Cruising, about 14.7 to 14.0, idling/coasting at 20.1 to 19.8.
Are widebands more accurate, or is it better just seeing a wider range of AFR's?

Widebands are more accurate, have more range, and sample quicker than you can sample with a Scanguage II. By the way you should be idling closer to 15:1. I would also worry about how far below 12:1 I was going under WOT.
