I'm going the reiterate my other post in here and say this, but first I'll add the disclaimer that I'm not an expert I've never tried it and I don't profess to be or have done either of those things.

The science behind HHO and the basic principles of the idea would suggest that it should work. However the problem is that cars are not as simple as people like to think they are. Think about it every car out there is designed to work no matter where you go with it which means they are designed to cope with a staggeringn amount of variables. High elevation, low elevation, extreme cold and heat, high humidity, low humidity, different octanes levels of gas, slight variances in the makeup of gas, different levels of ethanol in gas, the list goes on and on. All of those things will affect the the detonation of the fuel so your cars computer is designed to adjust for that and therein lies the problem with HHO. When you use HHO the cars ECU will automatically adjust to compensate for it usually by changing the timing or increasing the air in the air to fuel ratio.

Now to get the system to work you would need to have the computer reduce the amount of fuel used for combustion which means you want to reduce the amount of fuel in the air to fuel ratio BUT keep the same amount of air therefore using the HHO gas as a substitute for actual gasoline. However your car has no idea that you're using HHO so all it knows is that it needs to readjust the parameters to keep everything in order and that will negate any effect of the HHO which would then mean that you could actually decrease your fuel economy because you're running the HHO generator but not getting anything from it. The best case scenario is that you have no change at all in that case.

Now theoretically you could see gains if you were to tune your car to work with the HHO but I would be wary of that personally because I don't know how precise an HHO generator is. If it doesn't produce a consistant amount of HHO you would have to allow enough of a range to compensate for the varying levels of the HHO which would kind of bring us back to the original issue of having enough compensation to negate the effect entirely. The other problem with that route is that now you've sunk however much money into the HHO generator plus a tune which can run around $500 and all the work and time to set everything up and if you don't see any results or even worse have losses now you're up a creek without a paddle. You can't just pull the generator off because you're computer was tuned to work with that setup so then what?

I'm not saying it's impossible to see gains from HHO but you should expect a lot of work and time before you get anything be it good or bad. Plus with the amount of money it would cost you could do a ton of other mods that have been proven to work time and again vs one that is rarely shown to help.

Either way it's up to you and it won't make any difference in my life if you try it or not but if you ask peoples opinions on it you should expect to see ones that don't mirror your own thoughts on the matter. Basically just HYOH and YMMV (hike your own hike and your mileage may vary) is all I or anyone else can tell you. none of us are in charge of what you do or don't do. Hopefully this doesn't ruffle any feathers because I don't mean to be offensive but that's just the way I see it.
