Hmm, well, no-one really picked this one up and ran with it.  So.... I took
a walk across to the library and Lo! Seek and you shall be rewarded etc.
etc.  

If you check out 
http://www.bracken.co.uk/misc/
you will see a figure relating % O2, CO, H2, NOx etc to Lambda.  It helps
to explain why the outputs from lambda (O2) sensors are non-linear and also
partially explains the differing curves that Garfield was reporting either
side of equivalence.

Sorry if this was common knowledge already.
