Abstract
The present invention is an ignition control system for an engine having an ignition system. The ignition control system is arranged to determine if a speed of the engine is decreasing at greater than a predetermined rate, and if so, to initiate an ignition timing compensation mode in which target engine speeds during the time of deceleration are set. These target engine speeds are compared to the actual engine speed and a firing timing of the ignition is advanced if the actual engine speed is less than the target speed and the firing timing of the ignition system is delayed if the actual engine speed exceeds the target speed.
