Ok here is what i found out:

Both the 128i US and 330i N52 EU model have the MSV80 ECU and also have the same base version MM10S.

The latest 128i ZUSB is: 8619524 (manual transmission and maybe ZF automatic transmission??) and 8619558 (GM automatic transmission).

The latest 330i ZUSB (E92) is: 8619534

As there is no RSA bypass for that base version, you can not change the byte and just flash it. You can flash the file with WinKFP, read it back with BB App 2.0 or a tuning tool like Kessv2, change the byte and flash it again.
