Ok, as a planning thing towards where this Eagle I'm working on is ultimately going: Has anyone used all the Jeep hardware from a later 4.0HO Jeep and run it with a GM ECU, I mean really most of the sensors are the same though some connectors are different. It's still a speed density system as there is no MAF, there is a MAP, TPS, O2 sensor, VSS, Coolant sensor(could easilly switch to GM version if it scales differently)Crank & Cam sensors(though I think you could just loose those & drop in a hybrid GM/AMC/Jeep dizzy)... I like that the GM-ECU can be tuned whereas the Jeep OBD1 PCM can't, at least not from my research.
