Kelly,the XLS files simply showed the O2 voltage curve vs Exhaust Temp and
Air Fuel Ratio, soare  not really   required to build the circuit.  I would
suggest contacting Ken Kelly directly and let him know you are interested in
the PC board that he intends to offer.  Might ask him for a copy of the XLS
file if you want one.

Contact Ken Kelly at ken7382@hotmail.com
