Find your missing seconds.

RaceIQ captures telemetry from your sim, records every lap to a database on your own PC, and shows you the corner where the time actually went — then keeps every lap you've driven, so the gains are something you can watch accumulate.

Supported games

Four sims today. More when the keys land.

RaceIQ reads UDP telemetry and shared memory. If a game exposes an open stream, it can be supported — and the ones that aren't yet are blocked on access, not on interest.

Companion tool

What it does

Every tool a driver coach would use, on your desk.

Live dashboards, automatic lap and corner detection, side-by-side comparison, setups you can actually validate, and a catalogue of every car and circuit in the game.

AnalyseAuto cornersInsights · 12

Corner-by-corner lap analysis.

Scrub throttle, brake, steering, speed and G-force traces with automatic lap and corner detection. Every corner gets its own row, its own delta, and its own verdict — so "I lose it somewhere in sector two" becomes a turn number.

RaceIQ lap analysis: speed, throttle and brake traces stacked above a corner-by-corner breakdown table with per-corner time deltas.

LiveCombo dash

Real-time dashboards.

Speed, RPM, inputs, tyre temperature and wear, fuel, pit window and sector timing — rendered as you drive.

RaceIQ combo dashboard with a 3D car wireframe, per-corner tyre temperatures, steering trace and live sector times.

ExperimentsSetup ranges

Setups, and proof they work.

Browse tunes, see the setting ranges quick drivers converge on, then run Experiments — structured A/B tests that tell you whether a gain is real or whether you just strung together a good lap.

RaceIQ setup ranges view showing horizontal range bars for each vehicle setting, marking where the fastest recorded setups cluster.

Auto-map

Every circuit, mapped.

Bundled outlines, sector boundaries and named corners. Anything missing maps itself as you drive it.

RaceIQ track browser showing bundled circuit outlines with curated corner names.

Lap comparison · interactive

See exactly where you're losing time.

Overlay any two laps. Speed, inputs and cumulative delta aligned by distance — not by time, which is what makes a comparison meaningful once the laps diverge. Scrub the trace below; it's real telemetry.

Position

32% of lap

Drag the trace, or use the arrow keys. Corners are detected from the braking events in the trace itself, numbered from the line. Lap 3 wins most of them — but not all of them, which is exactly the kind of thing a lap time alone will never tell you.

Driver progression

Every lap you have ever driven, still on your machine.

Most telemetry tools show you one lap. RaceIQ keeps all of them. Personal bests are marked as they happen, the session recap tells you what pace and consistency you actually held, and the heatmap builds a picture of your driving over weeks. The tenth session is worth more than the first, because it has nine to measure against.

AI coaching

Send a lap to the model of your choice — cloud or fully local. The analysis is grounded in your actual telemetry, not in generic driving advice.

Lap analysis · chat

Ollama · local

Compare this lap against my personal best. Where am I losing time?

Three losses. Les Combes (+0.089s): you brake 14 m later and carry 6 km/h more to the apex, but stay flat for another 0.42 s past the clipping point. Earlier apex, throttle on before the kerb.

And the tyres?

Front-left core hit 103 °C on lap 3, past the grip-drop cliff. Take 0.4 psi out of the fronts or pull 0.1° of toe-out.

Questions

Straight answers.

Track Titan, Coach Dave Delta, Sim Racing Telemetry, Racing View are good products aimed at the same job. The difference here is the economics: free, open source, and it runs entirely on your machine.

Read the source

Is it actually free, or free-with-an-asterisk?

Actually free. No licence, no subscription, no feature gate, no account. The source is AGPL-3.0 on GitHub and you can read every line. The only thing that ever costs money is an optional AI API key, and you can avoid that too by running a local model.

Does my telemetry leave my machine?

No. Telemetry is read on your PC and written to a SQLite database on your PC. No account, no sync, no analytics. The one exception is deliberate and opt-in: if you send a lap for AI coaching, that lap goes to whichever provider you configured — or nowhere at all, if you point it at Ollama or LM Studio running locally.

Do I need an AI key to get value out of it?

No. Live dashboards, lap and corner analysis, comparison, session recap, the car and track catalogues, setups and Experiments all work with no key configured. AI coaching is one feature among many.

Mac or Linux?

Not today. RaceIQ is a Windows application — the installer targets Windows and the shared-memory readers for ACC and AC Evo are Windows-specific. Pretending otherwise would just waste your download.

I play on console. Can I use it?

Yes, if you have a Windows PC on the same network. Forza and F1 will send UDP telemetry to an IP you nominate, so point the console at the PC running RaceIQ. Wired ethernet at both ends — wireless drops packets and puts holes in the traces.

My wheelbase already receives the telemetry feed. Will this conflict?

It can, since a game generally sends its UDP stream to one destination. The UDP Forwarder companion tool takes that single stream and fans it out, so your wheelbase software and RaceIQ both get it.

How stable is it? It says alpha.

It says alpha because it is alpha. It is used daily and updates itself in place, so you stay current without doing anything — but expect rough edges and expect things to move. The Discord is the fastest route to a fix.

Install · Windows 10 and 11

Ready to get faster?

Install RaceIQ, point your game's telemetry at 127.0.0.1:5301, and start a session. It records from the first green flag.
