Greg,

I think you're still running lean. WOT O2s look are at 920ish. I think that they need to be closer to 940. Give her some more fuel.

The RPMs never seem to get very high, are these WOT runs?

I'm also trying to figure out why you would get any KR considering your engine temp doesn't get above 90*. Is that C or F?

What car is this? I'd put a bigger pulley on and see if it gets rid of all of it. It's like me trying to tune my car with the 2.6" pulley with pump gas on the street with 18deg. adv. No matter what....it wasnt gonna cooperate. I put a 2.8" on and now no KR and mo happy.

Greg

Your LTFTs and STFTs look great. From that scan you showed, they locked in at 0 during PE consistently.

I would go into the MAF table and bump up values past 7500hz. That's the point when the car goes into open loop (PE). You raise those values, you tell the PCM more air's coming in so more fuel is added. I think that's the best way to do it because your fuel trims are already great.

Shawn its the wife 98 gtp with a 3.5 and vs cam i just ordered a a fwi to see if getting cooler air in will help a bit. but if anyone has time to sit for a few runs and some help I would luv it... no big hurry either.

jeff I will look at the tables, I took a bit of fuel away from what i had lastnight and gonna let her drive it to set ft's again scan and see where its at. so far it seems ok compared to what it was. plus it was loading up bad at wot alot of excess fuel out the pipes..lol nice cloud so scalled them back to about 11.18 from 11.1

Yeah, see if you can get another scan up soon.

I hope the <1.5 hours you get out of the battery isn't getting on your nerves yet. I'm not sure how much help I'd be but you know I'm always in.
