Edit: dschultz confirmed the UEGO piggyback in model 30-0333 won't work out-of-the-box, but with the protocol data from AEM the plugin may be able to be updated so that it will.
See
this thread if interested.
In the meantime I hooked up the rs-232 lead using a custom db9 connector harness and a serial>usb cable. 9600 baud though... would be really nice to get fast polling via the ECU but I haven't/will not do the TGV delete and not interested in removing the rear O2 sensor/config from my e-tune.
Hopefully the OBD2 method will get a spark of life...
