Engine Control Module: Description and Operation
General
Motronic Engine Management System V-8
The Motronic electronic control unit (ECM) processes input signals, filters out stray signals and sends the results to the operating components of the
fuel injection and ignition systems.
The ECM also provides for self-diagnosis of the Motronic system. The Motronic system is adaptive or self-learning. The ECM learns continuously by
using a 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
