not to be the bearer of bad news, but i believe thats a 512kb ecu, and not compatible with all of the b5 s4 m-box 1024kb bin files found on this site...

Yes it is a 512 file, but if I change the ecu the car works?

you need to cut out immo from new ecu if it has and rewire camshaft adjustment units in your motor harness(cut wire from right to left shifter and put it from right to ECU), because 1024kb ECU have a separate  control of phase shifters

even if you just plug a new one box without immo to a motor wiring - it will run. I did it and it worked.
