ABSTRACT:
A method and a system for engine control are disclosed. Electrical signals representing the engine operating conditions are detected, which electrical signals, together with the control data stored in a memory, are used to calculate a correction factor for correcting the control data for controlling the engine, where the correction factor is stored in a volatile memory, thus controlling the engine on the basis of the control data corrected by the correction factor. The correction factor stored in RAM is transferred to a non-volatile memory under predetermined conditions. Even if the voltage applied to RAM is reduced to a level lower than the storage ability of RAM, resulting in the loss of the stored data, the correction factor stored in EAROM is transferred back to RAM upon restoration of a normal voltage at RAM.
