Re: ecm conversion, 1986 to 1989
ok, that's odd. spark retard is proportional to rpm?
You know where I normally see that? On (turbo)supercharged engines, spark timing is retarded as boost (and therefore rpm) increases. Yes, your ecm is acting as if it hit it's head and woke up thinking it was in a grand national or t-type.
Your Thoughts?
