I'm looking over the innovate LC-1 manual and I have a question.

To use a wide band 02 sensor, do i have to go to an exhaust shop and have an extra 02 bung welded in? This seems highly inconvenient.

Or am I just misunderstanding the hookup? Do I remove an existing 02 sensor in the exhaust, somehow close it off, and screw in the lc-1 O2?
