01 / Radar Spotter

The iRacing Radar Spotter:
Eyes On Your Blind Spots.

The Track Impulse radar spotter is a visual proximity overlay, an iRacing radar for the cars you cannot see, available in three modes. The disc view puts your car at the centre of a circular radar and places every nearby car by bearing and distance, blue when far, amber when close, red and pulsing when you are door to door. Works in iRacing, Le Mans Ultimate, Assetto Corsa EVO and Automobilista 2.

Prefer a different read? The side bars alongside it are the minimal view: one slim bar per side, a capsule sliding along it for each car, red with a pulsing rim when you are door to door and an amber chevron at the foot when someone is closing from behind. There is also a portrait radar with the cars in a fore and aft lane. All three views clear the instant the car drops back. Built for single-screen rigs where you have no mirrors. The iRacing radar page covers all three, the metre thresholds and how it compares in depth.

  • Disc, portrait radar or simple two-bar view
  • Lights up the moment a car is alongside
  • Blue to amber to red by how close it is
  • Built for single-screen rigs with no mirrors
02 / Dashboard

The Dashboard Overlay:
Your Whole Car, One Cluster.New

The Track Impulse dashboard overlay is a full sim racing instrument cluster in one panel, free in iRacing, ACC, Assetto Corsa, Le Mans Ultimate and every sim the app supports. The same 300 degree tachometer sits at the heart of every design, gear, speed and revs on the hub, a needle sweeping the full arc. What changes is the shape around it. Above are three of the newest: the wide Pod, the centred Delta Wing and the tall Halo, each carrying the battle with the cars ahead and behind, live pedals and a data strip. Ten layouts ship in total. Most of the body is swappable, so a segment can hold your input trace, the learnt track map, incidents, iRating, time remaining or your position, and cells a sim cannot fill simply hide.

  • 300 degree tacho with gear, speed and revs
  • Battle strip for the cars ahead and behind
  • Live throttle and brake, plus a 5 second input trace
  • Swappable segments: track map, incidents, iRating, fuel and lap data
  • Ten layouts, each scaling from one size slider

Live in-browser preview
Close view of the Track Impulse live coach overlay 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.
The full live coach overlay strip in the car: a pace panel showing target 1:52.30, projected 1:53.88 and plus 0.78 against target, brake and throttle pedal bars, the coach panel for turn 5 reading BRAKE LATER worth 0.3 seconds with 3.2 seconds found, and a next corner panel for turn 7 marked clean at 11 of 19.
In place The whole strip on screen: pace against your target, your pedals, the call for this corner, and the one after it.
03 / Live Coach

The Live Coach Overlay:
One Call Per Corner.New

The Live Coach is an overlay that picks the single biggest thing you can change for the corner you are about to enter, and says it out loud. Brake later, about 15 m, worth 0.3 s. One instruction, sized and priced, spoken before you get there. Nothing to read at 180 kph. It runs in iRacing and Le Mans Ultimate, and it is the only live coaching panel in any overlay app.

It stays quiet until it has three clean laps of you on record, so nothing it says is a guess. In a race it is off unless you invite it, and even then it holds back in battles, side by side, under yellow and on pit road. The found counter is time you have actually taken out of your lap this session, not a projection of what you might gain, and the total carries over per car and track.

  • Spoken aloud, so your eyes stay on the road
  • One correction per corner, with its size and what it pays in seconds
  • Silent for three clean laps rather than coaching from thin air
  • A new-track guide that talks you round a circuit you have never driven
  • A haptic pulse at the reference braking point, through your bass shakers
How the sim racing coach works
The Track Impulse Performance Review window on the Coach tab in iRacing: session and lap lists on the left, ranked coach findings for T1-3, T10-11, T4, T8-9 and T7 with a cost in seconds on each, a straight losses block, a what you are doing right list, a track map coloured by throttle and brake, and speed, pedal and delta traces.
Two coach findings for Turn 10 to 11, each worth 0.12 seconds: one saying to build brake pressure faster because you take 144 metres to reach peak pressure against the reference's 39 metres, the other saying 15 percent more grip is available because your best pass pulled 1.51g against a typical 1.29g.
Cause Not just where you are slow. What you did, what to change, and what it is worth.
The coach header: typical lap 1.18 seconds off, split into T10-11 1.32, T4 0.12, T1-3 0.08 and straights 1.20, a line stating the top two findings are worth 1.18 seconds of your 1.18 second gap, and a note that 6 of 7 laps were eligible with 1 invalid.
Budget Every corner priced in seconds, and the costs sum to your real lap delta.
04 / Performance Review

