Electronic control system
The ECM controls the ignition timing, the fuel injection timing, the fuel injection volume, and the ISC
and it maintains a stoichiometric air-fuel ratio in all operating conditions, including starting and idling.
Also, the ECM converts the signals from the input sensors and sends instructions to each part.
