OBD2 is in general working without issues. My TÜV guy didnt even notice that a other ECU is connected 😃  
Do u have proper termination on the CAN?..What is ur baudrate?..Are there other ECUs on the CAN?..is the CAN in general working or just the OBD2 stuff not?

obd is working now, i changed to 500k, but the rpm sampling rate / refresh rate is very slow. i have bosch bluetooth obd Esitronic… hope the dyno guys have faster systems, or other pickup method. thank you

Hello to derUltraTT, could you tell me everything you did so the EMU black could deliver a working OBD-signal? I am also in Germany and have an (old) EMU ECUMASTER (the silver one) in my car and would need an OBD-plug for the TÜV. Appreciate your info

regards

I know, that is why I would like to understand what needs to be done for the EMU BLACK (not classic) provide a working OBD to use for the exhaust test as part of the TÜV. I am considering replacing the old EMU with the black .

Just set the option for OBD CAN stream…nothing more.
