Thats the way has ecu came to me. I only change 2 bytes. I do not have from this kind of ecu any other ori file, so i guess its ori file.

...so i guess its ori file.
It is not. Compare it with my file and see the changes. Mine is original. Data at the final end is individual diagnostic session data and therefore differrent on many cars. Ignore that.
With my file as ori basis you also see the checksum changes from your (tuning-) file.
