It's not that far out of line for, say, a car with the stock
commanded 11.7:1 AFR and some jacked fuel trims from
headers. +15 LTFTs would about do it. Looking at the
idle AFR on said wideband would be instructive though.

It should "flicker" because the engine bounces fuel
around in closed loop. If you turned up the smoothing
it ought to resemble 14.7 (if this is something you can
do in the handler interface program). But at least it's
bouncing on both sides of the right answer, so it's
alive and not completely ridiculous.
What does the scanner show you for WOT fuel trims
whilst getting this low AFR?
