If an alarm is displayed during running, it is the teams responsibility
to bring the car into the pits. If an alarm is ignored the team will be
responsible for any damage which may be caused to the engine.
7.3 Engine speed limiter
Engine speed is limited by the ECU at 6750RPM. It is tolerates to use the limiter during maximum 3
seconds continuously.
We have 2 separate limiters:
Absolute IGNITION LIMITER: 6750 RPM (above
this value the ECU doesn’t fire any cylinder)
To get smother limitation there are 2 pre
‐
limiter band (one for IGNITION and one for INJECTION). The
pre
‐
limiter band is setup at 50 RPM from 1st to 6th gear under absolute limiter.
This means that the
engine starts limiter is 6700 RPM.
For Neutral and reverse, Rev limiter is 4000 RPM
