[QUOTE=911st;5540427]Just a note, if 5 cylinders were at 11.5 AFR and one at 13.5 AFR a single O2 would probably indicate a safe 11.8 AFR.

That's why you would still need to read the spark plugs. Then you can detect the lean cylinder. Plug reading is a must for tuning any engine, wide band or not.
