Files attached, there's some nasty KR and I'm not sure what the best way is to fix it.
The tuning runs awesome and pulls really hard otherwise.
ChrisJ, this is mostly your old tune... just trying to tweak it to work on mineIt's my daily driver so I'm trying to get this dialed in asap.
Thanks for any help.

I had to get the fueling right to get rid of that KR. Do you have a wideband? Set your PE to 12.8 straight across and get that dead on and see if it doesnt go away, then set the Pe to where you want it. I will send you another timing table to try, its a bit different, but I think it will work well for you, it uses the AFR adder instead of having it zeroed out like the one I sent you. I have just had better luck using it on trucks.

Hey thanks man!
No wideband here
I'll try it and post the results. If I could just get rid of the KR I'd be happy, everything else seems to ROCK.

I will post the last tune I did in the morning. Get the main spark tables, AFR adder table, and the PE tables over. Also check the min spark advance table. Those are just a few things I changed to get more timing and no KR.

Man I was just looking at your log, do me a favor, run this tune straight up as it is, then send me a log and I will adjust it a little. Take the log after running it for a day or few. I have seen it take a bit more timing after being run for a day or so. I think the PE and timing is a bit different between these two tunes. I just want to see the differences in fueling and KR between our trucks, this tune was perfect on mine.

Will do man, and thank you for your help... I'll upload it this weekend and post a log file next week some time.
I know our trucks are/were pretty similar (Z06 cam, etc). No tranny mods for me yet but I'm sure it's coming up quick lol.
Thanks Chris!
