Xero-Xero,
did you test the mileage before you re-flashed the programing? IF so what was it then?
I have been looking all over and found info
here. I am working on a an 8 plate(7 cell) version myself. I will post more about it when I have it assembled and tested.
I have also joined another on-line forum dedicated to HHO generation for cars. Look
here. Over there I go by Mr Fixit. They are pretty informative, share information, and very civil so far. It reminds me of the infopop biodiesel forum. Over there I read that it is 'recommended' that you have 1/2 liter per minute per liter of engine size for best results. So I guess I'm looking for about 3 3/4 liters per minute for a 7.3.
I had hoped to find someone here who had done this and could point the direction, the other site seems to be predominately gassers.
