Abstract
A desired value of ignition timing and a correction value therefor are calculated at a timing corresponding to a first specific one of sensed predetermined crank angle positions of each cylinder of the engine. Data indicative of the calculated desired value of ignition timing are set in a counter to start counting based upon the set data at a second specific one of the predetermined crank angle positions, subsequent to the first specific one, so that the ignition takes place upon completion of the counting. When it is determined from the calculated desired value of ignition timing whether the ignition is to be effected after a third specific one of the predetermined crank angle positions, subsequent to the second specific one, the data set in the counter is updated to the calculated correction value, at the third specific one of the predetermined crank angle positions.
