Abstract
A common type engine controller controlling an automotive engine in accordance with the kind of the associated transmission (i.e., automatic or manual) includes an electronic control unit 54 consisting of a microcomputer. When used with an automatic transmission, the power supply circuit includes a neutral switch 53 inserted between the starter switch 51 of the vehicle and the magnet coil 52 controlling the current supply to the starter motor, wherein the starter signal S.sub.T is supplied to the electronic control unit 54 from the junction between the neutral switch 53 and the magnet coil 52, the neutral signal N.sub.T being supplied from the junction between the starter switch 51 and the magnet coil 52 (FIG. 2 ). When used with a manual transmission, on the other hand, the starter signal S.sub.T is supplied from the junction between the starter switch 51 and the magnet coil 52, and the neutral signal N.sub.T is grounded. Upon detecting the high level of the starter signal S.sub.T, the electronic control unit 54 determines the kind of the associated transmission based on the level of the neutral signal N.sub.T.
