Thread: Using a temporary PCM

I am getting ready to drop my L67 in my 99 GT and I have to send my PCM off to intense to upgrade it for all of the mods I have with the new motor. My question is can a use the pcm out of another 99 gt to send off to them or can I run the spare one briefly while I waite for the one I send off to get programmed to come back. Intense told me not to use the 98 GTP PCM I have because my other computer would communicate with my BCM better than the 98. I have another 99 GT PCM and I could probably get the BCM that goes to it as well if needed. Any advice would be greatly appreciated.

Have you gotten your answer? I don't think you will be able to use a different PCM because of it not matching to the BCM. But even switching both of them it may not work. I tried that with my 04 and it still would not start even with a case learn. But you are able to flash another PCM with your info and it will work. Basically copying your PCM before you send it in. Hope this helps if you haven't got it done yet.
