Thanks, Bill. Been looking for a diagram for using one of the wide-band
sensor. One nice thing about the wide-band O2 sensor is that the response
curve is much less radical than the typical O2 sensor which means you can
get a better feel for what the indications are telling you. The voltage
curve around 14.7 A/F ratio of typical O2 sensor is so steep that just a
little bit off makes a bit difference in the indication.
Only down side, is last time I checked the wide band O2 sensor were fairly
expensive compared to the older ones.

Here is a nice overview of Wide Band Oxygen Sensor (WBO2) electronics.

A pal used to sell the parts & circuit board kits, just as a service to
the
Do-It-Yourself Electronic Fuel Injection (DIY-EFI) list subscribers.
TechEdge ripped off the design and is selling the electronics at
substantial profit.
Here is a link to the DIY-EFI "non-profit" WBO2 kit site:
