I bought this DCC/sound-equipped Porter in November 2011. Which model of Tsunami decoder board is used in it?
Thx, Greg
The decoder is a SoundTraxx OEM Tsunami decoder (not to be confused with the Bachmann Sound Value made by SoundTraxx) with features set to Bachmann specifications.

The use the above as index to the following. These manuals are for the Tsunami decoder and mostly can be used with the OEM decoder made for Bachmann
