    Exclamation 2014 2500 won't start after efi install. Error $0371

    Unlocked my 2014 with the bullydog and then proceeded to install efi from anarchy. Unit went all the way to 99% and upon completion I received the error $0371. I've tried reflashing multiple times with no luck. I've unhooked batteries and then tried again. I have tried the flash with and without a battery charger attached. Has anyone ever seen this error or had this issue. In the instructions it said if the ecm has been unlocked already then I should skip the step of licensing the ECU but the unit doesn't allow you to do that. Any help would be appreciated.

    What does the auto cal or v2 say underneath that code?

    That code means the transfer of the tunes from your auto cal had been suspended, or not completed the flash to your truck.

    I would contact your tuner because it is a good possibility you need a sock file to flash back to the truck, or the Bully Dog did not complete it's job.

    I think your tuner will have to send a recovery file. Then repeat process.

    Thanks for all the support guys. Anarchy has been working with me through email. They asked that I contact bullydog and check everything over with them. After 2 hours on the phone and going through the unlock process again bullydog says the truck is unlocked as it should be. I've tried the autocal again with no luck and have contacted anarchy once again. Hopefully we can get this figured out. Going on the third day with my truck down.

    Does your truck have the 68RFE?
