Wondering if anybody else has gone down this route and how it turned out?

I tune these cars and I don't even use a wideband on my own car. Its "close enough". I have a P3 gauge but I just use it for oil / coolant temps. I have boost cut and closed loop fueling and i don't need to be staring at my AFR while I drive... I need to be looking at the road. =)

Not a tuner but in my experience this tends to not work out too well. Did exactly the Innovate setup on my old boosted RX-8 and my tuner flipped out on me
apparently the Innovate unit (older LSU 4.2 sensor/controller btw) has a slower polling rate than what is reported by the ECM...he had gaps in the data. Not only that but the position of the wideband put it in a slightly different position than he was used to and was not getting the adjustments he was expecting from over the air tuning.
I'm pretty sure if you can position the sensor to have better than OEM location (not sure if it's possible) and tuning on a dyno so they can directly measure changes on the fly it might work. Keep in mind tho that the OEM sensor is designed to not require service/calibrations throughout its life span. One thing I hated about my Innovate unit was that it required constant air cals to maintain accuracy
