That is quite a claim. What have you done to verify the accuracy of your unit? Have you built a gas bench to verify response time and accurate reporting of the AFR? What certified test equipment do you have? What test procedures have you used to verify the claims you are making? 
 
Have you had your WB unit independently verified by certified engineers?
 
What type of environmental testing has been done on your units? Are all of the components used in your product been qualified for automotive use? Are the circuit boards conformal coated? What is the temperature range of the components used?
 
Or is it just another 'hobby' product you as so famous for?
 
Thanks for your time,
 
Al.

Wayne,

As much as I hate plugging our own product, as you are a fellow Aussi, 
I'll simply mention we do a DIY controller for the LSU sensor (in fact 
two DIY controllers, one with an inbuilt display). Our design is 
fairly mature and we have sold thousands as DIY kits. We also sell 
them pre-built. We also offer a fix-it service if you have trouble 
getting your unit to go (they are out of necessity complex pieces of 
equipment if they are to perform well).

As other will mention, there are a few people now who make low cost 
controllers for wideband sensors. Many are junk, and a few are 
reasonably good. We believe our DIY unit, when built, tested and 
calibrated as we describe, are as good as the Motec and Autronic units 
you'll pay up to AU$2,000 for. I'd say our unit is better, but that 
would be a bit OTT.
