As engine control apparatus for electrically controlling a fuel and ignition timing for a multicylinder 4-cycle engine comprises a plurality of first micro-computer each being provided for every one of or for every pair of cylinders in which compression and exhaust strokes are in phase, and a second micro-computer which is arranged to communicate with each first micro-computer. The first micro-computer calculates a fundamental quantity of fuel injection from a rotational signal and a load signal of the engine, a correction quantity according to correction control information from the second micro-computer, and controls the operation of a fuel injection valve, the ignition timing from the rotational signal and load signal, a correction quantity according to correction control information from the second micro-computer, and controls the on/off operation of ignition coils according to the ignition timing. The second micro-computer calculates a quantity of correction of said fuel and a quantity of correction of the ignition timing from at least one of parameters including an engine speed, an engine load condition, an engine temperature, atmospheric pressure, and an output of an oxygen sensor.
