So this rig also has Holley ProJection.

My question is which system is this so I can download the proper manual for tuning purposes.

Thanks everyone,

Jared

I think that is a first generation projection box. It's analog open loop. Dan Gregg is running one and Walt Halley had one.

Wally is correct. I also have a spare controller and tbody for mine, as these are old and not produced any longer. Parts are available fro Autozone and Holley. Holley has great customer service. I have called them twice and both times they solved my problem over the phone. Teri and I are traveling today but if you need anything email me and I will help you when I get home. gregg_dan at hotmail.com.
Pretty much trouble free. I replaced one tps and one of my throttle bodies began sucking air somewhere so I just swapped in my spare.

Dug through the box this AM. I dont have the install manual, but I do have the one for the closed loop o2 sensor [it was an add on option]
I have a hard time seing the dashpots on yours which I take is a 2 BBL
mine has choke, idle, midrancge and power1 power2
If you are already hooked up and running I can walk you through how I tuned it. Its really very easy if tou have a tach and a vac gauge. But a wide band is ideal.
If you want the manual though, you will prob need to call Holley.

I had installed the Holley Projection 2bbl on my gmc back in 1993. I used it for several years but then replaced it with the computer controlled Howell kit.
I later sold the Projection on ebay for $300 but my manual went with it.

I do have a manual for the 4 bbl version in my files and I can sent a .doc or a .pdf if anyone wants it.

Emory, I would greatly appreciate it if you could forward that as I do plan to use mine but on a non GMC. I labeled the connections but 10 years in storage and I can no longer read them.
