Understeer Oversteer Neutral

Understeer: the front pushes Turn-in · slow (up to ~100 km/h) 4 of 4 corners · Ø 3.15°

The front builds up its cornering force too slowly. This is a transient event: dampers and the anti-roll bar are the right tool here, not the wing.

Side effect · Front anti-roll bar softer: More roll at the front; the front gets softer in mid-corner as well.

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.

A brake beep just before the reference brake point, timed from your current speed, so your eyes stay on the road.

Scales with your screen. Drag any overlay to the size you want, it keeps its proportions.

Live Coach Le Mans Ultimate · BMW M Hybrid · Spa

Two of your own laps at Spa, 0.044 s apart over the lap, replayed at real speed. The brake point bar counts down to the reference brake point and swings through zero where the reference brakes. The other bars follow through the corner, just as in the car.

All overlays, sim by sim

Telemetry cloud

Telemetry that does the work for you.

There is nothing to set up and no worksheet to build. Drive, and the lap arrives in the cloud already analysed and explained, ready for your questions.

Nothing to set up

Install the desktop app and drive. Every lap uploads by itself, with its setup attached.

62 views, each one explained

Balance, brakes, tyres, aero, engine and more, ready before you open the lap. An engineer panel next to each says what it shows.

AI when you want it

Ask the AI chat about what is on screen, or let it analyse up to twelve laps with their setups. Priced in Fuel before you start.

Open this lap yourself

The viewer with a real Spa lap: balance and dynamics, and next to it the engineer panel explaining the view

The viewer as it is: a real lap at Spa in the balance view, and next to it the engineer panel with this lap's results, the theory and where to go in the setup.

All 62 views

47 views work with every sim. 15 more open only where the sim sends the data for them: 8 for F1, 5 for Le Mans Ultimate and 2 for iRacing. Which of the 47 fill depends on your sim and, within it, on the car. Views marked “single lap” show one lap at a time. We keep developing the views and adding new ones.

AI analysis

AI analysis Silverstone · BMW M4 GT3 · 0.32 s apart

Only your lap understeers Both laps understeer Only the reference

Same setup, same day. Where you stop trailing, the car stops turning.

Two of your own laps, 0.32 s apart, same car, same setup, same conditions. So any change in the balance can only come from your inputs. Pick a finding to see it on the map and in the data.

The rest of the lap gives about 0.07 s back.

Your lap Your best lap 3560–3960 m

Do this first: into the corner at 3.7 km, brake as hard as on your best lap and hold the pedal about 10 m longer into the turn-in, so the car rotates. Target 135 km/h at the apex. About 0.2 s.

AI analysis · the driver

What you do differently, and what it does to the car.

It compares your inputs with the lap you are chasing and shows where they change the balance: where you make the car understeer, and where the car is simply like that.

With numbers. Every finding comes with the metre, the degree or the second behind it.

Every factor, on purpose. Same setup? Then a different balance almost certainly comes from the driver. The AI checks setup, conditions and inputs first, then shows what the drivers do differently with the car, and where one of them provokes rotation and the other does not.

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. You set up each sim only once.

Download the desktop app

One file, every supported sim included. Unzip it somewhere permanent, start it, sign in with the same account. From then on it updates itself.

Windows 10 / 11

Point it at your sim

The desktop app finds the game by itself. For Le Mans Ultimate and rFactor 2 it installs our telemetry plugin on its first start and keeps it up to date: start it once with the game closed. Automobilista 2 and F1 need one switch in the game, and the desktop app shows you which. ACC and Assetto Corsa need nothing.

Choose Factory

A seat is one member of your team. On Rookie, Clubsport and Pro each member needs a plan of their own. Factory includes the licences. A channel is a shared team folder with its own chat. 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, and what it pays for

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 pay what it actually used, never more than that number.

A question to the AI chat in the viewer, priced the same way, per message.

Opening a lap somebody else drove costs 0.01 Fuel, once. After that it is yours and opening it again is free.

A setup or a reference lap from the shop costs 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 come with the plan.

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.

Servers take the upload, process it and hand the lap back, usually before you are out of the car.

Your plan fills your monthly tank with 15, 30 or 60 Fuel. It is used first, and what is left runs out at the end of the month. You can refuel at any time on top: a top-up from €4.99 for 4 Fuel up to €49.99 for 56 goes into your reserve tank. The reserve never expires, and you can fill it up again whenever you like.

FAQ

Questions, answered.

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?

iRacing, Le Mans Ultimate, rFactor 2, Automobilista 2, F1, Assetto Corsa and Assetto Corsa Competizione. More are coming.

Can I try it without paying?

Yes. The free plan needs no card and keeps 10 of your own uploads a month. On top you get 14 days of the live coaches and the full viewer, counted from your first use.

Does it run on a Mac?

The viewer runs in any browser. The desktop app that records your laps needs Windows 10 or 11, the same machine your sim runs on.

Do I need to install a plugin?

Not by hand. For Le Mans Ultimate and rFactor 2 the desktop app installs our telemetry plugin on its first start and keeps it up to date. Start it once with the game closed. Automobilista 2 and F1 need one switch in the game, and the desktop app shows you which. ACC and Assetto Corsa need nothing.

What is Fuel?

The credit for AI analyses and for unlocking setups, data and reference laps. Your plan includes 15, 30 or 60 Fuel a month, and you always see the price before you spend it. Your own laps never cost Fuel. More on plans and Fuel

Can I cancel any time?

Yes, in your account under Manage subscription. The plan runs to the end of the period you paid for. The free plan has nothing to cancel.

How do teams work?

Every paid plan includes a team: Rookie 2 seats, Clubsport 3, Pro 5. Each member needs their own plan. Factory includes 10 user licences, so your members need no plan of their own.

Who can see my laps?

You decide for every lap. A private lap is visible only to you. You can put it in your team's folders, and you can share it with the community, where other drivers can open it.

How does a setup get into my sim?

You unlock it in the app, and it installs itself into the right folder. No copying files around.

I bought setups in the old shop. Where are they?

Your account has moved with us, and the rFactor 2 setups you bought are already unlocked: sign in and find them under My purchases. The old Le Mans Ultimate setups are out of date after the game's updates. If you still want one, write to us.

What does coaching cost?

€50 for one hour, €90 for two, €130 for three, with experienced sim racers from our own community. See coaching
