<P>PROBLEM TO BE SOLVED: To provide an engine control device improving accuracy of ignition timing in undetermined engine speed when an engine is started in an early stage. Ž<P>SOLUTION: In this engine control device, engine ignition timing determined based on a reference rotational position and an Ne signal corresponding to a missing tooth part from a crankshaft sensor is corrected with respect to a delay in a response according to the engine speed. When early start-up is performed by an economical running system (ST1), it is determined that it is before first ignition (ST2), and the engine speed is not determined (ST3), a preset value based on a correction value with respect to the delay in the response according to cranking speed when the engine is restarted, with an environmental temperature condition satisfied, is read from an ECU (ST4), and the correction value with respect to the delay in the response according to the engine speed when determining the first ignition timing in restarting the engine is set to the preset value (ST5).
