    cant read ngc3

    for the last week to read from a 2004 dodge dakota 3.7 (ngc3) i have tried it both in the vehicle and on the bench with no luck. when i read from the ECM i get a timeout failure and when i read from the TCM it saves the file but will not open it. attached are screenshots of the errors i am getting. i have allredy contacted customer support and they have not been able to resolve the issue yet. i am not concerned about the TCM but i really need acess the ECM.Capture.PNGCapture1.PNG

    That is odd. I have a 2009 Dodge with a NGC4 and it reads fine after I realized it could only read it with key on engine off lol. Hope HPTuners is eventually able to help but I personally have no ideas

    Old post, I know. But...

    Some of the NGC3s are not supported. Are you sure yours is?

    When I switched to a NGC4 I still had trouble reading. But I found that disconnecting the TCM while reading and writing did the trick.

    Have you tried selecting the TCM in the second dropdown?

    That will only work if your NGC3 is supported.
    Some of the NGC3s are not supported. And it sounds like yours isn't.

    Yes you can read these ecm's via bench harness, its the primary way we do our reads(via bench harness).
    It doesn't have to be perfect, it just needs to be done in two weeks...

    A wise man once said "google it"

    Hey bill so all ngc3 can be read by bench and are supported? I still can’t get my ngc3 for my 2004 ram to read the ecm. The trans reads fine. I’m think about swapping to an 05 computer now. Reason for this is the build date