The Performance Review App:
Your iRacing Telemetry, Analysed.New

Performance Review is a full iRacing lap analysis app with a driving coach built into Track Impulse, and it now works in Le Mans Ultimate as well. Every session records automatically while you drive. Open it afterwards and the stint is already broken down across nine views: speed, brake and throttle heat maps on a track layout learnt from your own laps, corner detail, lap comparison, driving line, sectors and community laps.

The Coach is the part nothing else does. It reads your whole stint rather than one lucky lap, prices every corner in seconds, and names the cause: an over-slowed entry, a slow brake build, a lazy trail brake, coasting between the pedals, grip you are not using. Every finding comes with a target and what fixing it is worth. No other overlay app has an equivalent: RaceLab and iOverlay show you the race while it happens, and stop there.

  • Every lap recorded while you drive, nothing to start or stop
  • Corner costs that add up to your real lap delta
  • Trail braking and steering corrections measured against a reference
  • Community laps with full telemetry, plus CSV export
Full Performance Review breakdown
05 / Shift Light

The iRacing Shift Light:
Upshift on Instinct, Not Guesswork.New

The Track Impulse shift light is a standalone upshift indicator you can place anywhere on screen, right in your sightline. It fills green, then amber, then red and flashes blue at the optimal upshift point, following the sim's shift rpm in iRacing, ACC, Assetto Corsa and every supported sim, or set your own shift point to suit your car or driving.

Pick the look that reads fastest for you: five styles, from a simple block, bar, ring or meter to the round Apex dial above, each with an optional gear digit. It stays independent of the other panels, so it never competes with the rest of your layout.

  • Green to red to a flashing blue at the optimal shift
  • Follows the sim's shift rpm, or set your own shift point
  • Five styles: block, gauge, ring, meter and Apex dial
  • Optional gear digit, placed anywhere you want
06 / Relative

The iRacing Relative Overlay:
Who's Coming, And How Fast.

The Track Impulse relative overlay lists the cars immediately ahead and behind you, ordered by interval in seconds rather than race position. Each row shows position, car number and class, driver name, iRating, projected iRating gain, licence, live interval, last lap pace delta, manufacturer badge, gap, last lap time and tyre compound in iRacing, with the fields a sim exposes filled automatically in ACC, Le Mans Ultimate and Automobilista 2.

Reading threats is the job. The interval turns red when a battle closes inside half a second, the manufacturer badge lights up while a car is within one second of you, and the pace delta tells you whether the car behind is actually faster or just close. Every column can be toggled and reordered, so the panel carries exactly what you glance at and nothing you do not.

  • Position, car number, driver name, iRating and licence
  • Live interval, red when a battle is inside half a second
  • Manufacturer badge that lights up inside a one second battle
  • Pace delta, projected iRating gain and tyres
  • Sorted by proximity on track, not standings
07 / Battle Bar

The Battle Bar Overlay:
The Two Gaps That Decide Your Race.New

The Track Impulse battle bar shows the only two numbers that matter wheel to wheel: the gap to the car immediately ahead and immediately behind, paired in the centre of one compact strip. Each rival gets a name, position, car number and licence, so you always know exactly who you are racing, and a proximity track across the top shows both cars closing in real time.

Choose from six layouts, from a minimal readout to the full broadcast-style bar with a last lap row comparing your pace against both rivals. Built for iRacing and Le Mans Ultimate where the gap data is exact, and it hides itself when nobody is close.

