ABSTRACT:
In an electronic ignition control apparatus having RAM to initially store first and second signals indicative of the starting and terminating points for calculation of a time necessary for rotation of a predetermined angle defined by integer times as large as a predetermined angular interval of an output shaft of an engine, a rotation time of the output shaft is calculated during rotation of an angle of the output shaft defined by the first and second signals from RAM to calculate an optimum spark advance angle in relation to the operating condition of the engine such that an angular position defined by integer times as large as the predetermined angular interval at the advance angle side of the calculated advance angle is determined to be stored in RAM as a third signal. Calculation of a time defined by the difference between the calculated advance angle and the angular position defined by the third signal is started upon arrival of the output shaft to the angular position defined by the third signal from RAM and completed to deenergize the ignition coil of the engine previously energized.
