Every line on this page is a lap somebody drove.

The map above and the trace below come from one reference lap in the platform. Same data the app works with, same numbers you get back after your own lap.

A race engineer in every view

Worksheets, channels, multi-lap overlays, track map, delta. Every view explains the physics behind it: balance, braking, rotation, racing line, and the technical channels too — aero maps, suspension, tyre, engine, transmission. What you are looking at, why it matters, what to read from it.

Every tenth, explained

Cloud AI reads every physics channel of your lap and understands how the car behaved through each corner. Not "you lost three tenths in Turn 4" but why: entry understeer, throttle too early, a rotation you never got.

Every lap in the cloud, by itself

Cross the line and the lap uploads on its own — telemetry, setup, lap time, history. The setup is linked to the lap that ran it, so two runs compare one to one. No exporting, no folders.

What nobody else does

It reads the car, not just the driver.

Every tool tells you where you lost time. This one measures what the car did while you lost it, then names the setting to change and what it costs you elsewhere.

Out of your own lap — slip angle front against rear, corner by corner, split by phase.
Where and when decides what helps — slow corners are mechanical, fast ones aerodynamic, dampers act only in the transitions.
Every change names its side effect, so you know the trade before you drive it.

The front axle builds its lateral force too slowly. This is a transient, so dampers and the anti-roll bar are the right tool here — not the wing.

Front toe more0.05° toe-out ●●○Geometry
Side effect of the first one: more roll at the front, and the nose goes softer in the steady part of the corner too.

Change one setting per run, or you will not know which one worked.

AI analysis 2 laps · Barcelona · 0.56 s apart
The lighter car was the slower one.

Lap 2 loses 0.56 s while carrying about 52 kg less fuel. At a rule of thumb of 0.03 s per kg that is 1.3 to 1.8 s of advantage it never used.

Where it went S6, S8, S7, S2 — more understeer, balance +1.41 and +1.12 against 0.16
Brake points 3370 m against 3372 m, both at 100 % — 52 kg lighter and still not later
Do this first: front toe towards −0.117° and firmer front damping, target a balance under 0.5 instead of 1.1 to 1.4. Potential 0.15 to 0.20 s.

It reads every channel, the setup that ran the lap and the conditions. You see the price in Fuel before it starts.

Every tenth, explained

An engineer that read all of it.

Point it at up to twelve laps. It goes through every physics channel, the setup that ran them and the conditions, then writes what happened and what to do about it.

It finds what you would not look for. The example on the left is real: a fuel difference that turned the whole comparison around.
Numbers, not adjectives — every claim carries the metre, the degree or the second it came from.
It says when it is guessing. A rule of thumb is marked as one, not sold as a measurement.
More than one driver

The whole team sees the lap, not the story about it.

Telemetry, setups, reference laps and analyses in shared channels. The moment a teammate crosses the line you can open their lap and go through it together.

The setup travels with the lap, so two runs compare one to one instead of from memory.
One team setup loads itself into every member's sim — no files, no folders, no wrong version.
Factory gives ten licences — every member gets full access without a plan of their own.

While you drive

Live Coaches

On-screen overlays compare you to your reference lap in real time and tell you what to change in the next corner, not after the session.

Brake point and brake pressure against the lap you are chasing, metre by metre.
Trail-brake distance, apex speed, exit speed as single numbers you can act on.
Engineer overlays with live under- and oversteer, so setup work stops being guesswork.
Scales with your screen — drag any overlay to the size you want, it keeps its proportions.

Race tools

Save fuel without losing the lap

Endurance racing is won on strategy. The tools compute the points from your own reference lap, then tell you in the car when to act.

Lift & Coast — where to lift for a given saving, with a countdown and a tone in the car.
Push-to-Pass maximiser — where the boost buys the most time over a lap, worked out from your telemetry.
Strategy calculator — stints, fuel and pit windows from laps you actually drove.

Both laps are real and sit in the platform. The two onboard videos run above this trace, on the same metre.

Picture and data

Two laps, one tenth, and you can see where it went.

Your onboard next to the lap you are chasing, locked to the same point on track — with the telemetry underneath, so the picture and the numbers always show the same metre.

