Does anyone have or know where I can find an equation or chart of some sort that converts readings from a standard 0-1 Volt O2 sensor to air fuel or lamda values? I have been looking all over the place and every chart I run across is so vague it's useless.

 

This page (http://www.techedge.com.au/vehicle/wbo2/wbntk.htm) has a general graph, and I think there are others on this site. The stock-style narrow band sensors are worthless for tuning. A minor ground issue is enough to make the reading totally meaningless.

I would also suggest you check:

http://Rx7turbo.com/afhighlight.htm

It shows voltage readouts that work with the 0 to 1 volt air/fuel meter.

Good luck
