Going to necro this tread just to give a few updates. As many of us know, not only was there a few things mentioned on the first page to try out, but BM3 also released a DTC Code Deactivation section as well. Unfortunately, here are my results:

All available monitors eventually went green
But i saw a pending P0420 code using OBDLink
Stock Map - Setting Decat Charge min to 0, Max to 199
