Description

Ignition timing is controlled by the electronic spark advance control system. Standard reference ignition timing data for engine operating conditions is preprogrammed in the ECM (Engine Control Module) memory. Engine operating conditions (speed, load, warm-up state, etc.) are detected by various sensors. Based on these sensor signals and ignition timing data, primary current interrupt signals are sent to the ECM. The ignition coil is activated and timing is controlled.
