Gear Shift Ignition Retard🔗

This is the amount of ignition retard requested by the Shift Ignition Retard module:

  • In normal mode, this is equal to Normal Mode Gear Shift Ignition Retard.
  • In performance mode, this is equal to Performance Mode Gear Shift Ignition Retard.

This is sent to the Ignition Target Demand module, where it is combined with other cuts and retards and applied to the base ignition angle in order to determine the final ignition angle demand sent to the spark plugs.
