WebThe value refers to degrees of ignition timing advance. The feedback knock correction will start with a small value (-1.41 degrees) and keep retarding timing until the ECU no longer detects a knock event. The ECU doesn't detect the severity of knock, just determines if knock is present. It retards timing in gradual steps until the knock stops.