  • Live gap to the car ahead and behind
  • Driver name, position, car number and licence per rival
  • Last lap times for you and both rivals
  • Six layouts, hides when no one is near
08 / Fuel

The iRacing Fuel Calculator:
The Maths, Done For You.

The Track Impulse fuel calculator is a built-in iRacing fuel overlay that learns your per-lap burn rate over a few clean laps, then shows litres in tank, a pit window countdown in laps or minutes and exactly how much to add at the next stop, with the pit call, your lap and the fuel margin pinned in the footer. Six styles: it opens on the Apex card shown here, which has four layouts of its own, and drops back to a compact strip or the classic card if you prefer. Works in iRacing, ACC, Assetto Corsa, Le Mans Ultimate and every sim that publishes a fuel level. No SimHub plugin, no spreadsheet, no guessing the last splash. The iRacing fuel calculator page covers the burn-rate maths, the pit window and every style in depth.

  • Litres in tank and a live tank bar
  • Pit window countdown in laps or minutes
  • Per-lap burn learned from clean laps
  • Fuel to add at the stop, with your margin
09 / Standings

The iRacing Standings Overlay:
The Class Order, Leader to Last.

The Track Impulse standings overlay shows where you sit in your own car class, sorted by class position with the leader at the top. In iRacing multiclass races it splits the field into class blocks (GT3, GT4, LMP2), each with its own strength of field and the lap counter in the class band, so a GT3 driver is never lost in a field of prototypes. Also works in ACC, Le Mans Ultimate and Automobilista 2.

Your row stays pinned in view even when the order runs deeper than the panel. Each driver gets position, car number and class, name, gap to the class leader, pace delta against your last lap, best lap, iRating, licence, manufacturer badge, last lap and tyre compound, plus projected iRating change, with the class-fastest lap highlighted. Lapped cars show an amber plus one L in place of the gap, so you know who is not racing you before you commit to the move. Every column can be toggled and reordered.

  • Split by class with strength of field
  • Gap, pace delta, best and last lap per driver
  • Lapped cars flagged in amber, class-fastest lap highlighted
  • Manufacturer badges, tyre compound and projected iRating change
  • Sorted by class position, leader first
10 / Haptics

The Haptics HUD:
See What Your Bass Shakers Are Doing.

The Track Impulse haptics HUD is an on-screen meter for your bass shakers: a live level for each of your eight effects, plus the master level, moving at the same instant the shakers fire. The same install that draws your overlays also drives them. The haptic engine behind it delivers telemetry to your shakers with as low as 2ms end-to-end latency, a measured 8ms in iRacing against SimHub's 137ms.

It is the fastest way to tune your effects: drive a few laps and see whether ABS is firing under braking, whether suspension is saturating over kerbs, or whether an effect you thought was on is sitting flat. No shakers? Leave this panel off and everything else on this page works exactly the same.

11 / Twitch Bot

The iRacing Twitch Bot:
Chat Asks. The Overlay Answers.New

Every overlay app can show your chat on screen. Track Impulse is the only overlay app with a built-in interactive iRacing Twitch bot: viewers type a command, and the bot answers in chat from the same live telemetry the overlays use, within a second or two. 14 commands: !fuel, !gap, !lap, !delta, !inc, !weather, !car, !track and more, plus !ir, !sr and !sof for iRacing ratings. Wear a heart rate monitor and !hr lets chat check your pulse three wide into T1.

The chat overlay itself merges Twitch and YouTube into one read-only feed over the sim, with a Featured card to pin a message on screen. Standalone chat bots for iRacing exist, but they are a second app to install and run. Here the bot lives inside the overlays: one install, next to your radar and relative.

  • 14 commands answered from live telemetry: !fuel, !gap, !sof, !sr and more
  • !hr reads your heart rate monitor live
  • Merged Twitch and YouTube chat feed with a Featured pin card
  • Built into the overlay app, no separate bot to run
Every overlay

All Your Overlays,

Customisable layout

Put Every Panel
Exactly Where You Want It.

Drag any panel anywhere, then lock the layout with a single key so nothing moves once you are racing. A banner on each panel tells you whether you are in edit or locked mode.

