Hi everyone, seems like there is not a definition file (xdf) already in the forum and noone has it, so I'm trying to make it.
I tried every audi tt 8n 225 and 180 definitioon files here and they do not match.
So i picked up a well defined file and its ecu.bin and started bulk edit the offset to one easy value i found (NMAX must be 6800), calculated the offset but only NMAX was right the others are all over the place unfortunately.
Moreover, other values are hard to find since it's my first time seeing ECU data and I don't really understand it...
Is anyone here more expert and available to help me or just pointing me in the right direction?

The next step is understanding how to tune, but i found the forum here and also s4wiki a bit confusing on certain points, is someone available to maybe screenshare or something to get me started?

Attached everything I'm using.
