closing or opening. Four styles: Bar, Stack, Track and Minimal, with configurable battle and attack thresholds and a hide-when-no-battle option. iRacing and Le Mans Ultimate only, since other sims do not report rival car positions.

new Dashboard "Battle" mode for the top bar A new top-bar option shows your on-track gaps in a fight: the car ahead fills the right side in green, the car behind the left in red. Each side appears once that car is within two seconds and shrinks toward the centre as the gap closes, with the gap in seconds on each side. Pick it from "Top delta bar" in the Dashboard settings (iRacing and Le Mans Ultimate).

new Choose your overlay pressure unit (bar / PSI / kPa) A new Pressure setting on the overlays' General page picks the unit for all pressure readouts (oil pressure and turbo boost), independent of the imperial/metric toggle, so you can keep metric speed and temperature while showing pressures in PSI. Defaults to bar, so existing setups are unchanged.

Fixed

fix Euro Truck Simulator 2 telemetry plugin now installs automatically Track Impulse ships the SCS telemetry plugin and now reliably places it into the game so ETS2 connects as soon as you start driving instead of waiting to connect.

fix Overlay clicks no longer blocked where there is no overlay A running overlay could swallow mouse clicks across its window and the area around it, so you could not click the game or desktop beneath until you closed the overlay app. Locked overlays are now genuinely click-through, so only the overlay's own controls (in edit mode) take clicks.

fix Every overlay data field is now selectable Field pickers were silently capped, so the last several fields (lap and sector deltas, plus Fuel/Lap and Range) never appeared and could not be chosen. All fields are now selectable everywhere, and dropdowns near the bottom of the settings panel flip open upward instead of being clipped off the edge.

fix G-meter acceleration and braking were flipped (iRacing) The Dashboard G-meter dot now moves up under braking and down under acceleration, matching how the lateral axis already behaved.

fix Zone volume not saved when adjusted by dragging the knob (all sims) Dragging the zone volume dial in the Routing dialog changed the volume but never flagged the config to save, so the change was lost on exit. Adjusting by mouse wheel or double-click reset was already saved correctly.

fix HPR pedal zone gains and effect routing lost on restart (all sims) Pedal zone gains and per-slot effect routing were reset to defaults on startup even though they were saved correctly. They now load as expected.

fix Rare crash when the graphics device resets while the interface is open If Windows reset the graphics device (a driver hiccup, GPU power-state change or remote-desktop switch) just as Track Impulse was redrawing, the app could crash while painting. Painting now pauses for the split second the visuals are rebuilt and resumes automatically.

fix iRacing track wetness in overlays The Session overlay's Wetness readout now shows live track wetness in iRacing instead of "n/a". iRacing reports wetness as a word (Dry, Mostly Dry, Lightly Wet, up to Extremely Wet), so that is what the overlay displays, with the bar filling to match. Le Mans Ultimate and AC Rally keep their percentage readout.

fix First-run dialogs no longer show as a blank window The welcome and keep-my-settings dialog (and the other first-run prompts) could open as an empty white window that never drew its text or buttons. They now render correctly on a fresh launch.

Improvements

impr Dashboard: clearer layout and larger text The instrument cluster (renamed simply "Dashboard", iRacing) has had a layout pass: a bigger steering wheel and shift light, larger panel labels and telemetry values, more room for the steering area, and a tidier right panel. The lap/sector delta now stretches full-width across the top instead of a small corner box, with a "Top delta bar" setting to pick what it compares against (best or last sector or lap). Wide values auto-shrink to fit their cell instead of wrapping or being cut off.

impr Dashboard: TC and ABS are now selectable fields (iRacing) The fixed TC/ABS readout is gone; TC and ABS are now available like any other readout for any cell in the telemetry grid or the bottom strips.

New

new Inputs Dash: full instrument-cluster overlay A wide overlay styled after a modern supercar digital cluster: a large central tachometer (gear, speed, RPM and fuel range in the hub), a steering wheel with a live 5-second throttle, brake and clutch input trace down the left, an engine and telemetry grid with pedal bars and a G-force meter down the right, and two data strips along the bottom. It ships enabled, centred along the bottom of your screen at half size, and scales with a single Size slider. Two glass themes (Blu Glass, Nero Glass) and two tacho faces (dark or Ferrari yellow). iRacing only for now; cells with no data on a given car simply hide.

new Best-sector delta bar The top-left corner shows a live delta bar that swings green when you are up on your best sector and red when you are down, computed by Track Impulse since iRacing does not expose sector deltas directly. Selectable against your best sector or your last lap's sector.

new Configurable telemetry cells Every cell in the right telemetry grid and the bottom strips can be set to any available readout: water and oil temp, oil pressure, battery, brake bias, TC and ABS, lateral and longitudinal G, lap deltas (vs best, last, optimal, session best), fuel per lap, range, and the new sector delta. The lap and sector deltas are also available in any other overlay's header or footer. Engine warnings (overheat, low oil or fuel pressure) tint the relevant cell red.

new New circular "Disc" spotter style The proximity spotter gains a third display mode alongside Bars and Radar: a compact circular radar inspired by Assetto Corsa EVO's native indicator. Your car sits at the centre and nearby cars appear as blips placed around you. When a car pulls genuinely door to door, a red crescent lights up on the rim pointing exactly where the danger is. It shares the Radar range and "Show car numbers" options.

new Standalone shift light overlay A shift light you can place anywhere on screen, separate from the Inputs box. Out of the box it is a ring around the current gear that sits dark until you near the shift point, then lights amber, red and finally flashes blue at the optimal upshift. Pick from four styles (Block, Gauge, Ring or Meter), size it, and show or hide the gear digit. A Shift point trim slider nudges the optimal point by plus or minus 500 rpm to taste.

new Turbo boost gauge in the Inputs overlay (experimental) An optional boost gauge that sits directly to the right of the gear, in three styles: Clean (a contemporary theme-coloured arc), Digital (an LED segment bar) and Retro (an 80s analog dial with a sweeping needle). It reads boost in bar and fills by how close the car is to its maximum boost. Fed by Assetto Corsa EVO today; cars and sims with no turbo leave it idle.

Experimental

exp Euro Truck Simulator 2 and ATS support (not working yet) Early haptic support for ETS2 and ATS, with road vibration, suspension impact, engine rumble, gear change and wheel slip. This is still work in progress and not functional in this build. A fix is coming in the next release.

exp BeamNG.drive support (not working yet) Early haptic support for BeamNG.drive through a small mod, covering road vibration, suspension impact, engine rumble, ABS, gear change and wheel slip. This is still work in progress and not functional in this build. A fix is coming in the next release.

