Ignition timing is controlled by the electronic control ignition timing system.
The standard reference ignition timing data for the engine
operating conditions are pre-pro grammed 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. Based on these
sensor signals and the ignition timing data, signals to interrupt the
primary current are sent to the ECM.
