Anyone ???
as already said above by a few people you can relate an AFR to lambda (although there are different types of lambda using different calculations, try googling brettschneider and spindt)
but not to CO, as you can raise CO, with a corresponding decrease in CO2 but have the same lambda ( and therefore AFR)
hope that makes sense
my tech edge display has a jumper that can be set to give either AFR or lambda depending what's required, I prefer lambda now
