Wideband O2 sensor question
Does anyone know if I can drop a wideband O2 sensor in place of the stock O2 sensor without problems? I would love to get accurate readings in my UTEC logs rather than just rich (below about 12.6) or lean (above about 22).

It is possible, you just need to modify the WBO2 so it produces an output signal for the stock computer to read.

No, you can't replace the WRX's front A/F sensor with a different type. The UTEC needs the stock ECU and the stock ECU needs the stock front A/F sensor.
