I advise every owner of any (not just FP7) Sunset Model locomotive with a QSI Titan DCC decoder to upgrade their models using a QSI programmer to the new sound files. For now, Sunset Models will continue to put the older Q2 files in their locomotives. They will let you borrow a QSI programmer if you ask them. It does take a little bit of time to set up the software and read the manual to know how to use the software, but once you know how to use it, you can easily customize your locomotive and improve the sound quality.
Click on the video below to hear the difference. Yes the video is shaky, too close up, (plus many more problems, etc), but the point of this video is hearing the locomotive. I'll do better videos of QSI Q3 files in the future as I find time to install Titan decoders in my models.
