And the MAP/MAF is more important? I think not.

The ECU will see the MAP and the O2 sensor do not agree with the expected O2 in the exhaust. It will then go to the preprogramed lookup tables and go richer because there is more O2 than the MAP indicates.

Now just before you jump up and say differently, I use a scanner that allows me to monitor several sensors at once. I can assure you that with low levels of HHO (less than 1L/min) this is exactly what happens on my OBD ll S-10.

So what is your reason for more oxygen being in your exhaust stream when there are only enough H2 and O2 molecules to recombine into water?

I'm only a chemist in theory, so that's more a question than anything, but I doubt I'll get a satisfiable answer. I never do.
