Ford trucks were a bit primitive yet in the early 90's and really until the 4.6L modulars came along. They definitely need a tow fuel map and an economy fuel map. That mega squirt looks like a lot of fun to me.

Interesting side note, when I am running along steady state, O2 unplugged, and I dial in more in series resistance with the injectors, I can get the O2 voltage to drop down between 0.2v and 0.1v. But at that same resistance setting if I go to WOT the O2 voltage still goes up to 0.8v. So at steady state the ECU cannot compensate for low injector voltage but at WOT it can.
