    Question Failing PCM - need migrate tune and credits to new PCM

    I have a failing PCM and I am not able to find a process that will unmarry the tune and credits from the failing PCM to allow me to migrate the credits and tune to the new PCM. I have no problem sending both PCMs off to HP Tuners or what ever process the have in place that will allow migration of my credits and tune to the new PCM. Has anyone had to go through this process or know the procedure to make this happen?

    I understand the PCM serial number locking for tune and credits to avoid people abusing the tuning process. Electronics fail and there should be a procedure in place that supports the removal and migration of credits and tune when that happens.

    From James Edwards (HP Tuners)

    The tune and credits can not be transferred over. You will need to pull a new stock read from the new PCM.
    Send that stock read to the tuner so they can create a tune from that file and send back to you.
    Then you will need to re license/credit that new tune.

    Licenses consist of three pieces of information. They tie in VIN, Serial Number and OS. If you change any of this information you will break the license and have to license the new combination of information you created. You will need to hold a license for the file you are writing as well as the vehicle you are writing to.

    Have you already got a new PCM programmed for your vin or the same vin?

    I have customers ask me often especially in swaps if I can put their say 04 tune into a new 06 computer.. and stuff like that just doesn't work that way. If your not starting with the same OS your going to be starting over on the tune.

    I know that the the new PCM needs to be programed with the vin. Then the stock tune needs to be pulled from the new pcm. Then apply the tune changes to that new stock tune file before it is written back to the PCM.

    My issue has to with managing my credits and HP Tuners licensing model and credits. I was hoping not to have to throw away the money I spent on credits for less than 1k miles on a tune. Sometimes electronics fail and need to be replaced. If the PCM fails and needs to be replaced HP Tuners license model requires to pay for credits again to tune the replaced PCM. I already talked to HP Tuner support via email and my only option is to pay for new credits to tune the replacement PCM.

    its $99.99 for credits, it would probably cost more than that for shipping both ways and labor to swap credits if they even offered that type of service.

    You adjust speedo in the ABS module on the Jtec/+ vehicles. A factory or high end scan tool is required. You set rotations per mile and tone ring teeth, 8.25 vs 9.25 diffs. I don't think HP tuners added a feature to do this on the JTEC/+ vehicles, i could be wrong though.

    If your local to NE Ohio I can change it for you.

    To the original post. I have a spare PCM for my 98 Durango. I changed the Vin using my snap on scanner to match the vehicle. The HP tuner software reads and writes to both under the same license. This should work for the 96-98 Jtec. I can't speak for the 99+ JTEC+ PCMs.