Fixed

fix Interface becoming laggy after enabling the mobile companion Enabling the mobile companion could leave the interface very sluggish. The companion has been temporarily disabled while this is investigated (see Improvements).

fix Assetto Corsa EVO connects again after its 31 March update AC EVO's update changed the way it shares its data. Track Impulse now matches it, so haptics come through and the car is identified again.

fix iRacing clutch input showing 100% at rest and filling backwards The Inputs overlay read iRacing's clutch-engagement value directly, which is the inverse of pedal travel. The clutch bar now reads 0% when the pedal is up and fills as you press, matching the throttle and brake bars.

fix Overlay and calibration settings now survive updates Upgrading now leaves your overlay layouts and per-car calibration untouched.

fix Overlay settings window forgets its position The overlay control panel now reopens where you last left it instead of being placed by Windows each launch. An off-screen position from a disconnected monitor is pulled back on screen.

fix Demo / Test mode not working while a sim is running The Demo / Test button now always animates the overlays, even with a sim connected, so you can preview or arrange overlays mid-session. Turning it back off resumes live sim data immediately.

fix Demo / Test mode lap counts running off system uptime The overlay Demo / Test feed counted laps from absolute system uptime, so the preview could show nonsensical lap numbers. It now anchors to the first demo frame, so demo laps and fuel start from a clean opening lap.

Improvements

impr Mobile companion temporarily disabled The phone companion has been pulled while a performance issue gets fixed. The in-app server no longer starts even if you had it switched on before, so it can no longer affect performance. Your other settings are untouched and the feature will return in a later build.

impr Overlays button in the top toolbar A new Overlays button in the main toolbar launches the Track Impulse Overlays app directly, instead of opening it separately.

impr Cleaner top status panel with per-device readouts The header status panel now shows Device 1, and adds a Device 2 cell whenever a second output device is connected, so multi-device setups can see both outputs at a glance. Latency is still available from the Latency tool.

impr Reset overlays to defaults A new Defaults button at the bottom of the overlay control panel restores every overlay's position, size, style, colours and visibility, plus all general settings, back to factory defaults. It asks for confirmation first.

impr Demo / Test mode is now a button at the bottom Demo / Test mode moved out of General settings to a dedicated button next to "Edit overlays" at the bottom of the overlay control panel, so it is always easy to reach. The button reads "Stop Demo" while running.

impr Lighter overlay redraw load while driving Overlays now repaint only as often as their content actually changes, instead of every frame. Slow-moving panels like Relative and Standings refresh around 10 times a second while the live ones (Inputs, shift light, haptics HUD and spotter) stay smooth. The result is lower CPU and GPU use during a session with no visible difference on screen.

impr Radar spotter default range The radar spotter now defaults to a 15 metre range instead of 25, so cars appear closer to when they actually matter. Existing setups keep whatever range they were set to.

impr No more placeholder icon in overlay previews The preview panel in the overlay settings no longer shows a faint icon in the middle of each preview frame, so an empty or transparent frame stays empty instead of being confusing.

New

new Suspension auto-calibration on every sim The per-car-per-track suspension learning that iRacing uses now runs on ACC, AC, AC EVO, AC Rally and LMU too. The slow suspension effect quietly tunes its deadzone and range to each car and track over a few laps, starting from the existing built-in values and only nudging within safe limits. AC EVO and AC Rally update on a rolling ~90-second basis since they have no lap counter.

new Per-field overlay options Each column in the Relative and Standings overlays now has an "Adv" button with its own settings: licence colour-coding, interval threat colouring, driver-name format, session-best lap highlight, tyre compound, who's-talking dot, and a filled-row class tint.

new Opponent tyre compound (iRacing) The Relative and Standings overlays can show each car's tyre compound as an F1-style tyre graphic (red soft, yellow medium, white hard, green inter, blue wet) or a letter, and hide it automatically when everyone runs the same one.

Fixed

fix HPR pedal volume not refreshing in Zone Setup Changing a pedal's master volume in the HPR Routing window now updates the matching pedal knob on the Zone Setup page right away, instead of showing the old value until the dialog is reopened.

Improvements

impr Interval colours Choose direction (ahead / behind), threat (highlights cars in battle range), or off, with an adjustable battle range and decimal places.

impr Driver name format The name column can be set per overlay to full, F. Last, surname, 3-letter, or first name.

impr Mobile companion Track Impulse now has a companion web app that lets you control the basics from another device, so you can adjust haptics from your phone or another device if needed.

impr Rename corner zones The four corner zones (LF, RF, LR, RR) in Zone Setup can now be renamed, just like the custom zones. Clear the field to restore the default label.

New

new Warning when iRacing pedal vibration clashes with HPR pedals A footer warning flashes when iRacing's Vibrate Pedals setting is active at the same time as HPR pedal output, since both fight for control of the pedals.

Fixed

fix HPR routing test tone holds steady while connected to a sim The HPR routing test button now keeps its tone playing correctly while a sim is connected.

fix Multiple overlay fixes and improvements A range of fixes and refinements across the overlays.

Improvements

impr Stronger HPR pedal effects across a wider range HPR pedal effects feel stronger and cover a wider range of intensities.

impr Smoother, more consistent HPR engine feedback HPR engine feedback feels smooth and consistent instead of weak or stuttery.

impr Firmer HPR gear change thump HPR gear change feedback lands as a firm thump.

New

new Drag edges or corners to resize overlays Drag the right edge to change width, the bottom edge to change height, or the corner to change both. Width, height, and text size can also be set independently in settings so content reflows cleanly without stretching.

new Live projected iRating gain/loss for every driver The Relative and Standings overlays show each driver's projected iRating change based on current running order. iRacing only.

new Per-class name and Strength of Field in Standings The Standings overlay header and footer rows display each class name and its Strength of Field. iRacing only.

new Filter Standings by class or auto-cycle through all classes Switch between your own class, all classes, or auto-cycle mode, which rotates through each class at a configurable interval.

new Adjust row height independently of row count On the Relative and Standings overlays, row height can be set on its own without changing how many rows are shown.

new Standings overlay has its own configurable column layout Customize which columns appear in the Standings overlay the same way as the Relative overlay, with the two layouts saved independently.

new Redesigned settings panel with scrolling and collapsible sections The settings panel is wider, the content area scrolls, controls are grouped into collapsible sections, and navigation now shows icons and an indicator for each visible overlay.

new Toggle switches replace checkboxes in settings Boolean settings throughout the settings panel now use pill-style toggle switches instead of checkboxes.

new Overlay header card at the top of each settings tab Each overlay's tab opens with a header card showing the overlay name, a visibility toggle, and the edit and lock buttons.

new Search box filters settings controls live Type in the filter box to instantly narrow the visible controls by label or section name. Press Escape to clear, and the filter resets when switching tabs.

Fixed

fix Settings window taller so all Relative columns fit without scrolling At 100% display scaling, all 17 columns in the Relative Fields tab are now visible at once without needing to scroll.

fix New columns now appear in Fields list after updating Columns added in a new version now show up in the Fields list even when loading a saved layout from an older version, instead of being silently dropped.

Improvements

impr Cycle interval control shows precise decimal values The auto-cycle interval setting for the Standings overlay now accepts and displays decimal values, so you can dial in intervals like 2.5 seconds.

