Big Brown's Automagic - The last episode in my DSM story.

The AEM widebands use the same old Bosch sensor, but they use a different connector with a resistor specific to each individual sensor to calibrate it. So they pretty much come pre calibrated from AEM versus you having to do a calibration yourself in the fresh air when you put in a new sensor. The NGK box is nice though because it is pretty much based on the AFM1000 unit and is easy to use higher quality wideband sensors than the cheap failure prone lead hating Bosch units.
