I think anyone that's swapped over a D Can JBE onto a K line car may have some issues down the road.

I have a JBBF3 M swap on my MSD80, and what I've found is that my digital steering wheel no longer reads engine data and even the state's emissions computer couldn't connect to my dme to pull the readiness monitors...

Somehow, BMW specific diagnostic tools (ISTA, INPA, MHD) can still easily talk to the dme, but everything else is outta luck

I am now looking for a JBBF3 KL or finally retrofit my MSD81 I've been sitting on
