Hi everyone I'm a noob so please be patient with me, I have a Audi tt 225 bam which has a bad map which I want to remove, the map was done by the old owner and is too aggressive for my liking,

I do not have the origional .bin file but I have downloaded from here a stock file that matches my ecu model number. Question is if I flash the ecu with the new file will this mess up my immobilizer? Or is the immo stored on a serparate chip? I just want my car back to stock.

Much appreciated

Chris

Appreciation stompen, many thanks chris

If you have the original .Bin for your car, all you need is the cable and nefmoto.
Everything else is found in the nefmoto folder.
