HI! There. I'm just newbye as you can see , glad to find new forum to glean some gems of knowledge from, and contribute. This is my present situation i 'm in the process of getting together an HHO cell. I have an 01 Subaru Forester,which has a Front stock 6 wire bosch wideband 02, which operates between 0-5 volts, also 1 rear 02 senser downstream of cat. I still have an efie from eagle research should i try this on my wideband 02??I , i know which wire is the a/f signal or will a proper size diode drop the current /volts aprox. 1v. do ? I know the diode is not varible unless someone knows if there is variable diode that would work?? I have some 02 extenders on the way but i don't think this will help much .Sorry for all ???

Hi Atechguy,

Welcome to the forum! Feel free to start a thread on this or find one that is already in the Renewable Energy section.

With the o2 extenders, do you mean the non-foulers? If so, they didn't work for me personally but that is just my experience on one car.
