ABSTRACT:
An engine control system in which a plurality of engine control data values corresponding to respective values of a predetermined engine operating parameter are previously stored in a read only memory, correction data indicative of a correction value for correcting errors of the engine control data values stored in the read only memory is stored in a rewritable memory, and one of the engine control data values corresponding to a detected value of the predetermined engine operating parameter is read out from the read only memory, while the correction data stored in the rewritable memory is read out to obtain the correction value, whereby the read engine control data value is corrected by using the correction value in order to control the engine based on the corrected engine control data value.
