I a wondering if this engine has an older PS-2 that has to be upgraded, or is this year OK? I have tried 3 differ TIU's, and 4 different remotes, says same thing out of range and no file. Is it a case of reloading the sound file?, or is the board an old one and maybe I should just update with a PS-3? Any help or suggestions would be appreciated. This loco is an MTH one gauge 70-2037-1. Thank you, Bob.
