OMEM710 Hardware Manual 2v11

The full throttle gearshift is a switched ignition retard function. When the input for this function is
satisfied (normally by a physical input switch on the clutch pedal or gearstick), the ECU retards the
ignition at a rate, FTG Retard Rate, up to a maximum retard, FTG Retard Max (The maximum
retard is relative to the current map value, not absolute with a maximum absolute position of
30ATDC). When the input switch changes to OFF, the ignition retard will be returned at a rate, FTG
Restore Rate, until the normal ignition timing is reached. If the input does not go to OFF, the timing
will be returned after a time set by FTG Time max. The retard rate and restore rate are degrees per
4ms. The option FTG min RPM is the minimum engine RPM at which a full throttle gearshift retard
can be performed. This prevents the engine RPM from dipping when depressing the clutch whilst
stationary.
