I really don't know much more about latest ZB for our cars than is in that N54tech thread. I also do not know if there is a different flash for XI, I doubt it. My AWD works fine with Alpina, no errors or codes.

I remember one guy was getting errors related to DSC and it was thought he may have messed up going back to the wrong TCU file (for non XI vs XI) but that makes no sense. Cannot remember which forum that was on, maybe here?

Don't know about the various throttle adaptations either, but I would guess it is NOT the same as the gas pedal thing. These INPA adaptation resets are more for replacing and re-calibrating ECU/TCU to new hardware pieces. The gas pedal thing just resets a short term memory of driver behavior.

There are as I am sure you know ECU resets that may or may not include throttle mapping. Cobb for example lets you reset ECU parameters, but it is not clear to me how extensive that is WRT resets allowed in INPA.