New

new Track Impulse Overlays companion app A new companion app shows live sim racing data in transparent, draggable panels over your game. It reads haptic effect activity straight from Track Impulse with no extra setup, works with iRacing and Le Mans Ultimate (switching automatically when it detects either sim), and hides itself whenever no supported sim is running. It ships inside the Track Impulse installer as an optional component, covered by your existing activation at no extra cost.

new Six overlays included Inputs: throttle, brake, and clutch bars, gear, shift lights, and steering position. Session: air and track temperature, rain and wetness, incident or penalty count, time or laps remaining, race phase, and flags. Relative: cars immediately ahead and behind by track gap, with number, name, rating, and pit status. Fuel: automatic burn tracking, tank level, laps remaining, fuel to finish, and a recommended pit fill. Proximity Spotter: edge bars that light up when a car is alongside, coloured by how close it is. Haptics HUD: a live activity level for each of your bass shaker effects.

new Fully customisable overlay layout Drag any panel anywhere and lock it with F6, with a banner on each panel confirming edit or locked mode. Set each panel to show in the car, out of the car, or always, add subtle header and footer strips with track and session info, and tune background colour, opacity, and content opacity per panel from a single tabbed Settings window. All panels use wide horizontal layouts suited to the top or bottom edge of an ultrawide or standard display.

new First-run language picker for the overlay app A language picker appears on first launch so the overlay app starts in your preferred language. You can change it later from Settings with a quick restart.

new Alert when the setup wizard would overwrite your pedals A banner now appears on the pedal setup page when a saved pedal configuration is detected, warning that finishing the step will replace your existing settings.

Fixed

fix Setup wizard pedal page now restores your saved routing The pedal configuration page previously always opened showing all three pedals enabled in default order regardless of your saved settings. It now opens reflecting your actual saved routing.

fix Championship White and British Racing Green themes now persist after restart These two accent themes were reverting to Estoril Blue every time the app restarted. They are now retained correctly.

New

new Advanced Mode button glows softly when inactive The Advanced Mode button pulses gently when it is off, inviting you to explore it. It stays lit when active.

new Car and track identity across all supported sims Track Impulse now identifies which car and track you are running across all supported simulators, enabling per-car features.

new ACC, Assetto Corsa, and AC Rally read car and track automatically Your current car and track are detected automatically in these sims and used to power per-car features.

new Assetto Corsa EVO identifies your car and track AC EVO now reports your current car and track for use in per-car features.

new Per-car engine redline memory in ACC, AC, and AC Rally The engine rev calibration now remembers the redline for each individual car, so accuracy improves automatically over time without any manual input.

new AMS2 is now supported Automobilista 2 joins the supported simulator list with suspension, engine, and wheel slip haptic effects.

new Sim and profile selectors redesigned as styled dropdown pills The sim and profile selectors now match the rest of the app's visual design, with a cleaner popup menu replacing the old system menu.

Fixed

fix HPR enables automatically when a pedal profile is added Previously, enabling HPR required a manual configuration step after adding a pedal profile in Zone Setup. Ticking any pedal now turns HPR on automatically, and unticking all turns it off.

fix Pedal Volumes visible and adjustable without hardware connected The Pedal Volumes section now appears and allows slider adjustments from the configuration screen even when no hardware is plugged in, and shows a clear status instead of a blank label.

Improvements

impr Expert Mode renamed to Advanced Mode throughout the app All references to Expert Mode have been updated to Advanced Mode, including the setup wizard, setup guide, and upgrade prompts.

New

new Setup Wizard rebuilt as focused 5-step flow The wizard now walks through shaker count, layout, sound card, and channel assignment with hold-to-test. The Advanced Device Setup remains available as a fallback.

new Scrollable device lists in Setup Wizard Device lists now support mouse-wheel scrolling and a scrollbar, capped at five visible rows. Expanding a grouped device scrolls it into view automatically.

new Advanced engine haptics ported to ACC, AC, and LMU Per-corner frequency feel, throttle-driven rear weight, cylinder firing texture, and rev-limiter response are now available in ACC, Assetto Corsa, AC Evo, AC Rally, and Le Mans Ultimate.

new Manual cylinder count selector for engine effects A 1 to 12 cylinder stepper is now available in the engine advanced settings for sims that do not report cylinder count automatically. iRacing continues to detect this value from session data.

new HPR pedal actuators relabelled P-HPR1, P-HPR2, P-HPR3 Labels now reflect each actuator's physical cable position rather than an assumed pedal function, since users can connect Simagic's cables to any pedal they choose.

new HPR Pedal Routing dialog for per-actuator effect control A new dialog lets you choose which effects play through each HPR actuator and adjust individual gain levels. It is accessible from both the Zone Setup and Channel Routing screens.

new HPR actuators now play strongest routed effect The fixed per-pedal effect priority rules are replaced by a flexible system where each actuator plays whichever of its routed effects is strongest at any moment. Defaults preserve the previous per-pedal feel.

Fixed

fix Startup crash with corrupted or edited config files If a config file referenced an unsupported sim slot, the app could start up against the wrong settings without warning. It now clamps to a valid sim on startup.

fix Stale effect levels shown on meters after reconnect After a sim dropped and reconnected mid-session, the app's meters could show leftover peak readings from before the drop. Meters now reset correctly when a reconnect begins.

fix App crash during device changes or stream recovery The app could crash when restarting audio during device changes, latency measurement, or stream recovery. Audio restarts are now handled safely in all cases.

fix Setup Wizard controls obscured or unresponsive The device list could overlap the footer buttons, and selecting a sound card with too few channels caused the Next button to silently do nothing. Both are now fixed, with a clear message shown when the card lacks enough channels.

fix ACC and AC engine effects tied to wrong RPM ceiling The engine effect intensity in ACC and Assetto Corsa was normalised against a fixed 9000 RPM limit regardless of the car. It now calibrates to each car's observed redline for consistent feel across different cars.

fix Removed leftover engine spatial tuning dialog A hidden engine spatial tuning dialog remained in the app but had no effect on any sim. It has been removed to avoid confusion.

fix Profile Save now prompts for a name on first save Previously, saving while on the default profile would silently overwrite it, which was confusing given that the Defaults button resets to built-in values rather than that file. You are now asked to choose a name instead.

New

new Rev limiter effect for iRacing A new advanced toggle on the Engine card (off by default) that gives your shakers an ignition-cut feel when the rev limiter activates. The engine note keeps coming through between taps rather than cutting out entirely. It triggers automatically from iRacing's rev limiter signal, with an RPM-proximity fallback so low-rev cars still fire.

new Independent rev limiter volume A dedicated Volume dial sets the limiter's intensity separately from the Engine card volume slider, so the limiter stays clearly felt even when you've dialled the engine rumble down for a quieter background feel.

new Rev limiter tuning dials Three more dials in the engine Advanced Settings let you shape the effect: Depth sets how hard each tap chops (full mute through to no chop at all), Tap Rate sets the cadence from 12 to 20 Hz (slower chug to faster trill), and RPM Margin sets how close to redline the proximity trigger fires.

