I did see one floating around, but don't remember where I saw it. You might find it here: http://www.thirdgen.org/forums/diy-prom ... -book.html
O2 cross probably refers to O2 cross count, which is the number of times the O2 signal has crossed the rich-to-lean or lean-to-rich threshold. Narrow-ban O2s should cross this boundary consistently and repeatedly when the mixture is at stoich. In other words, at 14.7:1 mixture, you should see the counts increasing rather quickly.
Terms and definitions can vary between definition and vehicle make and model.
