OL SD = Open Loop Speed Density.
Speed Density is NO MAF, just the VE Tables
You're running CL Closed Loop as you are using the CL feedback from the narrow bands.

IF You are running MAF, I think the VE Tables aren't used & you need to play with the MAF Tables


The integrator hovers around Stoich. PCM counts Cross counts of the Narrowbands going rich & lean.

If it's rich & the INT has moved down by around 5 counts The BLM lowers reducing fueling & the INT tries again.
With the BLM pulling fuel (8-10%) the integrator is hovering around stoich again so is happy.
