E46 (1999 - 2006)
Okay, So as the title says I want to put an SMG transmission on my 325ci.
I know that it will physically fit (the M54 and S54 have the same bolt pattern).
Now how hard will it be to program the DME? Can i get a DME from an M3 and use that?
Now Please i don't want any hate over my choice to want...
