Thanks for the suggestions!
I downloaded fresh ROM from the support site and made sure OFT was fully updated.
Modded ROM to set IAM to 1 and logs look good after a couple days. IAM logs at 1, and no knock correction or change in IAM.

Thanks again for the assist, steve99! Your posts have given me a a ton of info to get started with OFT tuning.
