2021 ram 2500 6.7 cummins
I had a dpf go out and decided to delete it. Vin was sent over when I ordered an efi live unit and am now having issues where the tune vin did not match ecm and sent into boot mode. The recovery tune will not seem to take and gives me all sorts of errors. Anyone have experience with this? How to fix?
tune was done by proven diesel

Did you have a battery charger hooked up when you did the tune? If not you may have soft bricked the ECM and may require a bench flash to recover the ECM

It should be between 13.1 and 13.9 volts 12V would be too low

I don’t have a fancy charger. Light was green entire time so I know it never dropped below 12 or light would have went orange. Problem was actually with the stereo system.
The trucks with the big touch screen and internal wifi send out a ping every couple of minutes. That ping interrupted transfer. Removed fuse 49 and 51 and tune uploaded first try. It took a trace file for the Efi live tech to eventually locate this problem.
 
What errors were you receiving? In the future turn off all accessories such as the radio and HVAC. Glad to hear your truck is up and running.

The tuning process should turn it all off, on my 19 it would kill the radio and HVAC when the flash starts to load to the truck
