A pcm or powertrain control module is basically a computer that controls all the setting in your engine and trans. It depends on how the pcm is programmed if it will work in your car. I did give my vin number whenever I got a pcm tuned but I don't know if that is necessary or not.... Whenever I got a mail in tune I told intense all the mods I had on my engine and trans and they adjusted the setting to match my mods. For instance if the pcm you get is set for higher shift points and your motor is stock you will get valve float at high rpm. As far as the vin number thing idk
