ABSTRACT:
An ignition timing control method and an apparatus for internal combustion engines in which the ignition timing of the engine is calculated from a base value obtained by detecting a first operation state of the engine and from a learned correction value obtained in accordance with the record content of a nonvolatile memory, the ignition timing being corrected by rewriting the nonvolatile memory in accordance with the detection result of second and third driving states of the engine, as desired.
