Abstract
An ignition timing control system is provided with an ignition timing computing unit which determines a maximum acceleration ignition advance .alpha. ACMAX in accordance with an intake pressure difference P and a water temperature T of the engine. When an acceleration is detected by a rapid movement of an acceleration pedal, the maximum acceleration ignition advance is added to the normal ignition advance. Thereafter, the maximum acceleration ignition advance is gradually reduced to zero in accordance with the lapse of time or a change in the engine speed.