New

new Unified iRacing suspension effect The old separate shock and spring bands are replaced by a single suspension effect that covers everything from the smallest road noise up to big chassis hits on one effect.

new Suspension frequency reacts to event sharpness Sharp bumps land near the top of the band, broad rolling chassis events land near the bottom, and the slider sets the centre. Stiff cars naturally produce a higher pitch than soft cars on the same surface. The window soft-clips to ±15 Hz of the slider.

new Suspension Sensitivity slider (iRacing) A third slider on the iRacing Suspension card, range -20% to +20%. Positive values make small motion feel bigger (more events register), negative values mute small motion so only larger events come through. Separate from calibration: calibration tracks the car's actual range, this slider is a personal preference layer on top.

new Per-lap suspension calibration iRacing learns each car and track's range, dead zone, and noise floor over a few laps. Soft cars on smooth tracks tighten up automatically, stiff cars on rough tracks widen. The default range was widened so soft cars don't saturate before calibration has run.

new Road texture dead zone Added a dead zone so road texture is not so busy on smooth surfaces.

new Road texture frequency band shifted up Road texture moved from 10-80 Hz to 65-120 Hz so road and suspension effects stay perceptually distinct on a single bass shaker no matter how you set your volumes (suspension sits at 28-49 Hz). The Road card slider range and default value were updated to match.

new Effect priority defaults reordered Suspension takes top priority, then kerb-native and wheel slip, then ABS, then gear and engine, then road. Replaces the previous arrangement where slip outranked ABS and ABS outranked engine.

new 360 Hz physics warning for iRacing If for some reason you have disabled irsdkLog360Hz=1 in Documents/iRacing/app.ini, the console now prints a multi-line warning with step-by-step instructions. The unified suspension effect needs 360 Hz physics for full quality.

Fixed

fix Calibration data refreshes automatically across versions Calibration files are versioned so stored data updates automatically when the calibration math is improved between releases.

New

new New hand-tuned iRacing defaults iRacing now ships with its own explicit default values from the tuning session, rather than falling through to generic per-effect defaults. Existing users get a one-time prompt to press Defaults if they want to pick up the new tuning.

New

new Engine effect scales to each car's redline iRacing engine amplitude and frequency scale per car against each car's real max RPM, resolved from session data and learned at runtime. The frequency slider sets the carrier the engine reaches at the rev limit, ramping up from 10 Hz at idle.

new Engine effect max frequency slider widened The Engine card frequency slider now covers 20-200 Hz (was 10-80) and is labelled "Max Frequency" to reflect that it sets the carrier the car reaches at redline.

new Per-cylinder engine jitter (iRacing) The engine effect now varies its pulse amplitude at the engine's actual firing rate, so a V8, an inline-4, and a V12 each carry a distinct cadence on top of the same RPM-tracked carrier. Cylinder count is pulled from the session data and cached per car. A new Cylinder Jitter row in the engine effect's advanced settings controls how strong the effect is.

new Gear change downshift boost and RPM sensitivity Two new controls in the gear effect's advanced settings: Downshift Boost makes downshifts hit harder than upshifts, and RPM Sensitivity scales the gear change intensity with engine speed (quieter at idle, full strength at redline). Standstill shifts, reverse engagements, and pit-exit R→N→1 sequences all still fire.

new Higher default engine frequency for iRacing Default engine carrier raised from 75 Hz to 120 Hz to make better use of the widened 20-200 Hz slider range. Other sims are unaffected.

Fixed

fix Saved engine frequency above 75 Hz being squashed on load The profile loader was silently clamping any persisted engine frequency above 75 Hz back to 75. It now respects the full 20-200 Hz range of the engine card slider.

Fixed

fix Bluescreen with Thesycon WDM-KS drivers Picking the Windows default endpoint on a Thesycon-based WDM-KS driver (common on pro audio interfaces) could trigger a system crash. The wizard now blocks that combination so it can't happen.

fix Multi-output interfaces defaulting to two channels Interfaces with more than one output pair (Behringer UMC404HD and similar with OUT 1-2 and OUT 3-4) were collapsing to 2 channels in WDM-KS mode. Each output now binds to its own pin and opens with the correct channel count, and the wizard tells matching endpoints apart by full device name.

fix Repeated "device verify mismatch" pop-ups in the wizard On systems with multiple endpoints sharing the same short name, the wizard could spam a verification mismatch dialog. The check now uses the persisted device name and stays quiet.

fix Loopback latency test failing on some interfaces The built-in latency measurement was missing detections on Sound Blaster and a few other cards after a recent capture change. Capture is back on the shared-mode path that worked reliably across the supported interfaces.

fix AC Rally mislabelled in the community profile browser AC Rally profiles were appearing under the wrong sim name in the browse dialog. They now show under AC Rally as expected.

Known issues

known Measure Latency doesn't return a result on ASIO devices The built-in latency measurement currently only completes on WDM-KS and WASAPI outputs. ASIO devices run normally for haptic output, but the measurement tool won't report a number for them.

known Minor GUI polish items A handful of small visual and layout glitches in the interface that don't affect haptic output or core functionality. Being cleaned up across upcoming builds.

New

new Simagic HPR pedal haptics Brake, throttle, and clutch vibration via USB with per-pedal volume controls. Supports P500, P700, P1000, and P2000 models.

new Pedal Haptics card New card in the main view with hold-to-test and connection status. Pedal volume sliders appear in the right rail when an HPR device is connected, and per-pedal enable and gain controls are available in zone setup.

new Kerb effect for iRacing Dedicated kerb card with its own volume, frequency, and routing controls, using iRacing's native rumble pitch signal. Separate from the shock suspension effect.

new Telemetry consent dialog On first run you can opt in or out of anonymous usage stats (version, sim, and event only). Change your preference any time from Settings.

new Device wizard now 4 steps Pick your audio hardware adapter first, then choose from its endpoints. The audio settings button now opens the classic Sound control panel.

new Release notes in update dialog When an update is available, the update dialog now shows what changed in the new version.

Fixed

fix Realtek multi-endpoint adapters merged into one device Adapters with multiple endpoints (e.g. separate "Chair Shaker" and "Buttkicker" outputs) now appear as individual devices instead of being combined.

fix Bass shaker endpoints labelled as "Headphones" were filtered out Realtek assigns the headphone form factor to user-configured bass shaker endpoints. These are no longer excluded from the device list.

fix WDM-KS device name matching failures Endpoints with HD/R modifiers in their driver names now pair correctly with their audio adapters.

fix Shock suspension cutting out on kerbs The shock band now runs every frame regardless of kerb activity, so you feel both effects simultaneously.

fix Machine fingerprint could change between reboots Licence activation now uses a stable hardware fingerprint that persists across reboots and system changes.

fix Duplicate trials from multiple email addresses Activating from different emails on the same machine no longer creates separate trials.

New

new WASAPI Exclusive mode A new audio driver mode for devices with buggy WDM-KS drivers. WASAPI Exclusive bypasses the Windows audio mixer and runs at pro-audio thread priority, giving you a reliable low-latency path when ASIO isn't available.

new Smarter device detection The device list now shows clean adapter names instead of raw driver paths, and automatically filters out HDMI outputs, SPDIF, Bluetooth headsets, and headphones. Only active audio render endpoints relevant to bass shakers appear in the wizard.

new API badges and driver recommendations in device wizard Each device in the wizard now shows an ASIO, WDM-KS, or WASAPI badge so you can see which drivers are available at a glance. A recommendation hint below the driver selector helps you pick the best option for your hardware.

