Has anyone tried swapping out a BMU--is this possible or is the VIN encoded into the BMU, CMU or pack somehow that would prevent operation if this were done?

Would it require a dealer visit to reset the system if it were attempted?

i have a spare BMU to play with and just wondered what might happen. i have dismantled the BMU and want to document the circuitry and extract the firmware if possible, and explore the CMU CAN buss that is not accessible from the OBDII diagnostic connector.
 
Dani has run parallel packs in this thread, with the car reading either pack without throwing a fit. So, I'd say the BMU/BMS is not VIN encoded.
