I am looking for a definition file for a 4z7907551k ecu out of a 2001 2.7t tip allroad.

Sorry, I posted the last post from my phone and didn't want to type to much.

I have been interested in tuning for a while, and this website seems to be a great source to learn how to do it. I currently drive a 2001 Allroad, unfortunately the rear o2 sensors have been acting up and I thought that would be a good place to start learning how to reprogram the ECU.

I am still working on trying to get the software to read my ECU, it keeps failing to read. But in the mean time I have downloaded a stock 4z7907551k and been using tunerPro to look at it. I have been using the 4z7907551G definition to look at it since it seems to be similar. But I would like a 4z7907551k definition file. Also I would like to know a source I can look at to figure out how the definition files are created.

I have tried to search for the definition file, but there doesn't seem to be much information for this particular file.

Thank you in advance for for help.
