I have a O2 sensor code

[chrisldibiase]

I have a check engine light on for my rear O2 sensor since I have a catless mid pipe. The code is P0037 and im trying to see how I can turn off the code and even out the fuel/air ratio. I heard that when the O2 sensor fails it makes the car run rich and I can tell that it is due to the smell of fuel.

Rear sensor shouldn't give you much problems since it's not the main o2 sensor, however, in order to disable it, you'll have to be on the main page, see Tune Customizer, press Edit Settings, and go to the Disabling DTCs tab. In there, you'll just press the I have read and agree with what the text says, and then go to Advanced. Just search for whatever DTCs you get.

About the editing part, as soon as you'll install a new tune, it will advice you about local laws and all that stuff, just accept it, and once the tune is installed, you will no longer have the error.
