If you still have computer control 4 sounds about right. I have run it as high as 10 as long as the engine will start with out a bog. Good luck

Suggested Repair

If the engine still has computer control, about 4 degrees of ignition advance is reasonable in hot weather. Advance can be as high as about 10 degrees if the engine starts without bogging.