Drag and lock

Drag any panel into position, then press F6 to lock the layout. Each panel shows a banner confirming edit or locked mode.

Show when it matters

Set each panel to show in the car, out of the car, or always. Keep the relative up only while driving, or pin the session strip everywhere.

Header & footer strips

Add subtle header and footer strips with track and session info, for context without a separate overlay slot.

Per-panel opacity

Tune background colour, opacity and content opacity per panel. Almost invisible until needed, or solid enough to read at a glance.

One settings window

Everything lives in a single tabbed Settings window. One place to switch panels on and off and adjust appearance.

Ultrawide friendly

Wide horizontal layouts that suit the top or bottom edge of an ultrawide or standard display, out of your sightline.

Starts in your language

A language picker appears the first time you launch the overlay app, so it starts in your preferred language. You can change it later from Settings with a quick restart.

Supported sims

iRacing, ACC and Assetto Corsa Overlays
Plus Nine More Sims.

Track Impulse Overlays run in thirteen sims: iRacing, Le Mans Ultimate, Assetto Corsa Competizione, Assetto Corsa, Assetto Corsa EVO, Assetto Corsa Rally, Automobilista 2, RaceRoom, F1 25, Euro Truck Simulator 2, BeamNG.drive, EA Sports WRC and DiRT Rally 2.0. The app detects which one you are running and switches automatically. Outside a supported sim the overlays stay hidden.

Three columns below are deliberately short. F1 25 publishes far less about a session than the circuit sims, so most of its column is a No. EA Sports WRC and DiRT Rally 2.0 are stage rally: one car alone, point to point, no roster and no lap that wraps, so the radar, relative, standings, battle bar and delta trace have nothing to read there. Both do publish a real rev limit and the car's own shift band, so the dashboard and shift light work properly.

Below is a table of which overlays are supported in which sim. For the two biggest Assetto Corsa audiences there are dedicated pages: the ACC overlays page covers every panel Assetto Corsa Competizione supports, and the Assetto Corsa overlays page covers AC, AC EVO and AC Rally.

Thirteen columns will not fit on a phone. Pick the sims you want to compare.

Prices and features checked from each vendor's own site on 16 August 2026. Free tiers and paid plans change, so confirm at the source before you buy. RaceLab also sells a EUR 49.90 yearly plan and a EUR 399 lifetime licence, and its own site counts 7 sims even though 8 logos appear on it. SimHub's licence is a one-time pay what you want with EUR 8 the lowest amount offered, and the free version's 10 fps cap applies to shaker output as well as dashboards. RaceLab does not publish which overlays sit in its free tier, so its rows say Yes where the overlay exists rather than guessing a tier. Cells marked Not listed could not be confirmed from the vendor's site. SimHub also drives bass shakers, so the difference there is low latency and the live haptics HUD, not haptics on their own.

Everything is free during the public beta, Pro included, so you can use the whole suite before deciding. The haptics beta ends on 19 September 2026, but the overlays beta keeps running past that date: we will give notice well before Pro needs a subscription. Bought the haptic engine during the beta? Your included 6 months of Pro start when the overlays beta ends, so you always get the full 6 months of paid Pro. Pro features are marked with a PRO chip in the app. There is no perpetual overlay licence: the free tier is genuinely free and stays that way, and Pro is a subscription that pays for the coaching engine behind it.

FAQ

iRacing Overlays:
Common Questions.

