…….As it happens with many subjects, get enough silly old darts (SOF) and any subject can get twisted into a pretzel. Hey and if you blindly follow all the stuff they tell you that must be done your coach may never run again!
Such has occurred when it comes to fuel injection…..why we have it and why you should consider it. So many more misnomer….how about we try and clear the mud out of this:
When someone says, ” I used this one, you should too”. That’s not a recommendation based on anything other than he hopes he made a good decision and wants others to be in his handbasket as he finds out where he’s going! Get more input…..and when someone says, ” That other brand is a total piece of crap, it failed on me”. Again that’s a personal bias because something wasn’t understood and I couldn’t make it work…..seek more competent council!.
Now, what you need is someone who got through the integration of the unit to a 45+ year old drive drain design and got the system to work well. His journey is the one you want to pay attention to.
Someone said the FiTech is Crap and the Sniper is everything. Wrong there space ranger….. They both work well by virtue of just what it is….a microprocessor controlled, learning, active pressurized fuel injection system. “Self learning is the key less than the hardware.
I WILL tell you when using the progressive linkage option on the Sniper, your ported vacuum output needed to power your distributer vacuum advance only works when you gag the maggot. Personally I feel both system firing full time 4 injectors controlled is a more direct system. I mean all were doing is spraying atomized fuel into an air hole!
As anything new there were unexpected results from integration of 2 so age different devices but perseverance prevails and we now have the bug out both Sniper ANF FiTech offer superior performance over the spring loaded salaries of air and fuel leaks spray gasoline out of a Windex sprayer carberatprs…..the problem to now solves is adapting to the fuel formulations……..that’s why carb performance, especially when you tax the system….it can’t atomized the “cold” fuel…..THATS why you go active fuel injection. Not this brand over that. Please follow the right lines of thought
Not a flat floor..they both do that, not rare of install…most can install either and it’s not the ability to connect it to the distributer control….keep your diagnostic tree start at “fuel” and “fire”. Connecting them good luck finding problems….its really does not help performance, mileage and your gut won’t shrink so why expose yourself to that!………..
A key we have found is with a float bowl in a carb acts as a small “resevoir” to keep fuel flowing the the jet even when the tank causes temporary loss of fuel to the pickup during curves that cause excessive tank slosh. That solved, the steel tanks insert small rust particles into the fuel, most stopped with filters but fuel injection is as much or even more reliant on a clean fuel delivery. Our 45 year old steel tanks sometimes have a hard time doing that. The more integrated the more chance of “ghosts in the machine”.
I hope this has cleared up some confusion, I discount any comment that says a nationally produced product with a viable business backing it is junk….you should too…unless it’s just the wrong dang part…..like 80mm calipers……so let the good fight begin!
See ya tomorrow

Good on ya, Jim. That needed to be said since the dawn of self-learning EFI. I got scalded by a handful of “experts” just after I made the presentation on the FiTec system at the GMCWS rally in Coos Bay, OR, that you attended. The nock the “experts” laid on me was their contention that FiTec could not control spark (it can), or that it’s spark control was too “crude” to be useful (it’s not).
One point I think you should touch on is users trying to eke out one or two MPG by forcing any of these retrofit EFI systems into lean cruise mode (advanced spark and lean air-fuel ratio). They may get away with that in flat land with no front wind, but that can quickly result in elevated internal engine temps while driving in mountains or into head winds as many GMC owners in the mid- and far-west encounter every day.

I thought that would happen….i run away from integrating the spark…..keeping it segregated the old. …….do I have fuel and fire? Diagnosis ……integrating them its replace parts time. I really have moved away from caring what anyone says…..i have learned what I know lagit! Thanks for the reply
