    Hey guys. Does anyone offer a tune without a new ecm? I've already confirmed that the dealer can confirm that the ecm had been changed and switched back to stock when taken in to the dealer if something breaks.

    I'd rather just plug and play if it's possible. Just not sure if it's possible with factory ecm

    Thx guys

    Tuning only possible with a modified PCM...and your dealer is full of shit....no way they can tell anything about the PCM......

    I wish I could agree. I've had heard face to face from srt engineers that they can, and have already proven that they can find out. I personally know of 2 cars that are no longer under warranty.

    It's not what they can see inside the computer, but how they can tell that the computer has been removed and reinstalled.

    Mod at your own risk! I'm sure FCA is looking for anyway to void a warranty claim. 5 years/100,000 is a long time for a new design. The SRT engineers delivered what they expect to be a design capable of meeting the timeline but that is based on lots of scratch pad analysis (Murphy and actual Hellcat drivers not part of that equation).

    Yes they can send it in for analysis but my understanding is none of the tuning can be detected at the dealer level....

    I meant that the dealer could not detect tuning but can send it to Chrysler for analysis where they can detect it.

    Actually they can tell if your PCM has been swapped rather easily:
    The mileage counter on the PCM will not match your odometer.
    Just a heads up.

    Things may have recently changed but according to my dealer's shop foreman (who is also a close friend) he couldn't read that info at the shop...been a couple years since we discussed it so maybe they can now....Pete (FNKYCHKN) is a tech so he can answer that...

    I checked with my friend and he did say he can read the mileage so I regress...he also mentioned he could change the mileage reading in the PCM...

    Of course they can. That is why Diablosport asks for your mileage when they take your order. And your Vin.......... The VIN and the mileage have to be flashed into the PCM before they send it to you or it will set a code (VIN does not match). The mileage does not HAVE TO match but they want it to be close if possible. Think of it this way.....what do you think the dealer does when they have to replace a PCM (for any reason).

    There are ways, other than mileage, to detect a tune. The clues are subtle but they are there.

    When I had my WRX STI I was considering running a tune. Subaru is semi lenient to a point. But one of the big red flags is Subaru could detect how many key turns your ECU had since it was last flashed. So if you blew up your engine and flashed your ECU back to stock they would normally be able to detect it and do further tests. Sounds like these Hellcats are different in that you put a completely different ECU in it? I guess putting a completely different unit in would eliminate that way as a possibility of detection.?
