Holley Pro-jection

I'm going to look at an 85'CJ-7 with a 258/I6 that the PO installed the Holley Por-jection on. I've been reading up on it in searches, but would like to know if anyone here (Hammer) has any real life experience with this setup? Good or bad. Thanks for the responces.

I think that if you do a search, it has been addressed (and i think jeephammer chimed in on it), I know i have looked into TBI and when i get enough coins Holly projection is my choice.

Which system is it?
I have been told to go only for the digital systems with the oxygen sensor.
Two local Jeep club members are running the 502 system with the 2 barrel TBI. One guy loves it, and his Jeep runs insane up and down our local trails, he bought it used off ebay. The other guy purchased it NEW and had nothing but problems with it.

IMHO I would still take the fuel injection over a carb. Test drive the Jeep, see how easy it starts both cold and when warmed up. Keep an eye out for smell of raw fuel comming from the tailpipe. Running rich was my buddies problem, even with the oxygen sensor. The Howell kit is a take off from chevy and should work well.

Not sure of the system, the guy emailed me back and said he was going out of town for a few days. He didn't really answer any of my questions, except for 15000 miles and it was mostly towed behind his PO's RV.

Well, just look it over and as with anyting, abused stuff = money and headaches.

BTW, you put a V8 in your 80's cj recently (picture of post about power brake vacum)?

I run the digital system (2bbl) on my buggy.. love it. I've had it on the engine (SBC 350) since 2002ish. I make minor adjustments to the CPU when the weather gets cold and again when it warms up.. nothing major. I don't even have the "closed loop" setup.

One thing to be wary of is water. My Throttle Positions Sensor died after a deep water crossing. I also fried a CPU when I accidently hit it with the pressure washer after a mud bog.

As for running rich.. I know the V8 version has 2 ways to connect it. One for a Big Block and one for a Small Block. If you hook it up in the Big Block mode on a small block, you may not be able to lean it out enough.. causing a rich condition.
