This is an 16500 engine I wanted to convert to DCC sound for a while now; to go with the Lima RIO units.
The decoder is from Miniature Passion:
I programmed the decoder on my test bench:
I then brought the engine onto the layout to register it on the ECoS through RailCom, but somehow it didn't pick it up as a DCC decoder, but rather a M4. I have no idea why!!
