Well the engine swap went great as far as the engine but have problems with the transmission going into limp mode upon more spirited acceleration. I get a code 100 Speed monitoring fault;

Speed ratio n-ab:n-mot
not correct for speed
currently selected

The transmission had a fresh rebuild when I bought it although it had been sitting for about a year. Not sure if I have a transmission problem or a transmission control unit problem. It does seem reasonable that the control unit might have a problem going from the former 525i engine to the M3 engine. I believe the TCU gets some sort of information from the ECU. Anyone have any ideas?
