Re: Spark advance tuning made simple and quick?



Gentlemen, I have an idea that may save tons of time when tuning spark 
advance. In general, I have a very simple way of manually adjusting spark 
advance a known amount on the fly while driving. That way, you could set the 
entire SA table to say 25 below 60 KPa and say 5 above 60. Then, you could 
drive at known RPMs and MAPs and just manually dial up the SA while listening 
or watching for knock counts on a scantool. Once you hear or witness knock, 
just write down where on the RPM vs. MAP map it occurred and how much advance 
you had cranked in and how much you backed out. Then, its just a matter of 
reburning the chip one time with the results of the run. If there is any 
interest in this procedure, I'll write it up in a website with digital photos.
