I only running about 20* of timing at WOT. Timing is something I really need to work on. I messed with it a while back and got it the best I could at the time without KR problems, but I think my fueling is much better now and I haven't taken the time to work on it again.

I'm currently shifting at ~6200 from 1>2 and 5900 from 2>3

 

The timing issue is a big problem. The traction shouldn't have been an issue, you aren't showing the mph with your time to suggest a traction problem.

 

Ya I didn't really think traction was a problem. Guess I need to get out and see what I can do with the timing. I know when I messed with it several months ago I had trouble getting any additional timing without running into KR problems, especially at the top of 2nd gear.

 

Well I made some quick adjustments after work tonight. It feels much stronger on the low end now. Probably still needs some work but I went from running ~20* timing at WOT to ~30* with no KR at WOT. Few spike of KR at other places for reasons I don't know.

I'm attaching log and tune if anyone cares to look. Don't pay too much attention to the AFR in any place other than WOT. I have it set up to run in kind of a lean cruise mode. There is a decent run from ~20 to 90 at around frame 5400.

 

I would zero out the afr spark correction.

 

Will do... Thanks
