Say someone wanted to take a modified ECM from say, a 1999 300M, and install it into a 2001 LHS. If you got the VIN's changed in the ECM, what would not allow the 99 ECM to control the 01 motor? Even if they aren't the same code motor (they are both 3.5 HO's)
My theory is that it will work....if you change the VIN, and it matched the BCM, that should allow it to work. I think it is like the TCM's (from 99-01) they are interchangable...
