ABSTRACT:
An Electronic Engine Controller (EEC) controls the fuel delivery to an intake of an engine which is equipped with an intake system which includes primary and secondary runners, a primary throttle plate for controlling air flow through both runners and a secondary throttle plate for controlling air flow through the secondary runner. The EEC determines values indicative of the actual and equilibrium amounts of fuel existing in the intake system and controls the fuel delivery based on such values. The actual and equilibrium amounts of fuel include a value indicative of the change in equilibrium fuel due to change in the secondary throttle position.
