    Builds 1985 FJ60 Gets a Holley Sniper EFI Setup

    keep in mid there's a setting in there, that affects the reaction rate of the unit to changes sensed by the O2. 1-5, 1 being the fastest. Its there to compensate for O2's that are far awya from the intake, and comes factory on 3. if youre that close to "good" with the rpm at 680, try moving that...

    yea.. v8 has been a plan now for... i... dunnknow... 8 years... i guess too lazy and too cheap. i actually bught a rust free 62, as the 60 is just too far gone now, for my taste, so im gonna move the drivtrain and tons other parts and run the 3fe for a while and see if i like it.

    A couple additional things i'll note that were fighting here, is the amount of RPM band were dealing with, and volume of air required for the power produced. first, the sniper (at least my "2bbl" model) comes set up, and is expected to be utilized, on an engine that has 40% more usable rpm. I...

    Here's what I've wondered... with a carb the fuel is a constant flow with the venturi effect, and with a FI you're pulsing. What effect does that have at what RPM when combined with the manifold? I think at high RPM it doesn't mean s*** with the volume and turbulence, and thats why even when...

    naa.. thats fine. its just idle, and that fuel will keep the o2 from hunting around and going lean with the s***ball uneven airflow on the 1930's manifold design when you come off a long slow deceleration. keep in mind if you put a modern oem engine management system on this engine, the airflow...

    starting and running sideways are definite advantages. in really cold weather you are on the go much quicker when finally tuned. think of it this way, if merely adding FI added MPG, they wouldn't have had to redesign entire engines. that having been said, the engine will generally run smoother...

    my angle sensor is a little bit over perpendicular, and i have 3-2-1 headders so its under the driver where i could get a drill in there. further away than ideal. i was too lazy to drop anything.

    ill download and take some screen shots of my settings when I get home. I'm not stock, but unless you did something really wacky, I cant see that killing an O2. THink about it, you're getting "normal" reading and its running fine, why would an o2 s*** the bed fro the exhaust? I lost the stock...

    Just an FYI, or, maybe just my opinion/observation. This product is marketed as self learning and plug and play. It sort of is when compared to older Megasquirt and such, but, it's not AI. It doesn't magically know whats going on with the condition of the motor. It shows up with a fuel map that...

    fj62 split case parking brake

    Are there any other options besides the TSM unit most seem to be retailing? They have a supply chain issue, most retailers appear to just drop ship them, and theres a lead time that is messin' me up.

    Fj62 3fe exhaust options.

    It seems to me the part than makes cleaning up the exhaust into a tidy 3-2-1 inside the frame rails, is the distance the O2 sensors are from the engine. That's as far as I've ever seen O2s mounted. In fact, I have a Holley sniper on my 60, and when far away you have to make adjustments to the...

    I would say, one of the most important things to do is adjust your valves. Issues there may just show up as a slow degradation of power on a carb, but can cause real fuel issues with an O2 sensor. It tuned out much better after doing my valves.

    That’s spectacular. It’s tough to find a shop that does custom pipes anymore. Having a pic is a thousand words.

    Ok, that’s on a 2f. This is a stock 3fe and I was looking for a solution that kept the O2 sensors.
