An electronic control system for an internal combustion engine comprises first and second central processing units connected, respectively, with a fuel supply device and an ignition device for the engine. First and second sensors are connected, respectively, to the first and second central processing units for supplying their detected values to respective central processing units. Transfer lines are connected between the two central processing units for transferring detected values from the sensors from one of the central processing units to which the sensors are connected, to the other, and vice versa. The second sensor detects predetermined engine crank angle positions and supplies the resulting timing signal to the second central processing unit, which is responsive to the timing signal for supplying a trigger signal to the first central processing unit to cause same to start calculation of fuel supply quantity.
