Just out of curiosity, does this box have a limp home for the transmission. First off, a bit about my setup. I'm running a Megasquirt II as my fuel/timing box, then I'm using this to control my 4L80E. I have tapped the grounds, power, TPS MAP and tach signal in order to get it to shift. I took it out on a quick test drive, and unless I'm nuts I have more than second gear which was sort of what I was expecting.
