Re: My recent Dyno/AF Chart from Kelley Performance ('97 C5)
Well done...that's to be proud of. What's your procedure?
We all know that the stock o2's are no good for tuning and they are terribly inaccurate.
We Know "Lean is Mean" and we know K/R is bad and shows up when you are too lean. So this is the premise behind the tune.. To get as lean as we can without introducing k/r
1. Pick a close PE value in the PE vs. RPM table to start with. I used the value in the 5500rpm which was 1.1996
2. Put 1.1996 is every PE cell across the entire rpm scale
3. Go take the car out and log a few WOT runs up to redline
4. Look for Knock Retard
5. If no K/R then reduce the Entire PE table by 1%
6. Run a new log and look for K/R if no K/R go to step 5.
7. If you get K/R then ADD 1% back to the PE Table
8. All Set
1. If you get K/R on the 1st Try then ADD 1% to the Table
2. Log and look for K/R
3. Repeat step 1 until K/R is gone

chuckster,
Man, your AF chart (and dyno chart) is flat awesome! I'm assuming you took the 'curve' out of the PE table and now run it 'flat' (all numbers the same) to get that kind of a AF curve?

I did it this way to easily monitor what was happening in all the RPMS.. If I got k/r in...say, 3500-4000 then I'd bump that block up 1%
But it turned out to be perfect the whole way..

Cool man, that's what I wanted to know. Could you tell a difference in how it ran after you flat-lined the PE table? Did it run better?
