Sounds pretty nice! I don't doubt that price! :-) I was just wondering
how you were doing it since you seemed to be able to read it pretty
accurately. I've been playing a bit with my EASE scan tool. It
doesn't give me the fuel/air ratio, but it will tell me the voltages
coming back from the O2 sensors, and I can probably use that to extrapolate
it.
