Anti-lag Ignition Advance/Retard

This table allows for ignition timing to be altered when the Anti-Lag function is active. Typically a large amount of ignition retard is used. This causes the airflow to be maintained but little or no engine torque to be developed. This is turn prevents the engine speed from climbing, but it does allow sufficient exhaust pressure to be produced to maintain a high turbine speed.
