Narrow band doesn't disable

Megasquirt2 2.6 I'm tuning alpha n (Hillborns on a SBC). I have a single wire O2 sensor, but have it disabled on the EGO menu and have the "operate below kPa" set at zero. If I disable the narrow band on the EGO menu, it changes the tune (gets fat) the pulse width jumps 20% or more. Why is the O2 sensor affecting the tune if it's toggled off?

Could you post a data log of it running with O2 correction turned on and a copy of your MSQ?
