Electronic Control Module (ECM)

The ECM is located behind right side of instrument panel and is the "brain" of EFI and Computer Command Control systems. Information from all data sensors is received and processed by the ECM to produce proper pulse duration for each injector, correct idle speed and proper spark timing. The ECM uses an operating reference voltage of 5-volts to all data sensors.

The ECM performs calculations to control the following EFI operating conditions: engine start, engine flooding, engine running, fuel enrichment during acceleration, lean fuel mixture during deceleration, fuel cutoff and battery voltage correction.
