Sim Racing Coach · iRacing and Le Mans Ultimate

A Sim Racing Coach
That Talks You Through the Lap.

Track Impulse is a sim racing coach for iRacing and Le Mans Ultimate. In the car it names one thing to change for the corner ahead and says it out loud. After the session it breaks the whole stint into a corner-by-corner time budget where every finding carries a cause, a target and a cost in seconds. Free during the public beta, $3 a month after.

At a glance

Coaching in the Car, Then the Full Post-Mortem.

Most coaching tools do one or the other. A live coach shouts at you and leaves nothing to study. A telemetry tool hands you charts and leaves you to work out what they mean. Track Impulse does both halves, from the same measured data, and the second half explains the first. Both are grounded in real coaching practice: the analysis rules are built on the methods professional coaches use, threshold braking, trail braking, the traction circle, the phases of a corner. Not generic stats.

In the car

A single line for the corner ahead, spoken aloud and shown on the overlay. What to change, how much, what it is worth, and how much time you have found this session. Nothing to read mid-corner.

After the session

Your whole stint, split into a time budget that adds up to your real lap delta. Every finding names the cause, gives a target and states what fixing it pays, in seconds.

Close view of the coach panel for turn 5, reading BRAKE LATER with the correction of about 15 metres later, a value of plus 0.3 seconds, and a running total of 3.2 seconds found so far in the session, above a braking distance bar reading 140 metres.
One line The instruction, the size of the correction, what it pays, and the time found so far.
01 / In the car

It Speaks. One Corner at a Time.

The live coach picks the single biggest thing you can change for the corner you are about to enter, and says it. Brake later, about 15 m, worth 0.3 s. Not a wall of numbers, not a chart to read at 180 kph. One correction, sized, priced, spoken.

It keeps score honestly. The found figure is time you have actually taken out of your lap since the coaching started, not a projection of what you might gain. The next corner sits alongside it so you know what is coming and whether you took the last one cleanly. The total keeps growing across sessions too: lifetime seconds found, kept per car and track. Real units a racer brags in, not an invented score.

  • Spoken aloud, so your eyes stay on the road
  • One instruction per corner, with the size of the correction
  • What it is worth in seconds, before you try it
  • A running total of time actually found this session
  • Target and projected lap time, live against your reference
  • Cross the line and a post-lap verdict names the single best fix for next lap, with the expected gain
  • A haptic pulse at the reference braking point, through your bass shakers

In place The whole strip as it sits on screen. Pace against your target, your pedals, the instruction, and the corner after this one.
When it speaks, and when it does not

It Knows When to Shut Up.

The fastest way to kill a live coach is to let it nag. This one knows coaching belongs in practice: in a race it is off unless you invite it. Opt in for a race and it still picks its moments. Tips are rate-limited, suppressed in battles, side by side, under yellow flags and on pit road, and advice you have already heard is not repeated. Racing comes first. Coaching fits in the gaps.

Quiet until it has evidence

It never coaches from thin air. The coach stays silent until it has three clean laps of you on record, and shows a learning indicator while it gets there. Advice built on one wobbly lap is guesswork, and guesswork is the one thing it is not allowed to say.

Except at a brand new track

Arrive somewhere you have never driven and the new-track guide takes over first. It talks you around the opening laps corner by corner: hard braking, light braking, flat out. Once it knows your driving, it hands you to the real coach.

What coaching costs

Coaching Runs From Free
to $297 a Month.

This is a crowded category and it is worth seeing the whole of it. Live spoken coaching is no longer a premium feature. Full Grip Vision includes coaching in its free tier, and the best known paid one, trophi.ai, is $7.50 a month on its annual plan. Track Impulse Pro is $3 a month once the beta ends, and every Pro feature is free until then. Price is not the reason to pick this one, so the rest of this page is about what it actually does with your lap.

