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!

QUOTE (turbohcar @ Nov 1 2005, 08:38 PM) I'll have to do a log of airflow but there are spots in this log where it shows 0.0ms of injector pulse during the WOT run. Mind you, this car still retains the stock fuel system and the fuel pump has not been rewired yet. Have you ever had the fuel rail off? Check the injector sheets and rings. Bad seals at the rail will cause a high end miss. Fuel cut is loud, or at least it was in every DSM I've ever driven. Usually makes an interesting cloud behind you for a second. Feels more like hitting a wall than tapping the brakes. Not really, but my point is that it is not gentle. -------------------- 2009 Scion Tc
