So It Begins- Afboy's HHO Project Writeup

[DragonRail]

I just finished connecting my EFIE and I put the A/F guage on the computer side of the EFIE. I want to see what the "end" result of the change is. (Complete signal to the computer)

bingo, thats exactly what I want. So the EIFE connects to the "sensor" wire on each O2?

My new booster should go in this weekend. The EFIE is due to arrive tomorrow. My "fear"/ issue in the past, was connecting the EFIE. I finally found a cheap place to get a complete wiring diagram ($11) and after finding the sensors on the diagram, I was able to locate the sensor wires in about 5 min. check out http://www.ahdol.com/ for diagrams..

I installed Air/fuel monitor today so I can watch the sensors tomorrow as a baseline and them monitor them after the EFIE goes in. The Last step will be to add the HHO..

What A/F meter are you using?

 

[DragonRail]

I'm using a LED gauge from Autozone..

I just went for a quick drive and decided that I want to see the actual sensor reading so I moved the A/F meter to the sensor side of the EFIE. I think seeing what the sensor is reading is a better bit of data..

I currently have the off-set set to .225v. I'll check my mileage against the readings I have been collecting for the past few weeks.. I have a 56 mile (one-way) drive to work and have been getting 20.5mpg avg on the trip .. We'll see what the EFIE will do before I continue the HHO install..

narrow ban gauges like that one are useless for accuate readings. invest in a wideban tuner like aem or inovative

I concur; a waste of effort in my opinion.

well got that new cell in today, the bolt didn't exactly mount up to the original mason jar, so i decided to make a new one, out of 4" abs, its about 6" or 7" tall. here are some pictures.

here is a video of it running ,( showing using a bubble) it does really well, very happy. this should definatlly show some improvement in my MPG, compared to the crappy old one

agreed.. those little gauges are pretty to look at but that is about it.. (what can you expect for $29)

I decided to connect the I/Os through my laptop, using some of our machine monitoring software, so I can record the data. I am more interested, at this point, with what the PCM is doing as a result of the "faked" signal..

While I'm at it, I'm going to hook into some other sensors and make some benchmarks..

we built one on a 82 F250 with a 460 this weekend i jsut used a pickle jar to test it out. it worked . the plate system didnt work for me but the plates i used wee too thick creating the terminals to overheat. So i ditched the paltes and built a coil of stainless wire and i got it to work

What about summit's air/fuel gauge?

[aldive]

Thats just another toy.

You need something like the offerings from http://www.innovatemotorsports.com/; otherwise you are just kidding yourself.

Good luck ........

I just got a catalog in the mail today from WWW.USPlastic.Com. They have a wide variety of PVC (140*), and nylon (200*) threaded rods, nuts, bolts, and washers: http://www.usplastic.com/catalog/search.asp?search=screw

Look at using ABS it can withstand temps up to ~250F

I've found ABS to be on the fragile side compared to PVC or CPVC. I've had fitting crack. They are light weight compared to other plastics. Who sells ABS hardware?

TURN DOWN AUDIO!! MY PHONE SUCKS AT CAPTURING AUDIO!! Thats my electric fan in the background running

First video is 6 cell unit. Wired +-+-+- with .5 TSP KOH. Distilled Water. Pulled around 30 amps and temp reached 130 F. Check how clear the water stays when power is taken off



Second video, same cell. Wired ++NN-- with 1.5TSP KOH. Distilled Water. Pulled 25 amps MAX, started at 20. After 30 mins of running, reached 105 degrees F. This is the setup that will go in my truck. N= Neutral plates. This uses stainless steel pipe instead of wire/plates. This results in much larger surface area.

Switch installed to turn it off and on while driving. This is to show people the results on the scan gauge.

hey i was just looking at their design, how do you fill it up with more water? does it come with a reservoir? i know those "caps" fit on their snug, but they don't quite seal, which is what you need. if you cant get into the guts of the cell how are you going to clean it?

It is a pool filter housing so its made for water and tight seals. It holds pressure just fine and sealed very nicely. There is a water in/out section (since its made to hold a filter for pools) so one side you have a filler neck, for water, the other side is the output for the HHO. I will take pics when I visit my dad later. The housing itself holds the water and the 6 cell generator. The plastic part that holds the water screws right off at the blue lid making it simple to clean. Distilled water/KOH mix hardly leaves any residue anyway so it doesnt need to be cleaned alot. The container is made to withstand temps up to 130 F. Like I said, the container is made to hold water and have tight seals so its ideal. As you can see by the output, there is no leaking. Does anyone know how to measure LPM output?

 

[Afboy143]

Here is a picture of what we have. While not the same exact thing, you get the idea

http://www.filtersfast.com/Pentek-150071-clear-filter-housing.asp

Connections: 3/4" FPT
Max Temp: 125 F
Max Pressure: 125 psi
Dimensions: 12 5/8" x 5 1/4"
NSF/ANSI Certified for Material Requirements
Pressure Release Valve

Its made to hold 125 PSI of pressure and withstand temps up to 125F. It has a rubber seal around where it screws on/off to hold pressure in. In here you make the stainless-steel pipe cell. Fits in nicely.

A flowmeter.
