Engine Control Module: Description and Operation

    The Electronic control unit (ECU) evaluates the data delivered by the various sensors concerning the engine operating conditions, and from this data
generates a control signal for the electro hydraulic actuator, and the idle control valve.  The ECU also controls warm up enrichment based on signals
from the coolant temp sensor.
