A friend of mine purchased an O2 sensor resistor that he added to his car and he swears he gets better gas mileage with the resistor
Measure the value of his resistor. Get a resistor of the same value for a penny and try it yourself. I think it must be a pretty high value resistor to make a difference, because the input resistance of the ECU must be very high. Now if you are talking about injecting a voltage into the O2 sensor wire, that is something else.
