not sure what more there is to know? If my current zf8 died, and I plopped in a replacement unit. What more other than a protection issue might I face? If the tcu has a tune on it, what issues may arise? I bought a whole spare car, ecu was tuned, tcu still tuned.

I understand there are no immo defeats (yet but in progress) but needing to adapt via odis. I may never swap it. Call it a technical exercise.
