    I changed the vin to an 02 vin number then I did a full flash on the pcm. I went back and looked at the o.s. with my V2 and it still shows my vin number and the cts still wont work. This crap is irritating, why cant edge just update there side so it will work. About ready to unload it for a different setup.

    Open the V7.5 tuning tool and connect the V2 and cable to the truck, go up to the flash tab at the top and select PCM security, when it opens select the VIN/BCC tab and go through and change the VIN number. The VIN is stored in a separate spot in the ECM and has to be upgraded separately of the tune.

    It is a shame that EDGE won't address the issue.
