That is a VERY interesting interpretation of the acronym. I love the way you think.
Seriously, I skimmed over the links that came up (nice job on that BTW) and didn't find anyone that actually understood the EFIE technology (except Mike and I). I know the EFIE 'works' (as in does what it's intended to do) because I started from the very beginning and worked my way to where I am now (it took years).
It's also important to note that the EFIE is NOT a fuel saver and I've never claimed it to be. It is an interface that allows actual fuel savers to be used on EFI engines. Your fuel savings is determined by the effectiveness of the fuel saver, not the EFIE. This is easily proven by adding an EFIE alone and seeing little or no gain. This simple test also proves the skeptics that think it's the EFIE that is saving fuel WRONG!
The EFIE was developed because fuel savers (HyCO 2A and the HyZor), that were working fine on carbureted engines, wouldn't work on EFI until the oxygen sensor signal was addressed.
ecomodders can start where I did and monitor the voltage signal from their oxygen sensor (best to use a high impedance analog meter with a 2 volt scale, digital meters tend to jump about a lot as the voltage signal varies quickly and often).
If they watch the voltage while turning on combustion enhancement technology that actually works (like the HyCO 2A or HyZor) then they'll see the effect I described before, where the oxygen level rises in the exhaust (voltage goes down), and then the ECU adds more fuel to compensate. It'll help if you have some type of meter that measures fuel consumption at the same time so you can see the real time effect. I have a special circuit that I connect to a fuel injector, the scan gauge may do as well.
For anyone who wants to give the EFIE a real try, I'm here now and I'm willing to help.
EFIEs are now being sold by multiple people in various versions. Be sure to get a version that's appropriate for your vehicle. My EFIEs are optimized for the original narrowband oxygen sensors, up to about year 2000 (and beyond in a lot of cases like both my 2003 RV on an E450 chassis and 2008 Aveo still use narrowband O2 sensors).
A KEY thing to note that although oxygen sensors really haven't changed much, ECU programming has! For example, I have no proof it's because of the wild success of my EFIE, but they reprogrammed the ECUs to 'recognize' a floating voltage offset and to either compensate or go into open loop.
A portion of O2 sensors also switched to 'wideband' and to 'frequency' output (instead of voltage).
For more modern O2 sensors and programming, your best source (in my opinion) is Darol Mason (
klondikedarol) on eBay.
Which brings me to something I've noticed about ecomodders on this site. They seem to concentrate on vehicle modifications that do not involve combustion enhancement technology. That is excellent and needed but definitely limits the potential for fuel gain. There is a whole world of possibilities, some of which are fairly easy to achieve, if you increase the combustion efficiency of your engine/fuel.
So here's a start. Did you know that,
for internal combustion, the
14.7:1 air fuel mixture is a LIE? Yep, I expect to be flamed but try to keep an open mind when you [link removed by admin].
