I wish it was as easy as being lean. I've had my O2s up to 940+ and it only seemed to get worse.
I'm gonna hold off and see what my try with a completely stock file does tomorrow. Though, more advice is appreciate because once I determine that something in the tune is wrong, I have to be able to fix it.
Here's my car in detail...
2004 L36 (Series II/III hybrid)
67k miles
3.05 gearing
Stock TB
Stock MAF
WizAired
Factory plugs/wires (will soon become AL605s and PRJ wires)
Stock manifolds
Stock injectors
ZZP 2.5" DP
No rear O2 sensor (codes deleted)
Mandrel 2.5" custom catback
I guess that's as much info as I can provide. The car doesn't act weird like it's a mechanical issue. Just as soon as PE kicks in it knocks crazy. That leads me to believe its dumping too much fuel because if I was running lean then I'd be knocking before PE, too. Make sense?
