Let me explain what I'm tryin to do. When I done my heads and cam a couple years ago I had a mail order tune done because I had no way of tuning it. I ended up just buying another pcm from the tuner so I could still drive the car while the pcm was being tuned. Well as I have learned a mail order tune does not work so well with larger cams. I have sine bought EFI Live and have got it tuned perfect. Well since I have this other pcm I was just gunna flash it with my current good tune just to have a spare in case something would happen to the one in the car. So I hooked up EFI Live and went to flash my tune in to it and it says the VIN isn't lisenced to my cable. So I looked and the spare pcm has a different VIN than the one in my car and the cable. So in order for me to flash my spare pcm do I have to spend the money for another liscense? That's crazy because it's the same car I thought I would be able to flash the correct VIN in to the pcm but I forgot I can't flash it. Is there any possible way I can get my VIN in my spare so I can put my tune in it if I need it?
