01Telemetry
See exactly what you did
Speed, throttle, brake and gear laid out against distance round the lap. Every braking point, every lift and every gear change is right there on the graph.
- Hover for the exact value at any point on the lap
- Scroll to zoom into one corner, drag to move along the lap
- Hide, re-order and resize graphs to suit you
02Racing line
Follow the car round the track
Your line from above, coloured from slow red to fast blue, so a corner taken too cautiously stands out at a glance. The map and the graphs are linked: point at either one and the other follows.
- Hover a graph and a marker finds the car on the map
- Hover the map and the graphs jump to that spot
- Zoom the graphs and the map lights up that stretch
03Compare laps
Find the tenths
Tick a second lap and it is laid over your main lap, dashed. The time delta shows exactly where you gain and where you lose, corner by corner, instead of leaving you to guess from two lap times.
- A time delta graph shows the gap growing and shrinking
- Every graph and the map show both laps together
- Tick any other lap to swap the comparison
04Tires
Look after your tires
Temperature, pressure and wheel slip for every corner of the car. Spot the front tire that locks up into the hairpin, or the rear that spins on the way out.
- Wheel slip shows lock-ups under braking and wheelspin on exit
- Temperatures and pressures build up over the stint
- All four tires, colour-coded, on the same graph
05Lap times
See how the stint unfolded
The warm-up, the peak and the fade, all on one chart. It is the quickest way to pick which laps are worth a closer look.
- Every timed lap on one chart
- Click a point to open that lap's telemetry
- Shift-click to compare it with the lap you are on
