You can't write through the encryption board. Honestly though, just solder in a new 800BB, and quit wasting your time.

this x1000

Depends on the file. Some files are only for a certain trans. Some have multiple maps to support both, and the ECU can be told which one to use via coding (using VCDS).

4B0, 4Z7, or 8D0?

Has literally nothing to do with the XDF btw.

Why are you using the 8D0..551M xdf  with a 4B0 file?

You need to do some more reading. It's hard to guide someone when they don't have the basics covered.

Will that have any conflict with the IMMO 4B090511AL.

This is my understanding of it.

The XDF reads the layout for the maps/tune bin file. The 8D0551M XDF is for a manual S4. Im putting a 4B090511AL tip A6 file in it.

Now this is where im kinda stuck. So the XDF file already has a pre-layout for the tune of an APB manual. Why that tune will start my APB A6. And their is no communication to the tip as their are no files for the tip. The XDF cant read the tip files as its not laid out for it.

I can either make a custom XDF for the 511AL, I dont want to do this at this point in time. Or find a 511AL XDF file. Or any APB tip XDF and defeat the IMMO?

Someone did say they made the files to convert to tip and put it in the definitions section. He did this for the community tune as it is for a manual.

I looked high and low, couldn't find it.

I also looked everywhere for my stock XDF and got nothing. Im thinking I can use any APB tip XDF and should work if I use the 511AL tune to it.

If my understanding of it is wrong, please clarify. I read and then read again, then followed the steps in s4wiki. Having another description worded differently might help the noobs get a better understanding of it.

Thanks
