Default Needs an ECU and a new calibration? WUT?

I saw this article saying the 06 has issues with ecu and afr sensors causing it to sometimes run excessively rich. I believe my car could use this because it has many codes that don't make sense to me however it runs allright and I happen to have all of the MIL codes listed there and then some. I checked with tecstream and my calibrations are the ones the article says I need updated ecu hardware, calibration, and afr + o2 sensors. LOL WUT.

It says I need updated ecu hardware and updated afr (+o2s) and then a recalibration cuz my ecu calibrations happen to be the first ones and they are causing a bunch of codes and check vsc to turn on.

Sounds like a trip to the dealer is in order. Is there an open TSB or SSC open on the ECU?

Can you please elaborate? I don't know what's a tsb or SSC. And how would I check? I'm thinking of just sending it to Sia electronics to have it hooked up and tested for 100% functionality and soldered if necessary + have latest calibration loaded, and then upgrade my afr sensors to the latest design.
