It sounds like your vehicle doesn't report lambda through the standardized OBD-II PIDs.

Calculating lambda off of O2 voltage would be difficult at best. If you don't have a wideband O2 sensor, it would be near impossible since they are intended to sway between 0.2 and 0.8 (or similar numbers) numerous times a second.
