I have been Toying with the idea of somehow linking a PWM controlling HHO production with the throttle position sensor so that as I accelerate more HHO is produced. This seems like the next step in HHO designs, since as things are now, the HHO is either on or off and takes no account of driving conditions.

As you can see the pollution benefits drop off at higher rpms, and I assume the MPG gains do too.
The trick with be to somehow have your EFIE be adjusted accordingly at the same time.
any thoughts?
