Hi UFO
thanks very much for thoughts, I don't want to refute that at all.
I have already an HHO dry cell system installed. I am just about to change the PWM and EFIE controller. With the new PWM/EFIE I should get better fuel economy results.
With the old system, fuel economy about 3 %.
with the new system, I am sure to get more.
But with a HHO system the fuel economy is limited, that's why I want to try to vaporise the fuel first.
