Re: Wideband Question
You NEED a wideband controller...thats the point of the wideband. In a stock configuration, the controller is obviously internal to the ECU...
I am going to guess that as long as its 5 wire that sensor is a WB.
As far as a pinout, look on the plug to figure out the manufacturer and go from there.
Most likely a Bosch LSU4 or one of the NTK units (L1h1, L2h2)

This would simply require a WB O2 sensor and a multimeter, no need for WB controllers and such... (A/F Ratio being 2*Voltage +10)
This could be a nice alternative for home tuning? (don't know if this has already been discussed)
