Carburettor Setting
This chart displays wheel speed, rolling lap time, CHT
and EGT.
The chart is best viewed at run zoom, as it is then
possible to discern what effect the engine
temperature has on lap times.
•
Looking at the example, you can see the drop
off in laptime at 4000m as the motor is
overheated.
On 2-stroke motors, the combination of EGT and CHT
shows how well the carburation is working.
Normally EGT should increase when the throttle is
open (i.e. on the straight). If EGT drops while CHT
increases it indicates the onset of preignition,
caused by the mixture being too weak. EGT holding
level is what to aim for, but EGT increasing is safer.
Corner Radius
This chart displays wheel speed, cornering radius,
and timeline. A high radius value corresponds to
driving in a straight line and a low value indicates
cornering. The lower the value, the tighter the
corner.
Used in compare mode, radius is useful for seeing
variations in driving style, particularly on corner
entry.
Do a compare of Run 1 Lap 7 and Run 1 Lap 11
demotrak, demosess to see the detail in the
example.

The highlighted region shows how a wider
entry and tighter exit from turn 3 gained 0.1
seconds.
