MyLocoSound Firmware Update
Return your sound board to us for reprogramming with the latest sound files. Send the board only, no remotes or IR cables needed. You can also change from Diesel to Steam or vice versa. Just specify below which file you need. We can only update the newer Universal Sound Cards (Green, Blue, or Black). Not the oldest Green boards with pots. See photos.
