Wideband o2 conversion?

Hey all!
I've been dailying my golf for a good few years now and thinking of having a few running kinks smoothed / tuned out properly, it's a 20v motor running a qpeng wiring setup and tune on a MBE ecu. Basically has anyone converted their mbe992 narrow band o2 setup to wideband? And is this primitive ECU even capable of this? If this can be done does anyone have the qpeng pinout or even the instructions for the ECU? I must have bought this ECU setup 10 years or so ago and can no longer find any of my paperwork on it.
Thanks in advance guys and girls!
