crossfire to tbi conversion...
i am about to fire up my 1982 transam wich used to have crossfire injection. I have just installed a holley tbi intake manifold an a holley 670 2-barrel tbi. the wiring harnesses for both of these systems (xfire and tbi) look almost identical except the xfire harness has two idle air control connections. should this system work alright or should i put a real tbi wire harness and computer in?

It should work just fine if the pins are the same all thay did on th IAC's was split the harness. Good luck By the way do you by chance still have the spark controler from the cross fire system I need on badly. Thanks Dave

The CFI IAC controllers are just wired parallel, leaving one off won't matter.

Well the engine runs...
It seems to be running incredibly rich however. I thinks the plugs are fouled. I have set the timming and have everything hooked up properly (I think). I havent worked on it in a while but im thinking maybe The tps needs to be adjusted or the fuel pressure regulator (Holley tbi) on the tbi needs to be turned down... I dont know. Any Ideas?
