If I buy an exhaust that has the o2 bungs and want to run the pc111 instead of the sert, is there a setting to keep and use the o2 sensors and the closed loop? I see all these posts that the pc111 bypasses 02 sensors so you can run other exhausts without the o2 sensor bungs. I want to run the v&H with the pc111 over the sert for tunability purposes, without losing the o2 sensors and closed loop. hope I made sense to someone!!!! Thanks

 

It seems to me like the big selling point for the PCIII is the O2 sensor bypass. If you're of the mindset that the O2 sensors are a good thing, you'll probably be happier with the SERT. The PC maps all count on the O2 eliminators being installed.