Competitor pricing checked 16 August 2026 from each product's public pages. Annual plans are shown as their per month equivalent: trophi.ai charges $89.99 a year up front and publishes no monthly rate, Coach Dave Delta is $109 a year, and Garage 61 quotes its EUR 5 only on the yearly plan. TrackPro's $20 tier meters how much coaching you get, and its $97 and $297 tiers buy five times and twenty times that allowance. Virtual Racing School has no automated voice coach, though it does sell live human coaching from $29.99 a session. Tiers change; check before you buy.

What free actually means here

Fourteen overlays are free permanently, with no account, no quotas and no trial clock: the radar spotter, relative, standings, fuel calculator, inputs dash, shift light, battle bar, live track map, session info and the pit helper among them. You never need Pro to race safely. Pro is the power tools, and every Pro feature is free for the whole public beta.

Two coach findings for turns 11 to 12, each worth 0.12 seconds: use about 1.0 metre more road on the exit because the reference lets the car run all the way out, and squeeze the throttle once out of the corner instead of lifting 3 times where the reference lifts none, taking a touch less speed in if the car feels loose.
Cause Same corner, two different causes. One is the road you are leaving unused, the other is three lifts where the reference had none.
Two coach findings for turns 1 to 2: get to full throttle 1.7 seconds sooner because corner speed is fine and the exit is where it costs, reaching full power in 1.8 seconds against the reference's 0.2 seconds, worth 0.07 seconds; and brake harder because you peak at 64 percent pedal against the reference's 82 percent, worth 0.03 seconds.
Numbers Every sentence carries the figures behind it. 64% peak pedal against a reference at 82%.
02 / The finding

It Names the Cause,
Not Just the Gap.

A lap time gives you a total. A delta trace shows you where. Neither tells you what you did wrong. The Coach names it: an exit left slow, a brake you never fully commit to, three lifts where the reference had none, road left unused on the way out, turning in too early and running out of track, a front that is scrubbing, coasting between the pedals.

One cause, one instruction, one number. Nothing ships without a target, so you always know what to change and by how much. Get to full throttle 1.7 s sooner. Brake harder, you peak at 64%, the reference at 82%. You can go and drive that.

"Use about 1.0 m more road on the exit of T11-12: the reference lets the car run all the way out. Worth about 0.12 s"

"Squeeze the throttle once out of T11-12 instead of lifting 3 times (reference lifts 0); if the car feels loose on exit, take a touch less speed in. Worth about 0.12 s"

Real output, iRacing, Toyota GR86 at Oschersleben
The coach header for lap 6 at 1:37.016 against a personal best: this lap is 0.55 seconds off, split into turns 8 to 10 at 0.25, turns 4 to 7 at 0.12 and turns 11 to 12 at 0.12, with a line stating the top two findings are worth 0.23 seconds of the 0.55 second gap.
Budget The lap, the split, and how much of your gap the top findings actually account for.
03 / The time budget

A Lap Breakdown
That Actually Adds Up.

The Coach splits your lap into sections and puts a cost on each. Those costs sum to your real lap delta, to the hundredth. 0.55 s off: T8-10 costs 0.25, T4-7 costs 0.12, T11-12 costs 0.12. Nothing is hand-waved and nothing goes missing.

It prioritises for you too. One line states how much of your gap the top findings account for, so you know before you go back out whether you are chasing one big fix or five small ones. On this lap the top two are worth 0.23 s of the 0.55 s gap.

