MRC DCC Help

[lmackattack]

i have a quick question about my MRC advanced squared DCC. when programing my decoders i am having trouble understanding how the start,accel,decel, max voltage is calabrated. i can get all my locos to run the way i want after i reprogram a few times but i cant seam to figure how the numbers coralate on a scale from 001-999

i just go off of the decoder mfg suggested numbers and go from there
hope i made sence

Thanks

Most of the time, I leave those cv's set to default settings. The only time I mess with them are when I have a unit that runs too fast or doesnt start up well.
For a unit that doesnt start well:I will set the start voltage at 8~10 volts, accel 1, decel 1, and top voltage 14.
The settings for the too-fast runners are dependant upon the decoder.

First, you really must get into the manual and read it. For this question, what you must learn is how to map out speed tables and to programme a value for each of the speed steps. It is a daunting task, and few of us do it. But, if you want your engines to match their contributions to the tractive effort in concert, you must do this, either with fewer 28 speed steps or with the full meal deal at 128.

Not for the faint of heart.
