Wide band O2

Hi, I’m about to weld in a fitting for a second O2 sensor. Where’s the best place to put it?

Greetings.
This discussion explains where it is best to install it.
Can you share what model of afr gauge are you installing?

This, for testing only. I’m not thinking a permanent installation.

Thank you
