Yeppers. My goal was to turn the fueling into a constant, and correct fueling at all throttle settings. Only way to do this is with the AT added. Mind you, that with the LC-1, you retain the poor stock correction, only at small throttle openings, and wot., and more importantly, you cannot individualize where you want the fuel to go at what rpm/throttle settings, etc, as the preloaded maps are broad, and not adjustable. It looks to me like a booster plug on steroids..... But I understand, that if the funds are not there, it would be better than nothing.
