So who wants their ECU's "Chromed"?

Thats what I am using, and thats what I've gotten the reading of 0.1 on all 3 fuel trims. I'm gonna change the injector size and see what happens.

I just looked at a couple of my logs and all 3 of my fuel trims are lock at .1 as well. The only thing that moves is the o2 Feedback. I have not had any time to start playing with the scaling and latency as I just finished the brakes up and rerunning some vacuum lines. I am at the point I would like to start getting the tune dialed in and would be interested to see what you come up with.

you MUST fix the o2 sensor wire or it will never work.

[Goallie11]

Ok I will do that, I'm pretty sure I have a spare in the garage that I can swap in.

I also just changed my scaling to 500 and that didn't change anything, it ran even leaner actually at idle.

Still trying to upload a log and I'm getting pretty pissed now that something so simple won't work, it's giving me invalid file whenever I try to upload anything.

nothing will work right until that wire is fixed, there is no point in trying anything else. The only other thing you can do is disable o2 feedback, but I would just fix the wire.

I'm a little confused, if the rear sensor is the only one used for feedback when bit02 is disabled, how does his front wire being cut affect anything? What am I missing?

It is confusing to me too, so I'm in for an explanation.

When I went to replace it, I remembered why I haven't before. The connector was fused to the connector from the car when it touched my intercooler hard pipe, making this a whole lot more painful then it should be.

[Chris@Rvengeperformance]

The front and rear are switched in evoscan.

Believe me if your o2 trim is +12 and the o2 reads near zero volts that is your problem.

Ahh, I see. Yeah, that definitely would be the problem. Thanks for clarifying.

Yes the front O2 in evoscan is really the rear... That is fixed in the new version xml.

Actually, EVERYTHING labeled front is the rear... Fuel trims, afr, idc, latency, etc, etc.

The evoscan guys aimed that the primary was the front and in reality three primary is the rear...
