ABSTRACT:
An electronic control device for internal-combustion engines in which, when the engine has begun a slow-speed hunting state, the ignition timing is changed from the first ignition timing to the second ignition timing; and when the slow-speed hunting state is released, the ignition timing is changed from the second ignition timing to the first ignition timing; and this ignition timing, when changed, gradually varies.