Fixed

fix Disconnected and disabled devices no longer appear in device wizard Bluetooth headsets that are paired but not connected, and devices disabled in Windows Sound settings, are now correctly excluded from the device list.

fix iRacing suspension calibration refined Calibration now filters out quiet-period zeros and off-track spikes, keeping thresholds closer to defaults on bumpy tracks. Spring ceiling raised to accommodate rougher surfaces.

fix iRacing car and track detection on CarIdx 0 Session data parsing could match the wrong section of iRacing's session YAML, causing incorrect car or track identification when the player's CarIdx was 0. Now anchored to the correct Drivers section.

New

new Automatic updates Track Impulse now checks for updates on startup and notifies you when a new version is available. Updates are downloaded and verified with Ed25519 signatures automatically. You can also check manually from Settings.

new In-app setup guide A step-by-step guide for device configuration, zone mapping, and channel routing. Opens in your browser from the subnav bar. Covers single and multi-device setups with annotated screenshots.

New

new Assetto Corsa Rally support AC Rally is now the sixth supported sim, joining iRacing, ACC, AC, AC EVO, and LMU. All seven effects are live: road texture, suspension impacts, kerbs, engine rumble, ABS, gear changes, and wheel slip, with rally-specific tuning calibrated from on-track logs across both tarmac and gravel surfaces.

new Simagic HPR pedal haptics support Native USB integration with the Simagic HPR pedal haptic motors (P500, P700, P1000, P2000). Each pedal gets its own effect mapping driven directly from sim telemetry: brake gets ABS, suspension, road, and engine; throttle gets wheel slip, engine, suspension, road; clutch gets gear change, engine, suspension, road. No SimHub required.

new HPR Pedal Haptics card & per-pedal volume sliders A dedicated HPR card on the main panel showing connection status, device model, and a hold-to-test button. Per-pedal volume sliders appear in the right rail when an HPR device is detected, with greyed-out controls when disabled so you can see what's available.

new Pedal section in Zone Setup Zone Setup now includes a dedicated pedal section with per-pedal enable toggles, volume knobs, and a device model label. Pedal haptics can be pre-configured even without the hardware connected so your settings carry over once you plug it in.

new Per-effect waveform selection Each effect (road, suspension, kerb, engine, ABS, gear, slip) now has its own waveform setting. Choose between sine, square, sawtooth, or noise to change the character of each sensation independently.

new Per-effect harmonics Add harmonics to any effect with control over harmonic count and decay rate, making effects feel brighter or more aggressive. Engine defaults to 1 harmonic for a fuller sound, others start clean.

new Priority-based ducking When total output gets high, lower-priority effects automatically pull back to keep the mix clean and prevent shaker overload. Set priority per effect so the sensations that matter most to you always come through clearly.

new Advanced effect settings panel Each effect card has a new Advanced button that opens a per-effect settings panel with controls for waveform, harmonic count, harmonic decay, and priority. Dial in exactly how each effect should sound and behave.

new Spatial engine rumble Engine vibration is no longer identical across all four shakers. It now oscillates left-to-right based on torque reaction and shifts front-to-back with throttle load. At low RPM the rocking is slower and deeper, at high RPM it tightens up. If you're running four shakers, you'll feel the engine physically move around the rig. Works across all sims.

Improved

impr ACC ABS completely redesigned Rebuilt using a self-calibrating tyre radius approach that isolates pure longitudinal slip from ACC's composite wheelSlip signal. Per-wheel phase offsets give each corner its own independent pulse instead of all four firing in sync. Calibrated from real on-track data across GT3 and prototype cars.

impr LMU ABS reworked Completely rebuilt using a three-layer detection system calibrated from real on-track data, with bias correction for RWD drivetrain coasting offsets. Zero false triggers, and the effect now scales with how hard the ABS is actually working rather than a simple on/off pulse.

Fixed

fix Engine Spatial Tuning reset button The Reset button in the Engine Spatial Tuning dialog now correctly restores all six sliders to their defaults. The main Defaults button also resets spatial tuning values.

fix Release notes & update dialogs no longer render blank Release notes and update notification dialogs were rendering blank when notes contained line breaks. Multi-line release notes now display correctly.

fix Double "v" prefix in release note headers Release note headers were showing "vv0.6.103" instead of "v0.6.103". Now displays correctly.

fix Zone Setup dialog clipping the Clutch pedal row The bottom of the Zone Setup dialog was cutting off the Clutch pedal controls. Dialog now sizes correctly to fit all pedal rows.

New

new Keyboard Shortcuts & Tips panel A new sub-dialog accessible from Settings showing all keyboard shortcuts and usage tips in one place. The old website link button has been replaced with this.

new Global hotkey remapping You can now remap the global hotkey (default Alt+Shift+T) to any key combination from the Settings dialog. Useful if the default conflicts with other software.

new New user link on the licence screen A clickable "New user? Visit track-impulse.com/download" link on the sign-in screen so first-time users don't have to go hunting for the download page.

Improved

impr WDM-KS latency readout The latency figure shown in the header for WDM-KS streams now shows estimated total pipeline latency (buffer period plus driver overhead) labelled "Estimated", so it's clear what you're looking at and why the number is higher than an ASIO equivalent.

Fixed

fix Audio engine multi-device reliability Fixed a bug in multi-device setups where output could be sent to the wrong device after another device was removed. Also fixed an issue in the loopback latency test and a sound card probe that could list the same sample rate twice.

fix Device Wizard issues Multiple device selection and testing issues were resolved which were preventing some devices from being shown in the devices list.

fix Licence screen layout overhauled Crash on first launch in standalone mode is fixed, and the licence screen has been cleaned up: the wordmark, heading, and subheading are now properly sized, and the EKG sweep animation no longer overlaps the wordmark or runs off the edge of the panel.

fix Console window close button disabled Clicking the X on the debug console was terminating the whole process. The close button is now removed from the console window so it can't be accidentally closed mid-session.

fix Dialogs now centre correctly when launched at startup Dialogs that open before the main window exists (like the licence screen) could end up off-screen on some setups. They now centre on the primary monitor.

New

new Fully rebuilt UI Every dialog has been rebuilt from scratch: device wizard, zone setup, channel routing, profiles, update notifications, and the licence screen. Crisper text, consistent dark styling, and smoother interactions throughout.

new Accent colour themes Nine colour themes to choose from in Settings: TI Rosso (the original red), Hemi Plum, Ruf Yellow, Estoril Blue, British Racing Green, Championship White, and more. Changes apply live across the whole interface.

new Card density setting Three card sizes in Settings, named after cars because why not. Suzuki Cappuccino fits more on screen, GR86 is the default, BMW M5 gives you extra breathing room. Useful if you run TI on a smaller display or at a distance from your rig.

new Motorsport-style effect enable buttons The numbered toggle on each effect card has been replaced with a round illuminated start/stop button. Accent-filled ring when on, muted ring when off. Same hit area, cleaner look.

Improved

impr Lower CPU when idle or minimised The app now uses a much slower refresh rate when no sim is connected, and skips rendering entirely when minimised. Should be near-zero CPU when sitting in the background between sessions.

