DeCat-CEL solution

I'm one of the fortunate few that my P0420 doesn't go off often. In fact it hasn't this year ever since I changed to a different mid-pipe (bung relocated further down). But this seems to be a good long term solution.

Yes, Loki, you have hit on what I'm driving at. What is the failed O2 sending to the ECU to make it happy? If we know that it becomes a duplicatable solution.
Otherwise it's just a gamble that one can lay hands on a failed O2 sending something that will make your ECU happy.

can you try it with a good upstream O2 sensor? I think it is easier to find working condition ones than verified failed upstream sensors. This is an intriguing topic.
Gawd, we must've ran out of rx8 topics nowadays. Oh! Ice cubes!!!!!

I don't know if it requires a failed 02. The downstream sensor is different than the upstream. Try it with any up stream 02 sensor and see if it works. I have over 1000 miles and still no CEL....
