Model Railroading > Are all HO train engine decoders created =

I have 2 scaletrains dcc equipped engines and a walthers dcc equipped engine. They go around my layout going
up and down grades at the same rate of speed with or without being hooked up to a consist.

Received my first athearn genesis unit recently and just put it on the track . Unit slows down going up the grade and speeds up going down the grade.
Is this standard for this brand of unit.

Sounds like the Back Electro-Motive Force is not activated on your locomotive that is changing speeds when traveling up and down grades.   As noted on the dccwiki.com webpages: "Back Electro-Motive Force (BEMF) [acts] as a governor. This feature prevents trains from slowing down or speeding up on grades."

Check the manuals that came with your locomotives on how to adjuse BEMF.

If your decoders have this feature...

I'm pretty sure the Tsunami decoders have BEMF, but it may need to be turned on.  Tsunami is what comes with Athearn loco's factory equipped, or past few years Tsunami 2.

Those fatory installed may not contain all the features of what can be bought off the shelf for that same unit. Why? Ask Soundtraxx.
