I've had a complete C950 race setup sitting in a box for 6 years now. I recently had to swap to a carb and I can't stand it. I need EFI again.

I got a C950 wiring diagram from the Holley website but I still have a few questions.

I have a ZT-2 wideband I want to use with this. I guess I would input the wideband signal to the purple O2 input on the C950 and then select the WB option in the software?

Will this C950 run 4 GM TBI injectors? I assume so but I'm not converting to EFI AGAIN for nothing.

What about the 2 IAC's? I plan on using a dual quad carb intake that has the separate runners for each carb so I'll have to use 2 IAC's. Should I just wire them in parallel?

thanks!

on the crossfire cars, the IAC's were tied in parallel, and in the code, the step sizes were half what a single IAC was, if that helps any.

can't help on the injector side of things. I would venture to say probably not able to run 4 PnH injectors.

Well, AFAIK the 950 will run the Holley 4-bbl TBI; which is nothing but 4 Chrysler injectors. So it probably will do 4 GM ones, too.
