Hi,
        
 I read a lot of discussion but I have not yet understood some things.
        
 I purchased a used XT660Z with a PowerCommander V.
        
 I bought O2 Optimizer from OFF-THE-ROAD:

         Now, I do not know if I have to remap the PCV to set at 0 values in the stock closed loop area (from 2500 to 7000 rpm and from 2 to 40% throttle).
        
 Can anyone guide me step by step installation of O2 Optimizer?
         
        
 Thank you!!
         
        
 PS sorry for my english
