Ignition Target Demand🔗

The Ignition Target Demand module calculates the final ignition angles applied to the spark plugs.

To perform this calculation, the following angles are added together:

  • The Ignition Angle Requested by the Ignition Angle Module. However, if knock is detected, the ignition angle may be modified by an amount of ignition knock retard for the cylinder(s) in which the knock is occurring.

  • When using nitrous fuel, a Nitrous Ignition Retard may be applied.

  • Ignition Angle Correction requests for the individual cylinders The following angles are then subtracted from the total:

  • The Traction Control Ignition Cut Requested

  • An ignition retard value that is derived based on soft limiters, hard limiters, and Shift Ignition Retard The module also calculates the final Dwell Time Demanded based on the Dwell Time Requested generated by the Dwell Time module.
