I can't give you specifics on Bill's software yet (hopefully by next week), but I have been inside and out with the Sniper Delta Force software.
Ford in their infinite wisdom decided that having specific parameters that are tuneable would be too easy so the Ford PCM actually uses many different ways of controlling different outputs such as "line pressure". The 95-97 automatic parameters that I have to work with are few and far between. The "torque table" is a pretty easy way to firm up shifts across the board. However, TV (throttle valve, which is OLD school mechanical terminology) pressure is the shift pressure in relation to APP (accelerator pedal position), so there are two ways....then there's a "solid state" TV variable.....
"Injection timing" is another one of those "more than one way to skin a cat" type things.....and there are a lot of ways to do it.
It's a lot to get your head around!
