EFIE module. I found a write-up a guy did on this device. He calls it an Electronic Mixture Controller. He has the complete schematic and diagrams as well as parts list for the device. I found that the voltage shift is very tiny. Basically when the O2 Sensor says there is X amount of Oxygen in the exhaust the device changes the signal by a fraction of a volt to lower that number by a definable amount. So you can tell the ECU to lean out a hair. If you pair this up with a handy dandy mixture gage from JC Whitney you can see what your engine is really doing. The plans I received build a device with a fail safe by=pas switch that turns it back to normal with just a single switch to bypass the whole thing. I like the design and I am going to construct it soon.

I now have almost all of the parts for the electrolyzer in hand. I will start construction this weekend. I surmise with my schedule it will be a few weeks before I have stage 1 built. I will post pictures and full results. Our goal s to get from 16MPG to 19.5MPG with the first stage. ~20% Gain.

Shoot. I can go from 16 to 20 just by training my foot with my ScanGuage.

Agreed, I recently just changed my driving style and have consistently been seeing 23 MPG in my 99 XJ, when I previously averaged 20.5 MPG.

I would like to see more of a technical write up on this "EFIE" device though, to see how it actually claims to work. I am still banking on Scam, but like with anything, I am open minded and curious.

they work by ineterupting the ecm/pcm signal and changes the voltage to the pcm its one of the best ways to lean out a computer controlled vehichle. I build and install h.h.o. systems my self and for obd2 cars 96 and newer its a must. i have exact schematics to build them. and also map and maf enhancers cause they control a/f ratios also.

So have you tried this with an OBD1 system? Specificly I'm looking at trying it on a Toyota pup.

Getting the Wheeling Fever
The best mileage I've gotten with my 88 Raider is 24.8. I use a homemade hydrogen cell that seems to help about 25% increase. The 24.8 mpg was achieved while doing 55mph. No I'm not trying to sell a hydrogen cell or anything like that. I built it after hearing a news report one evening. I actually built it to prove it wrong, but it ended up working. So I kept on using it. I use KOH as electrolite. There are a lot of people on HHO forums that will say it is dangerous, but then again so is battery acid and even gasoline. If treated with respect it is safe. My emissions on my raider dropped significantly when I used it while doing our gov. emissions test. I know there are people that will say it is a scam. I don't mind because I'm not trying to sell anything, the plans were downloaded FREE off the net. The cell is a dry version type which is much safer than the glass jar type. It cost me about $40 to build,and I will forward the plans free to anyone who wants them. It took me about a day to build it and the most complex thing needed is a drill. They are pretty simple to build. My original mileage was about 19 mpg. I have been using it for about 9 months. I don't use an EFIE because I eliminated the smog system on it by installing a weber carb and removing the cat. I still passed emissions testing with flying colors. It's really easy to sit back and call it a scam if you haven't tried it. Just too bad so many are brainwashed into not thinking outside of the box. There are many patents for producing HHO. Most are owned by uncle sam, the auto makers, and very amazing to everyone the fuel company's own most of the patents. Of course the would love for you to have this type of device so that you would use less fuel and cut into their profits. Popular mechanics has nothing good to say about the technology, but then again one of their sponsors on their web page was an oil company.
