Lamda readings
Just finished hooking up the Zeitronix WBO2 data logger and there is a graph for Lamba but I haven't a clue what it means! I've conducted some searches but can't find any info. Any Info would be great.
On another subject how do I post pics. I feel like a poser and need to be verified.
Thanks,
Choray

The usefulness of using lambda is that it will work with any fuel, whereas if you use afr you have to calibrate your meter based on what the stoichiometric ratio of the fuel is. This is usually not a problem with us since most of us here in this forum stick with gasoline, and using afr instead of lambda is more convenient because of familiarity.
