Will the PLX M-300 Wideband O2 Sensor Kit be compatible with a '91 SS ECU to use in place of our narrow band?

The above site describes the issue. Below describes the unit.

I would add it in addition, John...that's how I run mine, as my ECU seems to much prefer the output of the narrowband sensor, and then I use the wideband for tuning purposes and turn it off when not in use.
