This is how the conversion graph looks like for CD700.

Hi Tom,
I'm thinking this polynomial fit would work pretty well for scaling to convert 02 sensor voltage (which is already available in NDSII) to an AFR reading. Not sure how difficult it would be to implement it but it would be awesome!
(x = volts where 0.364 < V < 1.858): AFR = (14.7) * (-0.0212*x^5+0.1281*x^4-0.1728*x^3+0.0432*x^2+0.1864*x+0.7323)
I attached the excel sheet I made to come up with this fit.

Thanks for the info. I'll look into it.

Awesome. I'm very interested in this being added.

Bump, any thoughts on adding support Tom?

Related but different from above.
Would it be simple to add support for AEM's wideband sensor? I bought the CANbus enabled version which supports CAN, serial and 5V output. The CAN doesn't integrate with my 03 Maxima, but I was hoping I could use the serial output to my laptop to log alongside the rest of the NDS 2 data.
