I use WBO2 data from open loop AE and PE when the computer locks the BLM's to 128. CL WBO2 data will validate the corrections to the VE tables for rich or lean BLM's. A VE table causing rich or lean BLM's will also cause rich or lean WBO2 data in CL. BLM corrections have a limited ability to correct for rich or lean conditions. I've tuned several vehicles with AFR's. The WBO2 tuned vehicles run better, have fewer emissions, and achieve better MPG using CL WBO2 data.
