The only thing the rear o2 does is read the cat. If there is no cat, the purpose of having the rear o2 no longer exist. Get a plug in spoof or have the codes removed from the PCM

Its more than that, its in the tune. If you do that you'll be running a 10.5:1 AFR all day long.

00 and older rear O2 doesn't do that.

It's not in the tune, it has no affect on closed loop operation. Where it causes problems is in the later year cars that command open loop in order to test that the rear o2 is functioning properly.
