July 1: So it begins. Don't worry, this is not in the correct legal jurisdiction!

Detonation Retard Operation

During detonation, the ECU retards ignition timing (maximum 12 degrees at crankshaft). If the detonation sensor circuit is shorted or open, the ECU retards the timing by a fixed angle (8 degrees at crankshaft).
