F40PH RPM control

I should of stated the control is DCS WIFI on an Android tablet.

Have you tried using the Rev up/down button on the app?

Yes, the Rev up/down buttons in the app adjust the revs when the speed is under 35 SMPH.  Over 35, the buttons have no effect.

Is this behavior the same with a DCS Remote?  I only use the WIFI app.

It should not be different between the remote and app. Have you tried factory resetting the locomotive?

Does the engine seem to run at full speed above 35MPH? Do you have good speed control from say 35 to 50MPH?

I think I remember there may have been sound sets with only four engine speed notches?? You may need to load a different sound set.

I believe my Amtrak versions has the 8 engine throttle notches? I'll have to go check.

or re-load the soundset. is this it?

Thanks Joe,

The engine has all 8 rev notches that can be turned up or down using the Rev Up/Down app buttons, only when idle.

Uderway, the Rev Up/Down app buttons sometimes work at low speed, but they never work over 35 SMPH.

The engine runs very smoothly between 35 and 50 SMPH.

Can you adjust your engine revs using the app Rev Up/Down buttons, while traveling over 35 SMPH?

I don't have a DCS Remote, but I am wondering if the revs can be changed using the physical buttons on the remote?

Thanks

I think you're hearing the high rev sound file and just don't like it! I made a tape of it (sorry it took an hour) and will post for you to hear it. It sounds realistic to me but it has much higher frequencies (all of them) than older files.

I'd have to suggest changing the sound file but you may loose lights or mess things up? Don't touch the chain files!

Can you show the same sound changes on a video Joe while at a SMPH at 45 ?  🤔

It could be hitting high RPM early because it's imitating the prototype. Passenger locomotives usually run at a constant high RPM for the HEP power for the passenger cars.

So if this is true that the app can't lower the revs, than you have to turn down the volume or swap out the sound file.

The only other fix I could think of is to tape off the speaker below so that the high pitch frequencies aren't as loud. It would be easier to just turn down the volume.
