IAC could be acting up because it never budges! Also, CDiag5[6] is set, so that confirms some issue. Be sure the connector is plugged in and that there are no shorts.
The Fuel map Load/RPM axis don't have the extra granularity I would expect of a BUE2D ECM. Technically, it should probably run with the current maps (because the axis matches the actual mapping), but I don't recall seeing a BUE2D with that axis layout. Same for the Timing Table RPM axis.
Load is funky on occasion, but I can mostly correlate it to when I think you are hitting the starter button to keep the engine running, or when the engine is barely running.
