Creating a Speed Curve
One common feature is to set a specific operating speed curve for
your locomotives. This is usually done to have dissimilar
locomotives have the same performance characteristics or to have
the locomotives perform more prototypically. Start by writing down
how you want to assign the internal speed settings to the speed
steps, for example by making up a table as shown below.
Note: CV2 (Start Voltage) is still used as part of the calculation
even when the decoder is in User Defined Speed Curve mode.

In 128 speed step mode the decoder internally averages the
speed table to obtain the correct speed step value.
