I was told to turn off three things:
1. Cat efficiency codes
2. Cat over-temp protection
3. Rear O2 codes
I think what you have to do is find the codes in HPT, and you can check different boxes for SES light / store code / do nothing, etc. I don't remember where they are, but it's somewhere in the DTC section.

HPT>Edit>Engine Diagnostics>DTC
just check "3-No error Reported" on anything that has "sensor 2" in the description.
