I say "hybrid" because it is a limited amount of power that I will be getting from a source other than gasoline. That source is Brown's Gas, or HHO. For my chemistry final at my high school, my friend and I (he's also a fellow Jeeper) decided to do a presentation on alternative energy. After reading the Water4Gas website, we decided that we thought that we could use hydrogen and oxygen to improve fuel economy. We installed a prototype system in his sister's 1990 Ford Escort and got the mileage from 31.0 mpg to 37.4 mpg. Today, I built the electrolyzing part of the system for my Jeep. This weekend, the install will happen and I'll post up some results on mileage gains (hopefully...if not I'll post whatever the results are.)

Good luck bro! Hope all goes well.

[goldswim5]

good luck with this, i cant wait to see the results! I've been thinking about doing something like this.

That sounds awesome. My cousin in law has been researching some crap about that, he got a little toyota paseo (45mpg), and thinks he can mix in water to get like 60+mpg. Keep us updated with any improvements! ([dream] You could sell your units and make millions, and end all mpg discussion threads![/dream])

That is a nice dream...... by the way, my milage has been going.......

i built one for my 01 and installed it a few months back. it worked really well until the ECU detected the extra o2 in the exhaust and richened the mixture and dropped my mileage back down. i'm looking into simulating the o2 sensor to trick the computer, but i dont really know what to do. that would be the only issue to watch out for. as soon as i can get that problem fixed, i'll post my results. keep us posted on your work too and post pics if you can get some

also, if all you're gonna do is talk crap on this thread save your breath. don't flame!!!

[KevinR]

Yeah...o2 sensors are my worry too. In reading about I, you can vary your MAP sensor by changing the resistance and trick the car into giving you a leaner mixture. I've also heard that wrapping the o2 sensors in foil tricks them. I haven't personally tested either, but I'm putting those ideas out there as that is what I have read.
Best of luck

You need to run an EFIE. You can buy one off ebay, but there not too tricky to make if your slick with a solder iron.

If you don't do this your jeep's map sensor will compensate and you will actually get WORSE mileage.


Be smart and do not forget safety... flashback valves are your friends.

ive been reading up on the water4gas thing it seems like 1 out of 20 people say its a scam, but that one person has never done it lol curious of this also

[65thTJ]

This water4fuel is different than water injetion right? It'd be nice (as a side project to your project) to take the computer and get it reprogrammed to run lean and then run a water injection system like many aircraft engines have used for years to get more hp/thrust. Basically the water does 2 things. It acts as a cooler to prevent detonation, and also expands in the gas form to creat more power.

Def. interesting though!

[bman9089]

interesting. I've been reading up on HHO.

That's pretty crazy for a highschool final.

These boxes you solder into your map sensors are what are commonly referred to as "map clamps". They effectively changed the air/fuel ratio by changing the signal sent from the map sensor to the ecu via an adjustable resistor. The stock ecu adjusts fuel according to temperature, elevation, exc. A map clamp simply makes an ecu believe it is taking in hotter or colder air to run more or less fuel. This is calculated by the map sensor. They can be made entirely of products found at your local RadioShack, however an ideal situation would allow for a wideband to read an accurate air/fuel reading to properly tune. It is not the most accurate, and eventually can lead to the ecu detecting a bug and throwing a code, but it gets the job done. A factory ecu (even obd II) will only add so much fuel over the stock fuel curve so when modifing a vehicle it is necessary to adjust, otherwise modifications are not as affective and add little to no power. That being said, when it comes to serious tuning and heavy modifications map clamps are generally considered half-*** and often laughed upon by serious tuners.

i read on another forum that if you do MAP adjustment thing, the ECU will eventually "learn" about the modification and change the mix to account for it to bring it back to the curve.

i want to do an EFIE, but i have almost no clue about electronics and would not want to install some POS thing i made with a chance of frying my ECU or something...

very possible, as you are not actually changing the fuel map but tricking the ecu to... In an ideal world you would run a piggy-back type (Apexi SAF-C) or even better a standalone engine management. On my RX-7 I run a Haltech E6k standalone. Most cases require a vehicle specific fuel controller to mate to each vehicles wiring harness, but there are some "universal kits". I believe Halteck makes one.
