So I need four holes to do tune with the wide band kit?

 

tune with your widebands then plug your narrowbands back in and be on your way. The ECM will compensate for the closed loop areas (narrowband)

 

Thank you. Thats what I thought.

 

The wideband O2's only work in Autotune Pro mode. You will need to take them out and reinstall your original 18 mm narrow bands if you want to have closed loop capability. It will run just fine without the factory O2's. The Power Commander V doesn't run any O2's. I think the 07 needs a jumper plug installed in the plug where you unplug the factory O2's. I would call Fuel Moto if you bought it from them or Dynajet one for information on this. Personally I would try and run the stock O2's. It will do autotune basic with the stock O2's.
