Fuel Pressure control definitions

[Scott@FP]

What is Feed Forward tied to in the FP Control parameters? Injector DC%? Injector PW? Efficiency?

I'm using FP Control to attempt to do something goofy, control air pressure, it works pretty good but is a bit slower to react than it should be, may need some Feed Fwd/Normal Position type help. Integral limits have to be near max allowed (-100%, +100%) to get final error out across the entire aim range.
