"All Sane" people here do not work with an Xede. You should not
install it prior to the turbo. Period. If it were a standalone ECU, then yes you should. But not the Xede.
I would recommend that you call me for assistance. This has been going on for over a month now, but unless I get more info and you call me, it is not going to get any better.
We need to go thru the harness. I believe the problem lies there, or that your MAF wires are loose.
What year is your car?
What year was the car that the harness came off of?
Are the wires in the MAF connected well? Are they loose?
What is the injector scaling set at? Click on features > Output scaling. What is listed for AN0?
From the maps posted, your O2 map needs to be all 0's below the -10's. No if, ands, or buts.
Your timing advance is ok. That will actually make it run leaner and better at idle. It is also the reason for the random cylinder misfire code.
Without this info, I am at a loss as how to help. If you give me a call, we could get it worked out alot faster! There is a simple fix here somewhere
