I think you mean using one EFIE gizmo to return information to the ECU/PCM. If yes, then based on my observation of the data, I tend to disagree. When I datalog a stock 02 sensor configuration, I can *see* that the second 02 sensor is reporting different oxygen levels after the cat. This makes sense (to me) because there has been a chemical reaction in the cat that has consumed some of the oxygen (right?!?!?!). I know that the oxygen atoms are still there, but I think that when they are combined to make different (non-harmful emission?) molecules, the 02 sensor doesn't see it. Hrrrrmmmm, maybe that's why they call it an 02 sensor, because it only "sees" the 02 molecule. That never occurred to me.
Does this make sense? Can someone chime in to lay down the skinny?
