Should the O2 sensor be connected on a Power Commander V?
I just picked up a 2009 Road King Classic. It came with Bub pipes and DynoJet Power Commander V. This was installed by a Harley shop. While cleaning the bike I noticed the O2 sensor wasn't hooked up. The lead from the tuner has been jumped with a wire. Is this normal? What would happened if I connected it?

That is the same set-up I have with PC3 on my '07 Ultra.
Didn't the shop or PO give you the instructions?
What you have is exactly what I have on my bike.
I've put thousands of miles on my bike since my 2008 install.
Should be OK.
You are now running what is called an open-loop.
You were running a closed-loop.

Agreed...have had my PC-V on a 2010 and 2012, O2 sensors get disconnected. Was verified by the tuner who created the custom map.

What you have is a "Stage 1" using a canned map I'm pretty sure.
The o2 sensors get plugged in only if you are using the dynojet auto tuner http://www.ebay.com/itm/Dynojet-Powe...956b86&vxp=mtr
which works in conjunction with the PC-V.
Otherwise, no.

Is OK to use the O2 Optimizer even if you don't have a PC Commander?
My bike came with the V&H pipes and the heavy breather air filter. All this installed by the previous owner. I found the optimizer (2) from an old PC Commander unit that was in my previous bike ('07 VROD) and put them in my current bike ('08 Softail Rocker). I am planning to eventually get a PCV.
