Ok here's the setup.

2007 Fatboy

Vance and Hines Big Radius

Screaming Eagle Intake

PC II USB EX

The PC instruction say to install O2 eliminators. What's that all about? I thought the computer used that input to adjust for variations in fuel, altitude and stuff like that.

Or is it that once it is dyno tuned you don't need that auto adjustmnent input anymore????

The o2 sensor eliminators are for the PC III to control the entire spectrum of the map. The stock sensors are only a narrow band and control the map for a very narrow section of rpm down low, after that they are useless. We have installed a PC III on a 07 RK with the o2 eliminators and it runs like a champ! :)

Does the O2 feedback actually gain or hurt performance, or is this strictly for the EPA?
