Why you might want to keep those amps down?
http://www.hydrogen-boost.com/September%202007.html

Info for diesels which might apply to gasoline engines:

" In the charts below notice that hydrogen production is not free. It takes energy to produce the hydrogen and this energy does not always get compensated for with improved combustion and efficiency. The key is to produce only the hydrogen you need to ignite the combustion mixture at the ultra lean mixture we produce with our electronic control circuit or the normal fuel mixture in a diesel engine. If excess hydrogen is produced the improved mileage will be lower than what is possible at optimum hydrogen production.

In the charts below the light blue shaded area represents the possible savings with Hydrogen Boost. The yellow shaded areas represent the possible NEGATIVE savings with Hydrogen Boost. Notice that at idle there is always a negative savings and at low cruise the savings may be negative or slightly positive. As stated in recent newsletter and documents the Hydrogen Boost benefits are especially prevalent when high power and torque are being produced (when lots of fuel is being combusted). This really shows that Hydrogen Boost can be most valuable with vehicles that are heavily loaded or underpowered.

The conditions where Hydrogen Boost may improve mileage the least is when the driver is already implementing driving tips like slow acceleration and cruising at low speeds and throttle settings. It may be possible that the cost of the hydrogen production could be higher than the benefits of that hydrogen to the miniscule amounts of fuel that are being combusted while using these efficient driving techniques. This is exaggerated when the operator sets his hydrogen production too high for the engine he is operating. "

Set this switch up to be activated by a wire(chain?) and spring connected to your throttle arm. Might need to extend the arm some. Adjust it so that it activates the relay operating your cell at a throttle position just under that required for cruise at 55 mph? This should increase generator efficiency.

Or use a PWM that changes frequency with throttle position....

Good info by the way....

I thought you didn't trust anyone out to make a buck? Make up your mind.

I do not necessarily discount what they have to say outright, but that chart indicates exactly what physics should dictate in this situation. That there is a point of diminishing returns and that more amps decreases efficiency. It is one thing to claim that "Our PWM will increase production by 35 %" or "Boost your mileage by 40-60%" with no real proof other than testimony from satisfied customers. But hey, this chart, based on information from Purdue University is pointing out the weaknesses in the system. Now I suppose that taking them at face value in that the data is from Purdue is a valid point. It is referenced by several web sites. It was a student led research project as well.

However, I work at a University and understand that if this were inaccurate, by now, Purdue would have sued these guys and had them remove it from the web site. Universities take this stuff very seriously.

I do not agree with the rest of the site or even his full analysis of the report. The vehicle only showed a 9.x% increase with HHO alone. The higher gain was with Biodiesel and HHO. All those values seem to be at acceptable levels and within what many home experimenters have seen.