Mark start and finish once — from then on both videos follow the lap, not the clock.
Different lap times stay in step — the slower lap runs at the ratio of the two speeds, so the corners line up.
Scrub by distance or by time, and the trace, the gap and both pictures move together.
Any two laps — two of your own runs, or your lap against a reference lap from the shop.

The two laps above are 0.122 s apart. Same top speed, but B brakes 7 m earlier into the corner at 600 m and is 13 km/h slower at the apex. The video shows what the driver did there.

Real life racing

It did not start in a simulator.

We spent the 2023 season in the Porsche Sprint Challenge paddock: coaching drivers at the track and on the simulator between events, and reading the telemetry between runs. Same questions as here, on a car that gets hot.

Driver coaching at the circuit — debrief after every run, and preparation on the simulator before the weekend.
Telemetry in MoTeC — brakes, tyres, balance, corner by corner, between sessions and against the reference.
The worksheets in this platform are those worksheets. What we built for ourselves on race weekends is what the app now does for your laps.

Track work and simulator work are the same job done twice: the simulator is where the lap is cheap, the circuit is where it counts.

One to one

Or let somebody look at it with you.

Book a session and we go through your own laps: where the time is, what the car is doing, what to change first. You keep the recording and the notes.

Getting started

Four steps to your first lap.

No hardware, no wiring, nothing to configure by hand. About ten minutes from here to your own lap open in the browser — and the sim setup happens once, not every time.

Create your account

An email address and a password. No card, nothing to cancel. Your 14 days of full access start with your first lap, not with the sign-up — so nothing runs out while you are still installing.

1 minute

Download the app

One file, all six sims included. Unzip it somewhere permanent, start it, sign in with the same account. From then on it updates itself — you never download it again.

288 MB · Windows 10 / 11

Point it at your sim

The app finds the game by itself. Le Mans Ultimate and rFactor 2 need our telemetry plugin — one click puts it in the right folder. Where the sim needs a switch flipped instead, you get the exact menu path for it.

2 minutes, once per sim

Drive

The coach talks to you while you drive. Cross the line and the lap uploads on its own, with its setup attached. Open it in the browser and the findings are already there.

Fuel is the credit for AI analyses and for unlocking setups, data and reference laps. Quarterly and yearly billing are in the app. Bigger team, or something that does not fit these four? Tell us what you need and we will put an offer together.

What Fuel is

You see the price before you spend it.

Fuel is the credit for the things that cost us money every single time they run. Your plan brings a tank each month, you can top it up, and 4 to 6 % comes back to you as points.

What it pays for

An AI analysis over up to twelve laps. The maximum price is on the button before you start, and you are billed what it actually used — never more than that number.
A question to the coach in the viewer, priced the same way, per message.
Opening a lap somebody else drove — 0.01 Fuel, once. After that it is yours and opening it again is free.
A setup or a reference lap from the shop — 3.99 Fuel, and a share of it goes to the creator who built it.

What never costs Fuel

Your own laps. Recording, uploading, opening, comparing, as often as you like.
Everything your team shares with you in a channel.
The viewer, the desktop app and every update — they come with the plan, not out of the tank.
Anything you already unlocked. You never pay twice for the same thing.

Why it costs anything

An analysis is a real call to a model, billed to us per token, every time somebody presses the button.
Every lap is a file we keep — about 1.2 MB each, stored and served for as long as you want it.
The desktop app is signed, so Windows trusts it instead of warning about it. That certificate is a yearly bill.
Servers take the upload, process it and hand the lap back, usually before you are out of the car.

A tank is €4.99 for 4 Fuel, up to €49.99 for 56. Your plan already includes 15, 30 or 60 Fuel every month, which is the cheaper way round. Monthly Fuel runs out at the end of the month; what you top up yourself stays in the reserve.

Before you ask

The three questions everyone has.

Do I have to export anything?

No. The desktop app sits next to your sim, records the lap and uploads it when you cross the line. The setup goes with it, linked to that exact lap.

Which sims work today?

Le Mans Ultimate, rFactor 2, Automobilista 2, F1, Assetto Corsa and Assetto Corsa Competizione. More are coming; the recorder is built so a new sim is an adapter, not a rewrite.

Can I try it without paying?

Yes. Open the viewer with a demo lap, no card. The free plan keeps ten of your own uploads a month, which is enough to see whether the analysis tells you something you did not know.
