NOT SO; we have two of them here we've extensively tested. Our
'negative' comments were based on both looking at the design AND
checking out it's behavior against Horiba, NTK, and Bosch equipment, as
well as against a full-sweep gas calibration bench.

What does 'good' mean? Were both devices' sensors placed right next to
each other in two bungs running at the same time? Have a datalog then of
the results? :)

To these guys, apparently being off as much as 0.5AFR isn't 'any
significant difference', and 'good' accuracy.
