No you aren't. The M-box one you have is good for what you want.

I thought that the different MAF and other, smaller differences would prevent a match, since there are separate and distinct ECU Eeprom Images for the 8D0907551 M, D, C and K.
Just goes to show that I think too much.
I really do appreciate you answering my seemingly endless questions...slow learner here..!
