Abstract
A system has a table storing initial timings, a rough correcting section for correcting an initial ignition timing derived from the table with a rough correcting quantity, thereby producing a basic ignition timing, and a fine correcting section for correcting the basic ignition timing with a fine correcting quantity to produce a real ignition timing when the rough correcting quantity becomes a predetermined value. The rough correcting operation is stopped when a predetermined time elapsed during the rough correcting operation, and the fine correcting operation is started.
