adding a resistor to the o2 input wire

[guest001]

I've seen many threads and post on adding a resistor to the IAT input wire, or whatever, or IAT mods, but that doesn't make any sense to me. Isn't the o2 sensor then end all, final adjustment to the fuel. which makes sense cause why the hell is it even there.

I can't take the entire credit for this, but it sounds like it would work. I have an older one wire o2 sensor on my car so that's what I'll be talking about. but if I were to add a resistor to that wire, which size is the question, it would lower the voltage to the ecu and it would lean out the mixture.

I actually have a wbo2 sensor, so I could throw a random resistor in there and get a good idea of how lean it is and vary the resistor accordingly.

It makes way more sense then attempting to adjust the fuel maps, because when the o2 is work its uniform and steady, or consistant as hell, way better then any attempt to lean out the fuel maps so far.
