I thought about it for one of my projects but that's a long way off. To get an accurate reading for both fuel injection an ignition you need a crank sensor and a cam sensor. At least that's the way its done on modern vehicles. It looks like the FAST system is just for fuel. Not sure about what the Holley dominator EFI either. I haven't schooled myself about the all the different systems that are out there. Why i mentioned the megasquirt controller is because i seen some people run the second gen ram trucks with it(and others) with a turbo(or two) and they need a crank and cam sensor to work both fuel and ignition if you remove the original controller(PCM). It's not self tuning but once it gets dialed in it should work perfect. I would think using one controller to do both would be better. With the the separate controllers one doesn't know what the other is doing. Well at least that's my theory.
