Yeah but what I think is being missed is that each oxygen sensor exhibits a highly nonlinear measuring nature, which is unique to each sensor brand. therefore, driving electronics are unique also, and modifications to adapt one circuit to another, based on the circuit operating linearly, are unsuitable.
