Engine Control Module - Description and Operation - General
sophisticated feedback system to constantly readjust the various basic control settings. These values are then stored in its electronic memory.
The adaptive capability allows the ECM to compensate for changes in the engine's operating conditions, such as altitude changes, intake leaks or other
deviations.
If the vehicle battery or MPI ECM is disconnected, the vehicle must be driven for a few minutes so the MPI unit can "re-learn" its operating
conditions.
