procede has a built in o2 sensor if you have the older harnass. If you have the newer procede harnass and the Rev3 then you have to wire it back to where o2 sims work. There is a thread on this. If you don't want the hassle of wiring it back and forth then yeah. O2 sims and canclear off is your solution
