I have an Saturn 2005 V6 engine. This engine has 4 O2 sensors 2 per 3 cyl. One O2 sensor from one set is wide band sensor but the other one is narrow band. How should I make the O2 diagram for the wide band sensor? How do I know how to tune these two O2 sensors boards to work for my O2 machine. The O2 machine is HHO booster. The schematics I was looking at are from Patrick J Kelly "A practical guide to 'free energy' deivces".
