    Needing help with a 2015 6.7l

    Ok, i'm needing help with tuning a 6.7l. I understand how to increase boost, and torque limits, and driver demanded torque. I need help with the timing, and fuel. How do I go about increasing fuel pressure? Now timing I know where to adjust, but I'm wondering why in some places the map is running negative timing in places where I would think coming from gas, that you would want the timing to almost be 5 degrees btdc. I'll post my tune file in a few mins. Its in a 2015 F550 Brush truck for my volunteer fire dept.

    Fuel pressure is under Fuel System/Fuel pressure. The odd shaped timing maps are most likely because of emissions.

    Cool. I'll go through and adjust it, and see what happens, then report back.

    There should be a update they can perform, I think in the IPC (instrument panel) that enables Operator Commanded Regeneration Option. It might only be on certain models such as chassis cab trucks. I cant remember.
