anti tuning bb

[House]

I have had two truck these week no flash and say ant tuning bb on them.. Are these locked ecms? 7.5 said ok to flash, did not think to check v8 till now and says not to flash.
Any insight I would appreciate it!
here is the files

You can only tune cummins ECM's with v8. That is a custom Smarty boot loader that prevents EFI from loading properly. I believe you need a fresh factory flash

I flash in v8, make tune in 7.5 both trucks have never had a tuner on them according to the owners.

Even took a good file from tune depot and changed vin# and still gets the anti tuning bb

Did you read the stock file from the ECM first?

THE STOCK files are what is shown, the reads from the ecms

here is the other tune I tried to load from a tune file depot stock OS file. That showed anti tuning bb when trying to full flash v8

If you show a Anti-Tuning bootloader on the stock files...NO tune will work until the bootloader is removed, which EFI doesn't do.

Best case is load the stock tune back in.

I'll look at the files when I get to my computer to confirm bootloader, but I suspect your saying that you knew the bootloader was enabled.

I did not know it was enabled till after licensed and tried to flash it

What is the best way to have it removed?

This is not possible unless your software is old, since the start of this year it has not been possible to license an anti-tuning BB ECM.
