IGNITION TIMING COMPENSATION FOR EN-
GINE KNOCKING (FOR VEHICLE WITH IGNI-
TION TIMING ADJUSTING RESISTER
CONNECTOR)
The ignition system basically needs no adjustment for ignition tim-
ing. However, due to fuel quality or other reason (mainly counter-
measure against knocking), the adjustment may be needed. If so,
adjust the ignition timing as follows.
1) Replace the register with the smallest degree-change register
(–15 or 15) as your purpose. Check if the result if satisfactory. If
not, replace the register with next larger degree-change register
step by step until satisfactory result is obtained.
