I found that O2 extenders don't work, and I have been having problems when hooked to the manifold of the engine drawing in water when hooked there. You may be fine though, just keep an eye out. I installed a EFIE, that's when my mileage picked up. On my Jeep, the O2 sensor compensated for the increased oxygen due to the cleaner burn of hydrogen. I have not messed with the IAT, or MAP sensors. Just the O2. There are 2 on mine, before and after the CAT(catalytic converter). The only one you have to deal with, on my model is the one before the CAT. The one after is for monitoring the CAT, it doesn't do anything for the fuel ratio.
My EFIE is from fuel savers, it is the single deluxe model. It is nicely packaged with test ports, on/off switch, adjusting pot, and a light to let you know it is on.
I hope I have helped, all this information is just what I have found is working for me. I am not a rocket scientist, but then again not dummy.
