Thread: Wideband behavior

Probably not normal. 15.1 is common, but 13.9 is pretty rich. Maybe your narrowband o2 is bad since your trims are at zero.

Did a quick data log, narrowband seems to be responding like it should.

Made a quiick little video.

This is what I thought when I first read this.... I have tuned a few cars with WB and it most of the time stays north of 14.5 when cruising. And both your STFTs and your LTFTs should not lock at 0.0 while cruising around.