Fixed

fix ASIO latency display showing wrong value The latency number in the header was showing roughly 3x the actual buffer latency. A 64-sample/48kHz buffer now correctly shows ~1.3ms instead of ~3.5ms.

fix App going behind other windows when closing dialogs Closing the device wizard, routing dialog, or zone setup was sometimes sending TI behind the sim window. Fixed: focus now returns to TI after every dialog close.

fix Update notification appearing repeatedly The update available popup was re-appearing on every timer tick instead of showing once. It now appears once per session.

New

new Per-effect-per-zone volume control in Channel Routing Set exactly how much of each effect reaches each zone with fine-grained sliders. Right-click to mute/unmute, double-click to reset, scroll wheel for fine adjustment. Old profiles auto-migrate.

new Save/Load in Channel Routing Save and Load buttons added to the Channel Routing dialog footer.

new Channel Routing help text Muted help text below the header explaining drag, right-click, scroll wheel, and double-click interactions.

new Profile stepper arrows Arrow buttons in the toolbar now cycle through all saved profiles for the current sim.

new Global hotkey Alt+Shift+T (configurable in Settings) to show or hide Track Impulse from any app.

new Return to Sim button Quick minimise button in the bottom bar with a hint showing your configured hotkey.

new VR auto-minimise Detects SteamVR and minimises Track Impulse automatically after 10 seconds. Toggle on or off in Settings.

new LMU vehicle name detection Vehicle name is now read from telemetry each frame for future per-car tuning.

Improved

impr Refreshed UI design Textured panel backgrounds, wider landscape effect icons that double as on/off toggles with hover glow and press feedback, activity strip and glow border removed for a cleaner card design, and a fixed 1080x1080 window with no more resize quirks.

impr Lower CPU usage Console updates at 2Hz instead of 30Hz when a sim is connected.

impr Console warning dialog A confirmation dialog now appears before opening the debug console, with a "don't show again" option.

Fixed

fix AC EVO wheel slip retuned Retuned from GT3 and GR86 edge-of-grip driving. Lockups and spins no longer produce extreme spikes.

fix AC EVO ABS rewritten Now tracks real per-wheel ABS cycling from telemetry instead of a synthetic pulse.

fix LMU bias calibration improved Braking transients no longer absorbed as false zero-points. More stable convergence.

fix LMU engine rumble frequency fixed Now sweeps smoothly from idle to redline instead of scaling incorrectly.

fix LMU ABS significantly improved Per-class slip thresholds: GT3/GTE get a tight, precise feel while LMP/Hypercar get a raw, aggressive feel matching their crude or absent ABS systems. Fixed an issue that was crushing output to a fraction of the slider value.

fix Save As dialog text overflow fixed Profile name length capped to 31 characters to prevent text wrapping.

New

new Assetto Corsa EVO support AC EVO is now the fifth supported sim. Full haptic engine reading native shared memory at the render frame rate with all seven effects: road texture, suspension impact, kerb, engine rumble, ABS, gear change, and wheel slip.

new AC EVO electric vehicle detection Engine rumble is automatically suppressed for electric cars. The console shows an [EV] or [ICE] indicator so you can see what was detected.

new AC EVO native ABS detection ABS feedback uses Kunos' own ABS active flag directly rather than estimating slip from wheel speeds. Cleaner activation with no false triggers.

Improved

impr GPU-accelerated rendering The entire interface now renders on the GPU instead of the CPU. Every window, dialog, and panel is hardware-accelerated, giving smoother resizing, sharper scaling, and lower CPU usage.

impr High-DPI display support Per-monitor DPI awareness so the UI scales correctly on high-resolution displays and multi-monitor setups with mixed scaling.

impr Dark scrollbars Scrollbars in the card panel and settings dialog now match the dark theme instead of appearing as bright Windows defaults.

impr Settings dialog is now resizable Drag any edge to resize the settings window. Scroll range and layout adjust automatically. Minimum size 400x500.

impr Cleaner upgrades The installer now silently preserves your licence and profiles while cleanly replacing all other files. No more manual prompts during upgrades.

Fixed

fix Device wizard API selection restored The previous wizard rewrite had dropped the per-device audio driver toggle, forcing ASIO on dual-API devices with no way to select WDM-KS. The API row is back on step 2 when the device supports both.

fix Device wizard remembers your API choice Reopening the wizard now shows the API you previously selected instead of always defaulting to ASIO.

fix Effect meters fixed for multi-device setups If you use two audio interfaces, the effect level meters were only showing output from the last device. They now show the combined peak across all devices.

fix Wizard channel test buttons match actual channels Step 3 of the device wizard now reads back the actual opened channel count after fallback, so per-channel test buttons always match what the device is actually doing.

fix Legacy config fields removed Cleaned up duplicated audio settings that could cause stale values on startup. The device configuration now reads from a single source.

New

new LMU dual-band suspension Suspension feedback for Le Mans Ultimate is now split into two bands: slow suspension captures body roll and heave, while fast suspension detects sharp hits with sustained detection and additive kerb boost. Per-class dynamic scaling adjusts for Hypercar, GT3, and other car types.

new LMU wheel slip Wheel slip is now fully working for Le Mans Ultimate. Feel sustained slides, snap oversteer, and understeer through the shakers. Uses steer-to-yaw calibration and a yaw amplifier for natural-feeling feedback.

Improved

impr LMU defaults updated from on-track tuning All LMU effect defaults have been revised from logged data across multiple cars and circuits. Dual-band suspension enabled by default. Road Texture and Wheel Slip cards now visible in the GUI.

impr LMU added to Advanced mode LMU now supports the dual-band suspension toggle on the suspension card, matching ACC and AC behaviour.

New

new Singer-inspired gauge UI All effect knobs have been replaced with high-resolution bitmap dial faces in three styles (Volume, Frequency, Sensitivity), each with a red needle and machined hub cap. Cards now have a bevelled gradient background inspired by CNC-machined metal panels.

new Bitmap toggle switches The old drawn toggle switches have been replaced with rocker switch bitmaps for a more tactile look.

new Click-to-set on dials Click anywhere on a dial face to jump directly to that value. No need to drag from the current position.

new Value readout inside dial The current value and unit are now displayed inside the dial face at the bottom centre, replacing the external label for a cleaner layout.

Improved

impr Gear Change simplified to 2 knobs The duration knob has been removed from the Gear Change card. Duration is now fixed at 7ms for a consistently snappy response.

impr Frequency minimum raised to 15Hz All frequency dials now start at 15Hz to match the dial face artwork and stay within the useful bass shaker range.

New

new Redesigned licence dialog The activation and onboarding screen has been rebuilt with a motorsport-styled design, clearer beta access messaging, and an improved success state layout.

