EFI Issues

Deleted my truck today and while loading the tunes from the EFI it timed out. I gave Anarchy a call and he asked about the unlock process. I told him I’d check it and call them back. I’m using a BullyDog GTX. It said the unlock function cannot be found BullyDog says that means the unlock has already been done. Which I can agree with. I tried to run the EFI again and got another error. Unfortunately I didn’t copy all the error codes down. Now my BullyDog has a white screen and neither the EFI or the BullyDog can read my vin number.

Error codes: 053E, U1601, are the ones I did copy.

Anyone got any pointers for me?

The truck it’s self has a lot of warning messages. Over heat, Amit lock, electronic brakes,

In case anyone else runs in to this, it’s caused by the info being erased off your truck. You need to load a stock tune back in to your truck. Once that’s done you can load the custom tunes. Anarchy is top flight customer service.
