Wideband O2 sensor placement

[Templer]

As so the inside right thigh on my leg doesn't COMPLETLY bake. I am installing a separate wideband O2 sensor to EACH exhaust pipe FOR TUNING!!!! Have a newer Pro Pipe (mfr in 13) and older (nla) pipe. Older is for 06-07 Dyna's.Where would you locate the new sensors. Separate system with no connection to the factory ECM or narrow body sensor. These will be for tuning with a lap top and data logging. SERT is in use. H E L P!! Duel A/F gauge to be installed to panel in 1/4 fairing.

There was a thread where someone posted a Bosch O2 document outlining placement...
But a wideband should be within 6" from the valve.  Yes, people place them in places much farther than that but it will change the A/F values they display (leaner).

I have mine 2" from exhaust port.

Don't put them on the inside radius.

Don't put them on the inside radius.

True that. Probably the worst of all places. Looks good cosmetically but works like crap.
