Title: 4Z7907551AA xdf for 2004 Audi A6 BEL Post by: 2.7CEL on July 08, 2021, 07:24:42 AM Hello,
A bit of digging has turned up no definitions for the 4Z7907551AA box, does anybody have a definition file or can tell me if another, better defined, version is safe to flash to this ecu? I apologize for my incompetence as I have only started down this rabbit hole and due to a lack of programming experience, I would just like to learn from someone who knows what they are doing. If disassembly is my only path from here then I guess I better learn such processes and some German. I am just looking for basic emissions tunability (rear o2, sai, cat delete) for now and will need to do a lot more reading before comfortably developing a tune. Thanks in advance Title: Re: 4Z7907551AA xdf for 2004 Audi A6 BEL Post by: Blazius on July 08, 2021, 12:15:12 PM https://s4wiki.com/wiki/Generations
