Do those aftermarket systems run closed loop, or is there a way to make them run closed loop? I have a very "general" understanding of how this stuff works, do the aftermarket systems eliminate the need for O2 sensors and all that stuff, or will a MAF or MAP sensor need to be added as well as O2 sensors. I assume that the old engine would have used at least a MAF or MAP sensor, which would probably be interchangeable between systems, but if O2 sensors are required, you'd have to drill into the risers or somewhere.

Please educate me on this I know pretty much nothing about aftermarket systems.
