Every time I plug the V2 into the OBD2 port it resets the Factory clock to 1:00. So Far I have Noticed It does not matter if it is conected to the computer or not Prior to pluging it into the OBD2 Port. It also does not matter if the Key Is in the ON OFF or in ACC mode. I have the latest EFILive software and firmware installed.
Truck Is a Stock 2000 Silverado 1500 ECSB 5.3L Auto. No aftermarket electronics.
