I've been doing research trying to find a way to either remap my fuel system or to fool my ecu into thinking that I'm way rich. I'll probably end up fooling my ecu by sending a bogus voltage to it. Probably by manipulating the actual signal sent by the o2 sensor.

I'm trying to figure out what the most lean mixture my computer can even interpret. If it can only deal with voltages that are telling it 16:1 or something, I don't think I'll be able to use this car.

Does anyone know how to check if you've got a wide band o2 sensor? I've got a 2001 altima, and I've been assuming that it's typical narrow band, but maybe it's not.

I'm going to be installing an EGT gage and an A/F gage as well in the near future so I can monitor what is happening if I'm able to manually manipulate the o2 sensor's signal.

I've been doing affiliate marketing for awhile and have a couple of sites that sell these HHO units. I don't sell things I don't believe in, so I did quite a bit of research on them and have really been completely sold on the idea.

It's important to keep in mind that you aren't really looking to use the HHO as a suplemental fuel - though a lot of sites will talk like it is really fueling your car. The small electrolysers that you see most sites promoting are probably only capable of creating 500mL a minute of HHO, which obviously is nowhere near enough to run your car.

The best place to really get a great idea of what you can do, how they install and what mileage you'll get from them is on youtube.

I've started up a new site to track that and a few other alternative fuels and put up a few vids from youtube where a guy goes into quite a bit of detail on how many plates to use, what the threshold of voltage per plate you need to have to generate good HHO production is, etc... The videos are 41, 42 and 43 out of what so far is 84 videos he has done on his HHO adventure.

I also think that Snax really got it bang on, the HHO causes a more complete burn of the fuel and delivers more power by causing that burn to be faster. The speed of the burn is a very large part of your engine's performance as gas that combusts after the piston has already begun its downstroke is nearly wasted.

The Oxy sensor is something that concerns me as well. One of the things that I think is possible is that a better burn causes more of the O2 pulled in from the atmosphere to burn as well in the combustion process with the gasoline vapor. In theory this should cause a lower O2 in the exhaust manifold than normal, which would cause the computer to lean the engine out a bit more to compensate. The O2 sensor is really there to mainly look for too much O2 and richen the mix to get a better burn as too much O2 will burn out the catalytic convertor.

Does that make any sense, or am I way off base on that?
