Free MyLocoSound Firmware Update
Return your existing sound board to us for FREE reprogramming with the latest sound files. Send the board only, no remotes or IR cables needed. You only pay for return S/H. Contact us via e-mail.
You can also change from Diesel to Steam, etc. Just specify below which file you need. We can only update the newer Universal Sound Cards (Black, Blue, or Green). Not the oldest Green boards with pots. See photos.
Note: Many of the revisions fix small bugs that you may not even be aware of. But there are also some that may vastly improve the quality of your sound.
Note: New orders are always shipped with the latest firmware.