  • A cost in seconds on every corner and every straight
  • Findings ranked by what they are worth, not by turn number
  • Straight-line losses traced back to the corner that caused them
  • The same mistake across similar corners called out as one habit
The top findings strip along the bottom of the Coach tab: turns 11 to 12 worth 0.12 seconds, let the car run out to the exit kerb; turns 11 to 12 worth 0.12 seconds, one progressive throttle out of the corner; and turn 14 worth 0.08 seconds, turn in later to keep road for the exit.
Priority The three to take back out with you, phrased as something you can actually do.
The what you are doing right block: for turns 4 to 7, on full power 0.6 seconds earlier than the reference, keep that; and for turn 13, carrying 5 kph more than the reference through the corner, keep that.
Keep that Tracked separately, so a coaching session does not read as a list of everything you got wrong.
The lap list for a ten lap stint: lap 2 is the personal best at 1:36.679, laps 3 to 8 run between 1:36.716 and 1:36.789 with deltas from plus 0.04 to plus 0.11, lap 6 is selected at 1:37.016 with a share button, and laps 9 and 10 are marked invalid and greyed out.
Whole stint Ten laps read, not one. Invalid laps greyed out and excluded rather than quietly averaged in.
04 / What you already do well

It Also Tells You
What Not to Change.

Every finding has a mirror. When you are better than the reference somewhere, the Coach says so and tells you to keep it. On full power 0.6 s earlier than the reference out of T4-7. Carrying 5 kph more through T13. That matters more than it sounds: chase a lap time blind and you will often break the part you had right.

It reads your whole stint, not one lucky lap. Out-laps, in-laps, invalid laps and laps spent in traffic are excluded rather than averaged in, so the picture is of how you actually drive, not of the one lap everything landed.

Trace Every finding is checkable. The traces sit next to the sentence that came from them.
05 / The evidence

Measured Telemetry.
Not a Guess.

This is not a prediction engine and it does not invent advice. Every sentence comes from numbers taken off laps you actually drove, which is why each one carries its figures and why the corner costs sum to your real delta. If it is not in the data, the Coach cannot say it.

That is also why the evidence sits right there. The track map is learnt from your own laps and coloured by pedal input. The speed, pedal and delta traces line up underneath. Any finding can be traced back to the moment on the lap that produced it, and any lap can be exported to CSV.

  • Recorded automatically at 60 samples a second
  • Analysis runs locally on your PC, no cloud telemetry service
  • Reference against your PB, a chosen lap, or a community lap
  • Air and track temperature shown on every reference lap
06 / The line

Where Your Line Went, Metre by Metre.

The Coach explains the lap in sentences. The Line view shows it in geometry: your lap against the reference, drawn on the real circuit, with the gap between them measured at any point you hover. 2.4 m right of PB is a different problem from braking too early, and it wants a different fix.

Line Lap 2 against the PB at Oschersleben, coloured by speed. The tooltip measures the gap between the two lines wherever you point.

Readout Speed, pedals, steering, lateral G, gear, revs and delta at whatever point on the lap you are looking at.
Felt, not just heard

The Only Coach That Talks
Through Your Bass Shakers.

Track Impulse is haptics software first, and the coach uses that. It can mark the reference braking point with a pulse through your rig, so the brake later you just heard becomes a point you feel arrive. A haptic cue at the braking point is something no audio-only coach can copy.

And if you bought Track Impulse for the shakers, the coach costs you nothing where it matters: it runs in a separate process, completely off the haptic engine's audio path. Your effects still arrive in as low as 2ms, coached or not.

Sim support

Which Sims the Coach Works In.

Coaching needs telemetry channels that not every sim publishes. iRacing and Le Mans Ultimate give the Coach everything it needs, and both get the full thing. The overlays and the haptic engine cover far more, so the app is still worth installing for a sim the Coach cannot read yet.

FAQ

Sim Racing Coaching:
Common Questions.

