    I know that this thread has largely been devoted to V6 applications, but has anyone heard/seen anything regarding F134 applications? I've particularly been pondering the viability of a 2bbl sniper setup.

    Scroll back up a few pages, I talk about it. MSD tech says it should be fine.

    I’d think so long as the EFI system you use cant be triggered by the oddfire to invoke accell/decell modes constantly, you’d prolly be ok with stock trigger. IMO a wheel will likely result in the best situation most of the time.

    After weeks of waiting for an oddball M12x1 tap to make the bracket for my magnetic pickup I fired the jeep up a couple days ago. It then took me some mucking around with figuring out where to put the pivot point on my throttle linkage to get it throttle response correct. 2:1, toe movement:carb movement seems about right. 1:1 definitely does not work. The Jeep runs great, cold start got better and overall response is better than back before the TB knew what the RPM was. Its like a new vehicle.

    The magnetic pickup was easy to mount. It threaded into a homemade flat plate attached to the fuel pump blank-off bolts. Its sensing bolts with little tabs welded on the side stuck in the holes on the dampener pulley and wired easily into the Holley.

    I'm just gonna throw this out there as I believe some may be over thinking things a bit. These are not 'port' injection setups, they are Throttle Body injections. If the timing of the valves opening and closing was so important to the fuel being 'injected' a carburetor would have NEVER worked. All you are doing is putting atomized air/fuel mixture in an intake manifold to be sucked in when the VALVE decides it needs to be sucked in - just like a carburetor does.

    I have run the EZ-EFI, and the Powerjection II setups from the HEI tach signal. The FI-Tech is running across the street with the HEI Tach signal. I have the Summit version to install on the '63 Build - again, running off the HEI tach signal. None of these are dependent on the timing of fuel squiring in sync with the valve opening - and they work just fine.

    If the ECU your using is having a hard time with a filtered or basic signal - I'm not sure I'd want to have something that picky controlling what is essentially a carburetor function on my wheeling rig.

    Not after you build the manifold system to support port injection - and buy 6 injectors, possible coil packs, high pressure rail system, and ... :banghead:

    I’m quite interested what a FHead will do once the fuel side limit is removed. Be nice to also test the same with the clifford header and a vac distributor.

    Obviously top end power shouldn’t be a pronounced goal, but a significant mid range power improvement could be a neat finding.

    well just pulled the trigger on the holley sniper 2gc efi. Might be quite some time before the install but will keep everyone posted.

    Based on your username, I'm guessing it's for an oddfire? Are you going to do a crank trigger for a consistent ignition signal?

    no, according to what other people posted, all i need is a tach signal. I'm running an HEI so tach signal from that is all that it needs besides + and -. And yes I'm running an oddfire.

    I'm very curious how well it works. I want to do the exact same setup pending funds and time.

    I'm curious as to how this goes too as it's the way I'm planning to go in a few months.

    I really am beginning to dislike this thread as I feel it will eventually cost me roughly $1200.
    My jeep runs really good. Super reliable setup..... but then there's this scary voice in my head that tells me I should get the sniper efi....... I fight it off telling it that....I don't need any computers or electronics that could possibly let me down in the middle of nowhere.... Scary voice comes back and says.... How do you know you wouldn't like it...... :banghead:

    Do you have EFI or a carburetor?
