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. Based on these
sensor signals and the ignition timing data, signals to interrupt the
primary current are sent to the ECM. The ignition coil is activated, and
timing is controlled.
