ABSTRACT:
In a control system for an ignition timing of an internal combustion engine and a control method for the ignition timing, a basic ignition timing of the engine is set, an engine speed is detected, a target value of the engine speed is set while the engine is in idling condition, an ignition timing correction amount is determined depending upon a difference of the target value and a detected engine speed while the engine is in idling condition, the basic ignition timing is corrected with the correction amount, and after the engine speed becomes higher than or equal to a predetermined value, the engine is controlled with the corrected ignition timing.
