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.Quote:

Nov7th update here
I ran into one today that would not even take the h&s original xrt to kill the anti tuning bootloader. The ecm was recently replaced by the dealer. I thinks its due to the outdated xrt I use to bypass the bootloader. Time to shop for an xrt pro. With your busy schedule, Have you attempted to resolve this issue yet Ross?
I just opened up both of the files posted in your opening post...and both show DO NOT FLASH in the Boot Loader section of the Calibration folder in V8.
When you read the files from the ECM you would have been taken to this very screen to save the files...and you should have clearly seen this warning.
Thats why Ross/Paul put it there.

The only way to recover the ECM back to working order is to flash the stock file back in.

I have been looking for a simpler solution that does not involve needing to reflash the ECM bootblock.Quote:
