Holley Projection on a 258

[73CJ]

Is anyone running a 1D Holley projection fuel injection setup on a AMC 258 i6 / 4.2l ?

I'd like to compare notes.

I believe they have a few on www.Jeepforum.com not to steer you away but have seen it metioned there.

Follow his link... I run a 4d on my 390, not quite the same though.

it seems to work on a lot of engines and can be made into a closed loop system which is nice

I'm running closed loop now. Just wanted to compare notes.

Thanks Guys

I just bought a 78 CJ with the AMC 258 i6 / 4.2l and it has the Pro-Jection 1d system. It ran for two days now nothing...I cant speak of the system as I dont know how old it is or who installed. I will see tomorrow how good Holley's customer service is! Are you running with it?

Ran Pro-Jection for along time on my CJ, it worked great.

I've got 1400 hard miles (maybe 200 on roads). Runs good but I keep tweaking. No stalling. Starts right up hot or cold, winter or summer.

Running a digital air/fuel ratio meter for fine tuning.

Just an update. Replaced injector mod, tps, fuel pressure load cell, temp sensor. Adjusted fuel pressure to 16 PSI, TPS to .75v, returned all pots to null except mid range (1/16 turn cw), accelerator pump (1/32 turn cw). Seem to run great. Acceleration is poor but I hope I can adjust mid range and power up a bit. Very pleased.