Are Track Impulse overlays free?
Yes. 14 overlays are free permanently, including the radar spotter, relative, fuel calculator, standings, inputs dash, shift light, track map and battle bar. No account, no quotas, no trial clock. Pro adds the power tools: Performance Review, the live Coach, pit strategy, delta trace, the race recap card and the streaming suite. Pro is $3 a month, and every Pro feature is free during the public beta.
Do I need an account to use the overlays?
No. There is no account to create and nothing to sign in to. A free license is set up automatically the first time you run the app, tied to your machine, and checked quietly each time it starts. Download, install, race.
Which sims do the overlays work in?
Thirteen sims: iRacing, Le Mans Ultimate, ACC, Assetto Corsa, AC EVO, AC Rally, Automobilista 2, RaceRoom, F1 25, Euro Truck Simulator 2, BeamNG.drive, EA Sports WRC and DiRT Rally 2.0. The app detects which one you are running and switches automatically. The per-sim table answers this as a straight yes or no for every overlay in every sim: if it runs and does its job there, it is a Yes. Not every sim publishes what iRacing does, so where a sim publishes nothing for a field the panel reads N/A instead of a made-up number, and an overlay a sim cannot feed at all is a No and says Not available on this sim on screen. You are never left guessing whether it is the sim or the app.
Do I need a bass shaker to use the overlays?
No. The radar spotter, relative, standings, fuel calculator and session overlays all work on their own. The haptics HUD is the only panel that needs bass shakers, and it simply stays idle if you do not have any.
What is the haptics HUD?
A live overlay that reads straight from Track Impulse and shows a level meter for every bass shaker effect the instant it fires: road, suspension, kerb, engine, ABS, gear change and wheel slip. It is the fastest way to see and tune your effects by eye.
Do the overlays work on every screen type?
The overlays are built for single screen and triple screen setups, including ultrawides. The wide horizontal panels suit the top or bottom edge of a display, out of your sightline, and the radar spotter is built for rigs with no mirrors. VR support is not there yet: the panels draw on your monitor, not inside the headset.
Do the overlays work in fullscreen?
Run your sim in borderless (sometimes listed as borderless windowed) or windowed mode. In exclusive fullscreen the sim takes direct control of the display through DirectX and Windows stops compositing other windows over it, so nothing can draw on top. The overlays keep running, they just stay hidden. Every supported sim has the setting in its video options, and this is the same requirement as every other overlay app.
Will the overlays cost me frame rate?
They are built to stay off your sim's frame time. Each panel runs at its own refresh rate rather than one loop repainting everything, and a panel only redraws when the data behind it changes, so a fuel readout that moves once a lap is never being repainted at monitor refresh alongside the radar.
What is Performance Review?
It is the lap analysis app and driving coach that ships with the overlays, covering iRacing and Le Mans Ultimate. Every lap records automatically while you drive, then nine views break the stint down: speed, brake and throttle heat maps, corner detail, lap comparison, driving line, sectors, community laps and the Coach. The Coach prices each corner in seconds, names the cause and gives you a target. It is a Pro feature, free during the public beta. See the full breakdown.
Is there a live coaching overlay for iRacing?
Yes. The Live Coach overlay picks one correction for the corner you are about to enter and speaks it aloud, with the size of the change and what it pays in seconds. It covers iRacing and Le Mans Ultimate, stays silent until it has three clean laps of you on record, and switches itself off in a race unless you invite it. No other overlay app has one. It is a Pro feature, free during the public beta. How the coach works.
Do I need SimHub for iRacing overlays?
No. Track Impulse overlays run on their own: no SimHub, no plugins, no dashboard building. Every panel ships ready to use, from the radar spotter to the fuel calculator. SimHub builds its overlays from community dashboards you assemble yourself; here you tick a box during install and race.
Is there an iRacing Twitch bot in the overlays?
Yes. Track Impulse is the only overlay app with a built-in interactive Twitch bot. Viewers type one of 14 commands, !fuel, !gap, !sof, !sr, !hr and more, and the bot answers in chat from live telemetry within a second or two. Other overlay apps only display chat; standalone bots exist but are a second install. The bot is part of the Pro streaming suite, free during the public beta.
What are the best free iRacing overlays?
Track Impulse has 14 free overlays, and 12 of them run in iRacing: a radar spotter, relative, standings, a fuel calculator, a full inputs dashboard, a shift light, a battle bar, session info, a live track map, a pit helper, a privacy cover and a live haptics HUD. The other two free panels, energy and stint, are Le Mans Ultimate only, which is the whole difference between the two numbers. All fourteen are free permanently, with no account. That is more free overlays than iOverlay, which puts its radar behind Pro. No SimHub required. They also work in ACC, Assetto Corsa, Automobilista 2 and more.
