Hello All,
We were working on a ppei custom tune. We loaded and got error code $0340. After hours of reading we know we have to flash back to stock, even found the stock files in the threads. Not sure which we need to load to restore correctly.
Using EFILive V8 (we were told no unlock needed tuner would handle)
CME CM2350B Cummins DieselECM
68RFE Trans

The files from the stock tune library, said they were not correct for the V8 EFILive Scan and Tune

Any help would be amazing truck is dead in the driveway on a holiday weekend.
