OM648 swap into a w123
I use a PCS tcu for the transmission. It is also handling the CAN communications for the ecu to operate outside its original evironment. I can run it in factory cars as well but I do not have the early CAN structure. I can run the transmission just fine from the CAN but I do not have start auth in place. So you have to piggy back the factory tcu for that. ON later cars, ie 2002 and up with ME2.8 etc. It is pretty much plug and play.
