Abstract
To determine an optimum advance angle for activation of a spark plug in relation to an amount of air sucked into an engine, an electronic ignition control method and apparatus comprises a calculation circuit to calculate a linear equation representing a relationship between the optimum advance angle of activation of the spark plug and the amount of the sucked air in consideration with rotation speed of an output shaft of the engine, thereby to simplify the calculation.
