a calibration reflash is only permitted when both operating systems are compatable
then i tried doing the same reflash on another ecm and it said this
the tune files operating system boot block number 12605811
is not compatable with the ecm's boot block 12603417
a full reflash is only permitted when both boot blocks are compatable
i want to completly reflash the ecm with a completly different stock tune.
