Sorry for the cryptic description but it’s all I have. The locomotive in question is my OMI Amtrak P40DC which is pictured in another thread I posted recently. The notes I received with the locomotive indicate that the install was done approximately 10 years ago with a NCE decoder for motor control and a Tsunami for sound which I guess was how it had to be done in O Scale back then. I have several recent Sunset diesels with QSI and love how the twice F6 for start-up and twice F9 x 3 for complete shut-down works. Can this be done with the older Tsunami?
