i use PLX devices. they have great wideband controller setups with excellent gauge combinations as well.

many people run this setup ad they run the linear 0-5 volt wire to their wideband controller/gauge as well as to their standalone EMS for data logging.

others just run the 0-5 volt wire to their wideband controller for the AFR reading and then run the 0-1 volt wire to their ecu to interpret stock 02 readings.

or you could have a additional bung welded on to your exhaust pipe preferebly 18 inches down stream from your head or turbo if your turbo charged and then run the wideband additionally leaving their stock o2 alone.
Reps for you, that's exactly what I wanted to know about the controller setup. I think I'm going to pick up the Zeitronix ZT-2 setup rather than just piecing it together
