The mileage on the cluster end is stored in flash memory within this microcontroller. If the cold boot via battery disconnect doesn't work, It may be possible to move the core over from the old to new cluster. The question is if the microcontroller is programmed generically and it drives whatever is available on the carrier it is plugged into, or if it is programmed specifically for the carrier.

Has anyone tried this yet? I just read through it all and didn't see anyone saying this didn't work.
