Abstract: An engine control device includes an obtaining unit, a determining unit, and a control unit. The obtaining unit obtains model information on an engine based on a signal from a sensor, the sensor detecting a rotation of a camshaft unit. The determining unit determines whether the model information obtained by the obtaining unit matches stored model information. The control unit gives a warning to a user when the determining unit determines that the model information is not matched and controls the engine corresponding to the stored model information when the determining unit determines the model information is matched.
