Hi guys. got a question. I own a 09 classic with some stuff done including a pc5 with auto tune but no O2 sensors but on the fuel moto site i see kits withO 2sensors included. I would think they would give better fuel control with them? also how does auto tune regulate fuel ratio like O2 sensors?

 

Are you certain the PCV has the Autotune? From what little I know it (the AT) would not operate at all without the new wideband sensors in place and connected.

Maybe it just has the PCV with a map loaded?

 

Auto-Tune has two wideband O2 sensors in the kit that must be in place for the system to work. If you don't have the O2 sensors the AT isn't working, that is if you have the AT modules attached. I suspect you have the basic PCV without AT.
