GGG, I said he updated the firmware but that's just me playing loose with terminology. I suspect he reloaded the sound file as you say but I don't know. I ran the engine conventionally using a Lionel PH-180 and a MTH Z-controller. And I ran it with DCS also with the PH-180. In any case, seller accepted a return for refund so I've washed my hands of it.
