EFIE and / or SENSOR EXTENDER

[PAPAFIXIT]

This HHO thing is WIDE OPEN for scamers.
Has anyone seen or heard anything credible about OXYGEN SENSOR EXTENDERS? Should they be used with an EFIE? Do they work at all?
They're cheap enough ( $7 - 10 ), but is it just more BS?

I wouldn't trust anything that messes with a sensor without doing a baseline dyno using a wideband o2 sensor to monitor base A/F ratios, and then running the same dyno with your HHO setup added and what not. I think people that fiddle with the oxygen sensor readings without monitoring their actual a/f ratio are just playing with fire.

Thanks for your opinion, I am more than a little nervous about trying to "fool the computer" because someone obviously smarter than myself designed it.
COMPUTERS DON'T BELONG IN AUTOMOBILES

I have researched this online and just can't find a clear account where someone has actually measured this. Those selling them say they work.

Personally, I'd like to electronicly change & control the values instead of living with what a spacer may offer. That way I'm in control and can quickly change if need be.

Phantom is totally right about the wideband setup. Being able to actually see the A/F ratio is the way to go. But you don't need a dyno a simple drive around town would do it...... alot of people don't have the cash for a wide band setup though..so alot of people use thier butt dyno to test it when the mixture is too lean the motor will stumble ..so they lean it till it stumbles then rich it up just a hair. which I agree is not the best way to do it but I have several people do it this way.

lean it too much and you will ping to death...

i have this on my 4 banger kia, but am afraid to put it on my 610 RWHP Lightining..

i will definatly be on the dyno getting it tuned for this if and when I do go ahead and put it on my truck..

anybody have an HHO machine on a boosted vehicle?

how bout using an engine programmer to change ur air fuel ratio, like the bulldog mentioned in another post?

do those change all those setting like that?

[porkchop]

gasmaker- how would you "lean it out" on a fuel injection? Not trying to be a smart aleck, I just don't know how to. I would like to do the drive test & engine stumble method you described.
Anyone- why would extending the O2 sensor help? Wouldn't the O2 remain the same inside the pipe?
- would you have to go to a auto shop to have the A/F mixture changed (on the computer) to enhance the hydrogen generator? Could this be done?
- what exactly is an EFIE? Seen a lot about this, must have missed an explaination when reading through this forum.

It might be a good idea to have some sort of glossary/definition page for us beginners. Just a thought.

This might work on my Ford Lightning if I go that route... I use SCT to tune and program the trucks computer... my thing would be to build a throttle switch and have the current shut off to the bubbler with anything over 40% throttle, and I would tune for it too..

you mostly want to tune for cruising for best MPG results...

I think this is probably the most critical area that needs the most research. Based on what I'm seeing, we are able for the most part to get hydrogen production. Where its effectiveness will be made or broken is in the control of the air flow mixture and take advantage of the HHO. The production of hydrogen is the fun and most visible part and there is plenty of tinkering going on in this area. Where I think we are falling short is really making sense of what we can actually do on the electronics side. This is also where we have the biggest long term challenge. We may get fuel economy but if we over-lean the mixture we could damage the engine. We need some good boundaries there. Clearly those working pre-electronic fuel injection - via carburetors do not have the issue but for the most part we'll all encounter fuel injection in one car or another.

I'm suggesting to the forum managers that we set up a main sub folder on "Fuel Injection Management" and let's start collecting the information in one place. It keeps popping up in different threads but this is as important as plate configuration or any other main area of HHO. We are getting bits and pieces on HHO Extenders, EFIE devices, and actual adjustments to the computer controls themselves. It would be good to get some auto mechanics that are interested in HHO to weigh in. I know a few have and this is where we need to get some really skilled technicians who can dig in the weeds and help translate into action for the rest of us!!

I know that is a bit rambling but I'd be interested if there are any harrumphs out there.

Thanks!