Fixed

fix Titlebar latency not updating after device change The latency display in the titlebar and status panel was not refreshing after selecting a different device in the wizard.

fix Device wizard cleanup on device removal Removing a device in the wizard was not clearing its ASIO CLSID or remapping zones, which could leave stale config behind.

fix Keyboard shortcuts blocked by card panel Keyboard shortcuts were being swallowed when the effect card panel had focus instead of passing through to the main window.

fix Tray icon click restoring correctly Clicking the tray icon was sometimes triggering the update banner instead of restoring the window. Fixed.

fix Dialog flicker on wizard, routing, and zone setup The device wizard, routing, and zone setup dialogs had a subtle flicker when opening. Fixed.

fix Community profile downloads working correctly Downloading a shared community profile was failing. Fixed, along with a related problem in profile uploads.

fix Some global settings ignored on startup A problem in the configuration file was causing some global settings to be ignored when the app started. Fixed.

New

new Redesigned UI The entire interface has been rebuilt with a motorsport-inspired card layout, custom GDI+ knobs, toggle switches, and vector icons. Each effect gets its own card with controls inline.

Improved

impr Effect level meters Right-click the main window to hide the meters panel. Keep it tidy, pull it up when you need it.

New

new Multiple audio interfaces supported simultaneously You can now assign different output zones to different audio interfaces. Run your front shakers through one card and your rears through another. Configure it in the device setup wizard.

Improved

impr Device wizard warns when two ASIO devices are selected If you select two ASIO devices in the setup wizard, a clear warning explains that only one ASIO device can output at a time and suggests switching one to WDM-KS.

New

new Measure Latency button A new button in the GUI lets you measure your actual audio roundtrip latency using a loopback cable. Compares measured vs driver-reported latency so you can see exactly what your hardware delivers.

Improved

impr Accurate latency display The latency shown in the console and GUI now correctly reflects buffer size plus driver pipeline delay. ASIO shows buffer-only latency, WDM-KS includes the additional driver overhead.

impr Updated iRacing default tuning Revised default values for wheel slip sensitivity, ABS frequency, and wheel slip frequency based on extended testing. Existing profiles are not affected.

New

new Settings dialog with setup guide A new settings gear button opens a dialog with a startup guide for new users and a "What's New" summary after version updates. Includes tips on effect priorities and how to get the best feel from your shakers.

new iRacing wheel slip effect Wheel slip is now available for iRacing. Feel oversteer, understeer, and tyre slides through your shakers with a per-corner sensitivity slider to dial in the response to your preference.

new Zone wizard volume sliders The Setup Shakers wizard now includes per-zone volume sliders, synced with the main GUI sliders in real time. Easier to balance your shakers during initial setup.

Improved

impr LMU ABS detection improved More accurate per-wheel lockup detection using a self-calibrating system that adapts to each car automatically.

impr Updated iRacing default tuning Revised default values for several effects based on on-track testing. Existing profiles are not affected.

impr Brighter label text GUI text brightness increased for better readability when sitting a few feet away in the rig.

Fixed

fix iRacing slide detection improved Fixed an issue that was reducing the accuracy of oversteer and slide detection in iRacing.

fix Profiles page loading fixed Resolved an error preventing the cloud profiles page from loading shared profiles.

Improved

impr ABS effect reworked per sim ABS effects have been reworked across all sims and a bug removed which was causing iRacing to use an older model. Each sim now has its own tuned ABS detection for more accurate feedback under braking.

impr Close-to-tray now defaults to off Fresh installs no longer minimise to the system tray by default. The option is still available in the right panel if you want to turn it on.

Fixed

fix Zone volume sliders corrupting visually Adding or removing shaker zones in the Setup Wizard could leave ghost slider graphics on screen. The panel now redraws cleanly after any zone change.

fix Effect Levels section not moving after zone changes The effect level meters and their header were not repositioning when the number of zone sliders changed, causing overlap. They now sit correctly below however many zone sliders you have.

fix Zone summary not updating after wizard changes The zone-to-channel hint label below the volume sliders was not refreshing after applying changes in the Setup Wizard. It now updates immediately.

fix Console text wrapping on all sims The console window was too narrow for its column layout, causing the per-corner output rows to wrap and become unreadable. Widened to fit correctly.

fix LMU console showing Wheel Slip as active The LMU console was displaying a Wheel Slip row with four columns of zeros, making it look like the effect existed but was broken. It now shows as "n/a" since wheel slip is not yet implemented for LMU.

New

new Le Mans Ultimate support LMU is now the fourth supported sim. No third-party plugin required, just enable "Plugins" in LMU Settings > Gameplay. All seven effects supported.

new Up to 8 output zones with flexible routing The old 4-channel model (front-left, front-right, rear-left, rear-right) has been replaced with a zone-based system supporting up to 8 named output zones. A new Setup Shakers wizard lets you map each shaker location to an audio channel. A Channel Routing dialog lets you choose which effects play through which zones. For example, send suspension and kerb effects only to corner shakers, or route engine rumble to a seat shaker. Per-zone volume sliders replace the old per-channel sliders.

new Audio device setup wizard A guided 3-step wizard now launches on first run to help you select the right audio device. It shows only ASIO and WDM-KS capable devices, recommends ASIO when available, and explains the latency difference. Also accessible any time from the Setup Wizard button in the device section.

new Profile save, load, and sharing Save multiple named effect profiles per sim with Save As, Load, and Delete. Export profiles as standalone .tiprofile files to share with others, or import someone else's. Cloud sharing lets you upload your profiles and browse community profiles directly from the app. Ctrl+S saves the current profile instantly.

new Minimise to system tray Closing the window now hides the app to the system tray instead of quitting. Right-click the tray icon to Restore or Exit. The console window hides and restores with the main window. A checkbox in the right panel lets you turn this off if you prefer the old close behaviour.

new Effect level meters Seven real-time bars in the right panel show exactly what each effect is outputting to your shakers. Green through yellow to red, with fast attack and slow decay so transient hits are clearly visible.

new Tooltip hints on effect labels Hover over any effect label to see a short description of what it does and how to adjust it.

new Single instance detection Launching the app a second time now brings the existing window to the front instead of opening a duplicate.

new Unsaved changes indicator An asterisk appears in the title bar when you have unsaved changes to your profile. Disappears when you save.

new Config backup on every save A .bak copy of your config is created automatically before each save. If your config ever gets corrupted, the backup is there.

new Taskbar flash on sim connect If the app is minimised to the tray and your sim connects, the taskbar icon flashes to let you know it's running. The tray tooltip also shows the connection status.

Improved

impr Test buttons now play realistic patterns Hold-to-test buttons have been reworked to play animated patterns instead of a flat buzz. Suspension fires sharp hits, kerb plays rapid-fire rumble strips, engine sweeps through the rev range, ABS pulses like a real system, and wheel slip builds and fades. All patterns respond to your current slider settings in real time.

impr Existing profiles automatically upgraded Your existing effect profiles are automatically migrated to work with the new zone routing system, so all effects default to your four corner zones and everything works the same as before until you customise it.

impr LMU suspension adapts to car class LMU suspension thresholds now start from a class-appropriate baseline (lower for Hypercar/LMP2, higher for GT3/GTE) and then dynamically scale to match the track surface. Smooth tracks stay sensitive, rough tracks raise the threshold so you feel the big hits without constant noise.

impr Window size and scroll position remembered The app now opens at the same size, position, and scroll position you left it at. First launch defaults to a smaller, more sensible window height.

