I can appreciate your reluctance to respond about the nitty gritty details of
how these devices are to be used.  I am eagerly waiting to find out what your
product will be.  For now we'll hook our sensors up to the NTK box at work so we
don't fry them.

We were using the wide ratio O2 sensor yesterday on a vehicle with a
programmable FI computer.  The car was on one of our chassis dynamometers.  I
set up the dyno controller software to hold the dyno at steady speeds for the
testing.  The throttle setting could be varied and the dyno would hold the speed
constant.  The air-fuel-ratio was read off the NTK system and adjustments to the
fuel injection computer were made to get desired AFR.  It really worked well. 
You could see the AFR reading quickly respond as the FI settings were changed. 
Handy tools to have.
