mr954 Posted September 17, 2018 Report Share Posted September 17, 2018 So, I just received my Steeda CAI with BDX tuner. I went to flash my car with the canned 93 octane tune, and low and behold, my tuner reads a different VIN on my he PCM. I was hoping that the tuner was in demo mode, but no. So, now my tuner is paired with a different VIN. If I change the VIN, my device will have to be unlocked as it is now paired with a different VIN. Pissed because the car has been service numerous times without this being mention. I guess the PCM was swapped by the previous owner. I drive an 07 very and the PCM is registered to an 07 coupe. Would the different VIN affect the uploading of tunes. I understand timers don’t use the BIN, just the serial number and 4 digit code on the PCM. Thoughts?

Macman756 Posted September 18, 2018 Report Share Posted September 18, 2018 Cant you keep the tune paired to the VIN of the PCM? I know it doesn't match your car's cowl tag but you want to tune for the PCM that's in there. I would just leave it and always use that "wrong" VIN when uploading / datalogging tune requesting etc etc Quote Link to comment Share on other sites More sharing options...
