DIY_WB on Electromotive

Hello all, (reposting since the original didn't make it last night)

I purchased 2 diy_wb boards with the intention of building one for
general use, and the other to go into my old Vette with and
Electromotive TECII running their new wintec2 software.

The wintec2 software has a table in which you can calibrate the O2
sensor's output voltage to represent a particular AFR - was wondering if
anyone more experienced than myself could see any problems with my
reasoning on using the DIY_WB to control my AFR in this car with the
Electromotive ECU.

The only problem I can foresee right now is the DIY_WB output voltage
drops as the mixture becomes more rich, the Wintec2 software doesn't
seem to be written to handle this, I may have to ask for some help in
building a circuit that inverts the voltage output of the WB sensor....

Thanks
Gabe
