Ignition Knock Retard Proportional Gain🔗

Each cylinder cycle that knock persists and the Knock Retard Limit has not been reached, an additional amount of ignition retard is applied to reduce knock. This is calculated by doing the following:

  1. The value specified here (in degrees per volt) is multiplied by the amount that the knock sensor voltage exceeds the knock detection threshold.
  2. The resulting amount of ignition retard (in degrees) is added to Ignition Retard Feed Forward.

A higher gain value means the system will react more aggressively by applying a greater amount of ignition retard.