Fixed

fix WDM-KS audio dropouts now recovered automatically If the audio stream stalls or drops out on WDM-KS devices, the app now detects it within 2 seconds and restarts the stream automatically. Up to 3 retries before giving up. Previously a dropout required restarting the app.

fix No audio output on some ASIO interfaces Fixed an issue that caused some ASIO audio interfaces to receive garbled or silent output.

New

new ACC wheel slip sensitivity slider The wheel slip effect now has a sensitivity slider (1-100%) that adjusts how easily tyre slip triggers haptic feedback. Default is 50%. Turn it up to feel mild understeer, turn it down if it fires too often. Tuned from extensive logged data across multiple driving scenarios.

new LMU groundwork: integration started Le Mans Ultimate integration work began. Shipped in v0.5.0.

Fixed

fix AC ABS effect constantly buzzing on every car with ABS The app was misreading AC's ABS setting as an active intervention signal, causing a constant buzz during any braking on ABS-equipped cars. Fixed: ABS haptics now only fire when your wheels are actually locking or the ABS system is intervening.

fix AC ABS not detecting wheel locks on some cars The fixed tyre radius used for ABS detection didn't match all AC cars, so some cars with smaller tyres would never trigger the ABS effect even during full lockups. Replaced with a detection method that works across all car types.

fix Channel volume sliders had no effect The per-channel gain sliders were not being applied to the audio output. Adjusting front-left, front-right, rear-left, or rear-right volume now works as expected.

fix Test buttons not matching slider levels The hold-to-test buttons were playing effects at a fixed intensity instead of using your current slider setting. They now match exactly what your sliders are set to.

fix AC missing yaw rate, steering torque, and clutch data Some newer data fields from Assetto Corsa were not being read. Effects that depend on yaw rate and steering input now work correctly.

fix GUI layout breaking when switching between sims Switching between ACC and iRacing with the Advanced suspension toggle enabled could cause missing rows or visual glitches in the effects panel. The layout now reflows cleanly on sim change.

Improved

impr ACC wheel slip tuned from logged data Wheel slip detection recalibrated from real driving data. The effect no longer fires during normal cornering, only genuine tyre slip events come through.

impr Fast suspension frequency now sweeps dynamically The fast suspension / kerb effect in ACC and AC now modulates its frequency based on hit intensity: lighter impacts play at a higher pitch, heavier hits at a lower pitch. Gives a more natural, varied feel across different kerb types.

impr Suspension toggle restyled The Simple/Advanced suspension mode selector for ACC and AC now uses a red square toggle consistent with the rest of the interface, replacing the previous radio button style.

Fixed

fix iRacing kerb effect not working on mild kerbs Kerbs that don't produce a native rumble signal from iRacing were being ignored because the fallback detection threshold was set far too high. Lowered significantly, so mild kerbs and bumpy kerb strips are now felt clearly. The frequency slider also now responds correctly when the sim is providing kerb frequency data.

New

new Assetto Corsa fully supported Assetto Corsa is now fully supported alongside iRacing and ACC. All effects are working: suspension, kerbs, ABS, wheel slip, engine rumble, and gear change.

new Two suspension modes for AC Assetto Corsa now supports the same Simple / Advanced suspension split as ACC. Advanced mode separates slow suspension (road feel and bumps) from fast suspension (sharp kerb hits and high-speed impacts).

Improved

impr AC suspension tuned from logged data Suspension sensitivity recalibrated from on-track data. Minor road texture no longer triggers the suspension effect, only real bumps come through. Road vibration handles surface detail separately.

New

new ACC suspension effects tuned from extensive on-track logging Suspension sensitivity in ACC has been calibrated from extensive on-track testing across smooth straights, bumpy sectors, painted kerbs, and sausage kerbs, giving the effects accurate thresholds and a wide dynamic range from small bumps through to kerb strikes.

new Assetto Corsa support Experimental Assetto Corsa (the original) is now selectable in the sim dropdown. This is an early preview, most effects are not yet working. Not recommended for everyday use; select it if you want to test and report back.

new Two suspension modes for ACC ACC now offers a choice between Simple and Advanced suspension. Simple covers the full range in one band, road texture through to sausage kerbs. Advanced splits into two separate effects: a slow suspension channel for road feel, and a fast suspension channel that reacts to sharp kerb hits and high-speed impacts.

Fixed

fix Console showing wrong suspension and kerb values in ACC The suspension, kerb, and road vibration readouts in the console were being calculated separately from the actual effect engine, using stale constants. They now display the real output values, so what you see in the console matches what your shakers are receiving.

Improved

impr Simple mode removed: all controls always visible The app no longer has a separate Simple mode. All effect sliders, frequency controls, test buttons, and channel gain are always accessible without needing to switch modes.

New

new Assetto Corsa Competizione support ACC is now fully supported alongside iRacing. Select your sim from the dropdown in the app, it switches without a restart.

new Hold-to-test buttons for every effect Each effect row in the advanced panel now has a TEST button. Hold it to trigger that effect directly, no need to be in a session to tune your shakers.

new Wheel slip feedback (ACC only) When running ACC, a new wheel slip effect fires when your tyres lose grip, separate from ABS and separate from road texture. Hidden automatically when iRacing is selected.

new Automatic update notifications When a new version is available, the app will let you know at startup with a prompt to download it.

Fixed

fix Advanced controls appearing in Simple mode after a restart If you closed the app in Advanced mode, certain controls (Dynamic Sensitivity button, Wheel Slip sliders) were incorrectly showing up when you reopened in Simple mode.

fix Wheel Slip enabled/disabled state not saving on close Whether you had Wheel Slip turned on or off wasn't being remembered between sessions. It now saves correctly with everything else.

fix ABS detection not working in ACC The ABS effect wasn't firing correctly in Assetto Corsa Competizione. It now detects wheel lock reliably under braking.

Improved

impr Wider app window with longer channel volume sliders The right panel was too narrow and the scrollbar was overlapping the volume controls. The window is now wider, the sliders are longer, and everything has room to breathe.

New

new Simple and Advanced modes The app now opens in a compact Simple mode with the core controls. Switch to Advanced mode to access per-channel gain, the console, and detailed per-effect tuning.

new Per-channel gain sliders Independent volume control for each of the four shaker channels (front-left, front-right, rear-left, rear-right). Available in Advanced mode.

new Licensing system Email-based activation with support for up to 3 machines. Free during beta.

new Window size and position remembered between sessions The app restores to the same position and mode you left it in.

Fixed

fix Engine frequency slider not responding correctly The Engine Rumble frequency slider was applying values incorrectly. Now maps accurately across the full range.

fix ABS display not clearing when off track The ABS indicator in the status panel was staying lit after leaving the track. It now clears correctly.

fix Kerb effect not zeroing when all four wheels leave the track Kerb/rumble strip feedback was continuing briefly after going fully off track. Corrected.

Initial release

new iRacing haptic engine: first release Per-corner output with ~5-19ms end-to-end latency. Six haptic effects: Road Vibration, Suspension Impact, Kerb & Rumble, Engine Rumble, ABS / Wheel Lock, Gear Change.
