So trying to flash my 14 6.7 with my V2. Have it unlocked with BD. The tune I got matches the number off of the controller. Verified via the v2 software and physically checking the controller.

When I go to flash it wont allow me to do so, says error code 531 and controller mismatch.

Any ideas on this. Thanks.

Well updated the patches. I also got a stock file tune from my tuner. Was able to activate the vin and install the stock file tune which is good. However when I went to install the modified tune it came back with the 531 code again. Guess it must be the modified tune then. Asked him to maybe try rebuilding the modified tune but I dont know much about these things.

Only thing I saw that was glaringly different is the OS number which is different from the stock file tune and the modified file tune. Not sure if that number matters or not.

The OS numbers are different because of being upgraded to a CSP4 tune.
