OK count me as confused as well. I own a 6.2 Sierra with cats and a 17 Camaro SS with ARH catless longtubes. If you are truly going catless there is no need for sims at all. Turn all of the rear O2 codes off as "non-reporting" and no code will ever be set nor reported into the ECM. under each of those codes on the ECM side there are at least 5 or more options in regards to how many events the events needs before it triggers the MIL or to set them to dont report.

That is the best way and cheaper than buying sims that are really not needed since you are already paying for the tuning credits on the ECM side.

I'm disabling the factory REAR o2 sensors via simulators.  i have two trucks, one is under warrantee the other truck is not.  thus why i'm going with simulators right now.  wanteed truck will not be getting enriched.  but I wanted to install the full track exhaust on it
