Hey all,

Does anyone know which box I need to disable to clear my catalyst error code. After installation of my downpipe I have a continuous error code reading "Catalyst System Efficiency" error and I believe it is due to my catless downpipe. Can someone please advise me what I need to disable on my ktuner software map to prevent this error from popping up again? I think it is P0420 catalyst efficiency but just wanted to make sure. Thanks.

We cannot assist you with disabling emissions equipment, but there are several test options available in the aptly named section under Main Parameters.

Yea, that is the correct thing to check off and you should be good.
