I'm sure someone who actually knows more about the MIL eliminators can give a better answer than this, but the main concern from the computers point of view is if the second o2 sensor is moving or not. The front one should be moving quite a bit, the second one should be barely moving, as long as the MIL eliminators keep the second (downstream) sensor fairly idle and stable, all should be good. Anyone who has better info on how the MIL eliminators work is welcome to correct me if I'm wrong, just recalling what I learned in my auto classes a couple years back.