Is this AI coaching?
The word is doing a lot of work in this category. Almost every coaching tool on the market, this one included, is algorithms reading telemetry, and live coaching in particular leaves no room for a round trip to a language model between one corner and the next. So the label tells you very little. What tells you something is whether the output is checkable. Every finding here carries the figures it came from, and the corner costs sum to your real lap delta. Nothing gets said that the telemetry does not support.
Does it actually talk to you while you drive?
Yes. The live coach names one change for the corner ahead and speaks it aloud, with the size of the correction and what it is worth. It also shows a running total of the time you have found so far in the session. Several tools now do live coaching, and Full Grip Vision has a free entry tier, so it is worth trying a few before you settle. The thing this one will not do is fill silence with advice it cannot back: if the telemetry has nothing specific to say about the corner ahead, it says nothing. It also knows its place. In a race the coach is off unless you opt in, and even when you do, tips are suppressed in battles, side by side, under yellow flags and on pit road, and it stops repeating advice you have already heard.
Which sims does the coaching work with?
iRacing and Le Mans Ultimate. Both get the full thing: live coaching, every lap recorded and the whole post-session breakdown. Each sim keeps its own lap history. The overlays and the haptic engine cover twelve sims, but coaching needs telemetry channels the others do not publish yet.
How much does it cost?
The Coach is an Overlays Pro feature, and every Pro feature is free for the whole public beta. After the beta Pro is $3 a month, subscription only, cancel anytime. Fourteen overlays stay free permanently, so you never need Pro to race safely. See the overlay pricing.
Do I need to start a recording?
No. There is nothing to start, stop, configure or export. Run iRacing or Le Mans Ultimate and every lap is captured while you drive, practice, qualifying and race alike. Open Performance Review afterwards and the whole stint is already there.
What happens at a track I have never driven?
The new-track guide takes over. It talks you around the opening laps corner by corner, hard braking, light braking or flat out, so you learn the circuit without alt-tabbing to a track guide video. Once it has three clean laps of your own driving on record, it hands you to the real coach and the advice becomes about how you drive, not generic.
Does the coach affect my haptic latency?
No. The coach runs in a separate process, completely off the haptic engine's audio path, so it has zero impact on your bass shaker effects. They still arrive in as low as 2ms whether the coach is speaking or not. The coach can also use the shakers itself: a haptic pulse at the reference braking point, felt through the rig, which no audio-only coach can copy.
Does my telemetry get uploaded?
No. Your laps stay on your own PC and the analysis runs locally. There is no cloud telemetry service and no monthly fee to look at your own driving. The internet is only used if you choose to download or share community laps, which is opt-in and anonymous by default.
What can I compare against?
Your own personal best, any lap you select, or a community lap shared by another driver. Community laps arrive with their full telemetry trace rather than just a time, and each one shows its date, air and track temperature so you can judge whether the conditions were comparable. You can browse every shared community lap before you install anything.
I can already read my own telemetry. Is this still worth it?
This is the fair criticism of the whole category, so it deserves a straight answer. The charge is that a coach stops helping the moment you can read a brake trace yourself, and that free telemetry tools cover the rest. Reading traces is exactly what the post-session view automates. It prices every corner against your reference and the costs sum to your real lap delta, so the answer to where the lap time went arrives in seconds instead of an evening. If you enjoy the evening, every trace is there and any lap exports to CSV. If you would rather have the answer and go again, that is what this is for.
Will it tell me about every corner, or just a couple?
Every corner, every lap. The common complaint about coaching tools is being handed a tenth in two corners while still sitting most of a second off the reference, with nothing to explain the rest. The time budget is built so that cannot happen: every corner carries a cost in seconds, and those costs add up to the delta you actually drove. If a corner is not losing you time, it says so.
Does it do setups?
No, and it is worth saying plainly rather than letting you find out. The coach works on driving: where you brake, how you release it, where you get back to throttle and what each of those is costing. Some rivals do offer setup advice. If that is what you need, they are the better buy today.
Is it a replacement for a human coach?
For finding lap time, it does the job a data engineer would do, on every lap, for $3 a month. What it does not do is racecraft, strategy under pressure, or reading a situation the telemetry cannot see. A human coach is still better at those, and considerably more expensive.
Can I get the data out?
Yes. Any lap exports to CSV, and the window copies to an image in one click for sharing a finding in Discord or a forum thread.
