To add to this conversation, and I may be wrong here, but I'm pretty certain that the pc-v with auto tune module is the only option that gives you a real "closed loop" set up. Unless I misunderstand how the woolich and zeitronic auto tune modules function, I'm under the impression they don't actually create a live map that will adjust values for you.
My understanding of the other auto tune modules I've seen all require you to download the data and then submit changes to your map via a laptop or similar.
I've used pc-v with auto tune in the past and it will create its own map while you ride, and submit the changes automatically to the power commander for you. It is always on and will compensate for temperature and any mods you add along the way
In my experience the best option would be to have the ecu flashed to have o2 sensor, and PAIR valve turned off, open secondary throttle plates earlier and adjust timing all within the ecu, then make necessary changes in fueling to compensate and make it run proper. THEN you add the pc-v with auto tune to create your live map.
When you flash the ecu, the o2 sensor is turned off. So there's no live adjustments being made. The factory sensor is narrow band anyways so it wouldn't be accurate for making precise measurements like the wideband sensors are
