First the downstream O2 sensor you are speaking of will not affect your air/fuel mixture. Best 2 options is getting the code turned off with HPT, or doing a manual O2 sim. You caqn find more info on the manual O2 sim in the performance section if you search. You still need the second O2 sensor, and it spaces it out from the exhaust stream so it does not get the full reading.

If you don't have hpt you can find someone with hpt..

Using a cheater sensor really doesn't do you any good. If your going to go the route of using a sensor, save some bucks and plumb your line with a bung for your existing sensor.
