i would like to know or where to find out if my 2008 civic 1.8 has wide band or narrow band sensors. I would like to know because i'm hooking a hydrogen generator to the car and i might have to manage my o2 sensors. most cars before 2004 have narrow band o2 sensors. Has anyone tried a hho generator on a 2008 civic?

 

wideband is wideband, tecnically there is no such thing as narrow band o2 sensors only switch type sensors factory ecu's use these, these are closed loop i recomend somthing like an aem uego or a haltec and then you are gonna need to take feul out with something like a apexi neo or stand alone fuel managment neo is like $340-360, stand alone very pricey

 

HHO is a scam

i don't know about you but i'm using about 4 ounes of water per 100 miles and i've gone from 35 mpg to 41and a half . sounds like thats worth what 4 ounces of water cost. i'm hoping for 50 miles per gallon but i will need a o2 enhancer.any one with a simple cheap solution? there are many for narrow band o2's and they are cheap. I will also ask the question again where can i find out if i have a wide band o2 sensor.
thanks

 

You can believe what you want to believe but the science doesn't back you up. If you don't change the mixture you are absolutely guaranteed to lose mileage not gain it. Any mileage increase experienced is from some other factor, like not stepping on the gas as hard as you used to.

In order to be able to run the engine way lean and be able to save gas that way you need from 100 to 1000 times as much hydrogen as those little cells produce. At that point you may just reach zero sum, enough to offset the huge amount of electricity (ultimately provided by the engine) required to produce the hydrogen.

If this stuff worked it would be quite mainstream. There is no conspiracy to stop it, the reason why it doesn't proliferate is that it doesn't work.

But so I don't look like part of the non-existant conspiracy I'd be glad to help you continue your research. The simplest way to lean the mixture way out would be to forget the O2 sensor and ECU, and just reduce the fuel rail pressure. You can get down a few psi by applying a full vacuum instead of manifold vacuum to the vacuum line on the regulator. Beyond that you will need to modify the regulator or replace it.

A more elegant solution would be one of those fully-tuneable aftermarket ECU's where you can dial in the fuel curve.

It may even be possible to forget the H2 generator entirely (which as is typically built, is so puny it is just for show anyway) and get some mileage gains from a fully stock car by leaning it out. The tradeoff would be lower performance and excessive NOx pollution.
