Hi-flo cat and the disabled second 02 sensor

Post by nYdGeo »

Searched but have not found this question being asked so here I am. After installing the hi-flo cat RV6 DP, when I created the new tune for it, I observed that by default, it disabled the secondary 02 sensor. The DP has the fitting for the secondary (post-cat) 02 sensor and it is installed and connected. Should that secondary 02 sensor be disabled? It is now and the car drives fine. I have no problem leaving it as is if the secondary serves no purpose, or if it's problematic to have it enabled. Just curious.

Thank you for your time and assistance!

You can try enabling it and see if you get any errors.
