[QUOTE="CJK440, post: 15298770, member: 43980"] Quoting myself here. One other thing I noticed. The RPM flare is accompanied by 25 or degrees of timing for a fraction of a second. I also noticed that high timing is during spark source 1, base timing. So on a crank datalog my spark source starts at 0 (crank) then when it fires goes to 1 (base) for a 1/10th of a second then goes to 9 (idle feedback) for a tiny bit then goes to 7 (cold engine low load). Should spark source be going to base right after crank??? [/QUOTE]
