GregR posted:By now I'm sure a lot of people have bought the SER2 and necessary cables to run Legacy engines in Legacy mode using the MTH premium app. Can anyone, even a single user, say that they have been able to get Legacy diesels to automatically ramp RPM's in response to throttle adjustments using the IPHONE version of the app? I just can't get RPM ramping to work unless I do so with manual adjustments. All other features like quilling horn work perfectly. Am I the only one with this issue?
From @Railsounds from a post in July... Rudy is Lionel's sound engineer and works with JonZ and is a resident of Dr. ZW's home for Legacy Users.
In Legacy mode, the locomotive only ramps RPM when it gets an absolute Legacy run level command. This command is separate and unique from Legacy absolute speed commands. (TMCC gives you a different result because in that mode, the same relative throttle up/down messages cause changes to both speed and sound.)
It would be my guess that the current MTH support for Legacy products sends absolute speed commands, but never sends absolute run level commands. On a related note, I would be interested to know if Legacy steam locomotives change their chuff laboring in the TIU/WIU environment, or if they sound at a fixed labor.
Absolute run level commands and engine laboring commands are sent from the CAB2 and also from from Apps like Lionel iCab and HighRail. Perhaps MTH will add this functionality in a future version--the commands are published in freely available Legacy command protocol document.
