Ignition timing is controlled by the electronic control ignition timing system. The standard reference ignition timing data for the engine operating conditions are preprogrammed in the memory of the ECM (Engine Control Module).The engine operating conditions (speed, load, warm-up condition, etc.) are detected by the various sensors.
