Hey guys so I made a tune file for my 2012 6.7 cummins.
Here's what I modified:
Main Timing: Max 23*
Duration: Added 25% to the upper cells then blended it into the surrounding cells which gives me a max of around 2700 us
Rail Pressure: Smoothed with max at 1850
Post Quantity: Zeroed
Timing Earliest Limit: Set to 50*
Timing Latest Limit: Set to -20*
When I do a WOT run, I get the codes P020A-F which are injector 1-6 performance codes.
Only on this tune do I get these codes. I'm not sure what it could be. Any help would be great!
I feel like it could be a rail pressure problem where it's not getting enough fuel to the injectors to match the commanded fuel values which triggers the code. Can anyone verify this?
