If you're splitting water into H, H, and O, and you're heating it sufficiently to cause chemical combustion and recomposition, the end result (if not harmful emissions) should be WATER. It came from water, it should return as water. There should never be an excess of O2 in the exhaust stream, unless you've introduced more O2 than H2. It just doesn't jive.

Since I don't believe that part, I don't well believe that you need to spoof the O2 sensor, either. If anything, spoofing the O2 sensor into running the car lean is the sole reason for the increase in mileage.

Without seeing a dynamometer tested emissions sheet, I'd never for a second believe that there was excess O2 in the exhaust. Not for a single solitary second. It's BS until proven otherwise.
Ay, there's the rub.

I pretty much agree with atfab's statement, but I also agree that there's no way I can prove that the 02 spoofer doesn't account for *all* of the MPG improvement (in a non-diesel), just as you are stating. I don't have the smarts to do it. You can make the argument that the scammers sell you the 02 spoofer for cheap in order to sell you the hydrogen generator for the big bucks.

But I also think there's two ways to look at this. There are tons of scammers, but there are also a lot of DIY kits and forums devoted to this stuff. You can make your own for under $50 and then smack your head against the walls of physics all day long. You aren't required to give any money to the scammer in order to "roll your own".

I do think there's a kernel of truth in all this. It works in the lab, but no one can get it to work reliably for all drivetrains in the real world.
