Well my mpps cable showed up and I was able to successfully read the ecu. I would like to code out the rear o2 sensors and maybe if I'm lucky give it some of the power the s4 has ( wishful thinking)

I've read there is no real definition file for these? Where can I look to start with rear o2 delete?

You are going to have to hope and pray someone is feeling charitable I'm afraid. Those files are very different then what 90 percent of us work with. Post it, I will help if I can.

here is what i pulled from the allroad with the knock off mpps cable.
i was able to read the file using windows generic editor. my winols is currently messed up somehow.  everywhere where text is supposed to be in the file is just black. cant select maps. cant view code or anything.
not looking for a freebie. looking to learn locations and what not so i can do it myself. hopefully we can come up with something for the general public to use here. though im sure not many allroads with a 4.2 here.

Any chance the b6 s4 lines up somewhat similar?

Yes, the 560A (04 S4 manual) is very, very close.

What are you trying to do? Run catless, or completely remove the rear o2 sensors?

Both for now. 
Is it possible to use the s4 tune to get a bit more power out of it?  I know the bas doesn't have the forged internals like the s4 does. Not sure what else is different though.

Honestly, tuning the 4.2 is a waste of time unless it has turbos Smiley

Not like I'm asking for 500 horsepower.  It's just a daily anyways.

Your file is an interesting one. I'm working on it anyway for a manual conversion setup. I don't have enough to REMOVE the rear o2's, but cat shouldn't be an issue.

That it is very similar to the S4 file in every respect (addresses, calibration, etc).

Interesting.   I thought they were only similar?

Do I need to open up the ecu or get you numbers off it?

So if they are identical. . Then would this work as a definition file?


Think I attached the right file..

You can use that for CDKAT, yes. The rest, not so much. It's very similar, but not necessarily in the same places.
