Thread: pcm questions?

hey you guys was just wondering, Lets say I buy some ones zzp pcm off them. Do I need to have it programmed to my vin numbers?
Or can I just put plug it in and go?
Because people have told me ya just plug it in it will work and others have said dont **** with it its gotta be programmed to your vin

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

oh I know that im not a noob, but was just curious about my vin. would not haveing my vin programmed in be a problem?

good point bro

As far as I am concerned it doesn't matter, usually as far as I know it's to make sure the PCM reads the same vin as the car for smog and such. I have switched a couple of PCM around and work fine without issues. Just make sure it works with the year you need. Like 98-02 I believe is the same gt or Gtp 97 and 03 are different.

Doesn't mean it was tuned. Most likely it was. But ya never know. Although an extra pcm never hurts anyway. Did the car have a modular pulley?

IIRC they did it for warranty reasons... Because, if the vin numbers were different it voided the warranty. Dont know if that is still true or not but thats what I remember way back when they did mine (literally ~6 years ago).
