Thread: HPTuners Unlimited Year/Model Multiple PCM Question

Looking to purchase HPT. I currently own a 2000 GTP.

If I unlock the entire 2000 Grand Prix year/model (for 6 credits), will I be able to use other junkyard PCM's from 2000 GP's for different setups?

Can I can program unlimited PCM's assuming they came from a 2000 GP?

If I remember correctly, it comes with 8 credits. Which means, if you buy out the whole year, you can use one other non-2000 PCM from the JY.

Otherwise, you can have unlimited 2000 PCMs.

Yes, you can tune any grand Prix PCM of the same year.

Thanks guys!

I assumed it was do-able, but I wanted to be sure. Local JY charges $35 for a pcm. I planned on having on for E85, and one for 91. Also have a buddy with an '02 GS. Is there any reason an '00 GTP PCM wouldn't work in his car?

The PCMs will swap, but you will need to purchase credits if you go the route you planned.

Or you can unlock your car, the JY PCM, and then your buddy's car and still have 2 credits left for misc purposes.

Or you could just find a used dhp? Which makes more sense if you don't have an 06/07

If you have DHP, you can flash just about any w-body for free once you unlock one PCM.

I was actually looking into doing just about the same thing as OP. But when I Google dhp for sale I can't seem to ever find one. Any advice on where to look for it? Anyone on here selling?

dhp's are a bit hard to come by. you need to keep looking at ebay, cl, any gm v6 car forums, fiero forums.

Just bought HPT Pro on Friday. Picked up a second '00 Grand Prix PCM yesterday. Plan is underway.

99 and 01 are different pcm's part numbers, could be why. i do have my 98 on a 01 pcm. but that dont always mean they will work.

when i did the 01 pcm in my regal i did it in the car, and then it went into the compatibility mode window, then i had to pick a years and engine combo that matched my car. and it went fine.

that compatibility window has not come up on the off board. nor have i been able to make it open up again. so im thinking when you switch a pcm with non matching part numbers it should be done in the car.

maybe if you put the pcm back to the 99 bin, then try to flash it in the car, it may work better if the compatibility window opens up.
