I hope you are talking just about the O2s downstream of the cats. You do not want to disable the ones upstream of the cats. My downstream O2s were disabled as part of my tune. Those O2 sims would probably work as well, but I don't know.

When the car was tuned the tuner should have tuned out the rear sensors and left the front ones turned on. You can then plug the rear fittings. If you are getting codes the tuner should look into your problem. Properly tuned, you shouldn't get codes with only the two front sensors activated. The rears being tuned out will not affect your car's emission testing.
