EFILive has the LS1b has the B3647 Commanded Fuel/RPM,which when set to 14.63, will cause the ECU to go into a semi-closed loop state using the O2 sensors to keep idle and part throttle AFR @ 14.63.

If I want my idle and part throttle set to 14.1, then my O2 sensors will be ignored. How does the ECU command the AFR when in this state since the O2s are ignored? By the VE table?

Question: Is there a way to set B3647 to something like 14.1 and still have the O2 sensors ACTIVE?
