I just loaded the SCT LiveUpdate software in the laptop and made my first run through the neighborhood logging the data. Man, this is cool.

Anybody know how to calculate the a/f ratio from any of the o2 sensor outputs, or some other data point?

Sweet decision getting the SCT XCal 2!! But this question is probably best answered over at the SCT Forums......

Thanks! I did post over at SCT, just trying to cover all the bases. The response there was that you can't tell the actual a/f without a wideband sensor, but you can look at the fuel trims and the commanded a/f ratio. It may or may not be what's actually happening, though.
