What Fuel trim do you guys usualy run on your logger? I read some where to try and get them as close to 100% as I could.
Right now my fuel trims are L=139.5 M=127.9 H=134.2 On saturday when I went to Nates, My knock was off the wall 42 was the highest and I think we got it down to 21. Did we do something wrong, or is this right. Not that I don't trust Nates tuning, I just want a second opinion on this. Because I still have knock and my fuel trims are all showing I'm running lean. Unless I'm reading it wrong. -------------------- Thanks, Bud!

Now, I've got a MAS Translator that I can put on, would something like that help or would I be adding too much air?
I'd probably get a new knock sensor as well to aid in the logging portion too. BTW, I did a WOT run tonight and found that the car was bucking in the 5000rpm + range. I don't know how else to describe it other than it was like stabbing on the brakes for a split second. What should I be logging to verify fuel cut? It looked like it was happening in fourth gear only (didn't get to fifth) and when knock was the highest. I'm hoping something in the drivetrain isn't binding up while it's got heavy load on it and at high speed. -------------------- "I hear he tunes the space shuttle also...and that thing is fast"
