How mechanically/electrically (is that a word) inclined are you? It's in the service manual, so I'll let that explain it. It has the specs in there too.

You can also check your ROM by opening it up with EcuFlash. Get there and I can get you the rest of the way.

here are two logs in evoscan that i did this morning of STFT (O2 Feedback), AirFlow, Injector Pulse Width, Injector Duty %. Any help or input would be great.. still trying to get down to the bottom of this rich idle. The longer log is of me driving in 4th cruising and then pulling over and idling. The shorter log is just me idling for a couple minutes. Logs are in a zip on rapidshare. http://rapidshare.com/files/3989561819/logs.zip

I bought another maf and installed it last night and let it idle. It hovered around 14.7 when I first started it and then as it started getting warmed up it stayed at 14.4 like it did before.. I will do an idle log later tonight when I get a chance. Now I really have no idea what the hell could be causing this...

It may be your WB sensor. BTW, I tried enabling different bits and couldn't get it to idle rich. I'll keep working at it.

idk how it could be thought this wideband sensor is only a few months old and I just replace my front o2. I even replaced my maf and nothing has made a difference. I talked to prosport about my wideband maybe being wrong and they said that if it were bad then it would be off my a lot not off by .3-.6 you think I should have them replace it for me anyway?

Does your MAF Scaling not include the MAF Adder?
