I really dont do anything special. If for example you delete the rear oxygen sensors on your vehicle just set everything for bank 1 or 2 sensor 2 to not reported, and no mil. But before you do this remember to check all laws to make sure you are not violating anything. It will be completely up to you if you decided to disable something that is illegal.

Or in my case do the carpet bombing approach and set everything with O2 in it to not reported. Did the trick even though I was running perfectly functioning upstream O2 sensors. Go figure.
Got everything except for evap to report ok which is good enough here in Ontario.
Well that's easy thanks for replying guys, I was wondering why it would even be a issue since they could be turned off in the software anyways but I never paid attention to to the readiness test so I was curious.
