I just bought an 02 Emulator/Simulator from ZZP. From what the ZZP tech guys say you cant just use any o2 sim. It needs to have the correct resistor it in that our PCM likes so it will report back the right MV then letting the cat test to complete. I just got it so Ill pop it on and report back.
If you bothered to read this thread you would know that those do not work, your car will still dump fuel.
