Recently picked up a Davis Carchip EX.
One of the data parameters I can trap is O2 Sensor output.
Is there a way to convert that to A/F ratio?
I'm assuming the stock unit isn't wide band.
Any help or info would be appreciated.

Found this really informative link on Bosch wideband sensors

I suppose that I'm partially responsible for this post as I led obe to believe this is possible. I was too busy at the time to find the thread, but this is the one that leads me to believe there's some kind of relationship:

Here's one more by our guru, Andy:

I too have the CarChip E/X and would like to hear if we can get A/F data from this information. And if it's only part of equation, what other bit of data might we need?
