Philip,
        You lucky guy your have "scored" a wide range NTK UEGO sensor (it's
worth about $950 Australian dollars (approx $700 US)). The only problem is
you need the controller to run it. The device can read from 10 - 20 AFR and
a similar unit (NTK say it is not the same but I have my doubts, I priced it
as a spare part about 3 years ago it was $250 US) is used on the VTEC-E
Honda Civic.
The controller is about $350 Aust ($220 US) and is a small box designed for
firewall mounting about the size of a cigarette packet and gives a nice 0 -
5 volt output. There is also an intelligent controller (ie. microcomputer
controlled) but it is mega dollars.
We all wonder how the factory guys map there cars so well don't we, well
they do it with this device !!!
It's sort of the holy grail in EFI at least it was 9 years ago when I first
discovered it. If you have a close look at some Formula 1 engine photo's
from the "Turbo era" have a look at the Honda exhaust pipes.
How times change, now it's on a production car.
"CS" is a joint venture between NGK and NTK in Japan. Who is NTK you ask ?
NTK is the ceramic (industrial) division of NGK spark plugs.
As I understand it Horiba have taken over the marketing in the USA (there
are some cross patents or something?) so if you give them a call they should
be able to help.
You could give NTK USA a try too as the situation may have changed.
Bosch have a similar product called the LSM11 (4 wire but still wide range).

        hope this helps,
