You are way in over your head, you need to understand how the ECU works. There are two different types of 'modes' the ECU will be in at all times, Open loop and Closed loop. In Open loop, the ECU relies on the o2 sensor for input so it knows how much fuel to add. Open loop is anything that is not WOT. In closed loop(WOT, anyhting over 75-80% throttle), the ECU switches to Closed loop. In closed loop, the ECU relys on a predefined set of fuel maps to know when to add fuel at each RPM. The only problem with this is when you start modding and inducing more air, these predefined maps need more fuel to be added. Thats where piggyback fuel systems come into play(SAFC, eManage, ect) or full standalones. The piggybacks modify the a/f signal to the ECU and 'trick' it to add more or less fuel.

I dont understand what you are trying to do with hydrogen. Taken from another forum:

Not trying to be an ass, but you got open and closed loop switched around.

as far as this fix is concerned, do you take ONE anti fouler, drill it out and screw your 02 into it or do you take one, drill it out, screw ANOTHER anti-fouler into it and THEN screw your 02 in?

drill out one so the sensor fits in it. screw the sensor+fouler into the second undrilled fouler, and screw all three into the 02 bung.

If something blows up, at least it'll be in Broward County and not near either of us.

honestly it is not a waste of breath, i heard everyones point of view, i just wanted to try something that worked in theroy to me. Well the theroy didnt really work how i wanted it too... so I am going to re do it. Should I of listened to you guys, yes. But I am hardheaded. I speak my mind and like to try things my way, but when they fail i'll admit it... But sometimes I figure out some cool shit... I mean think about it... all innovation faces negativity... know what i mean... So after I do my plugs and wires (damn intake manifold)
I am going to tackle my head lights... I dont have trouble seeing but it isnt anywhere near where it could be at when done right...
