Found information online, and in the definition file so I figured I'd try it out.
I made the changes in the bin, and desired AFR dash display follows the table values.

However WBO2 is still showing the AFR ~14.7 with only momentary swings towards the desired AFR.
BLM numbers are only a couple digits higher as well (vs. without the bin changes).

Not sure what else to try to get it working?

I'm running the 7427 $OE BLHH bin on an AMC 360.
I'm also using the simulated NB output from the WB to NB PCM input if that matters.

VE is tuned pretty good (I think), last log averages looked pretty good to me.
