CV Configs for N Scale E8s

Model Railroader Layouts and layout building

I have just jumped into the realm of DCC with the purchase of a Digitrax Zephyr System. I have the two Kato CP E8s in N Scale with the recommended Digitrax Decoders (I can’t remember the model numbers off the top of my head but they are full functioned Series 3 FX decoders). My question is whether anyone can point me in the right direction as to what CVs and values I should program to give realistic control - top scale speed, momentum acceleration and deceleration etc - you get the picture! I also have a number of other N scale locomotives Eg Trainmaster, C Liners etc that I will have the same question for as I outfit them with decoders.

Any help in the above would be much appreciated.

Thanks

The commonly used CV are:
02 start voltage
03 Acceleration rate
04 Deceleration rate
05 Maximum voltage
06 Mid point voltage

CV 03 & 04 each value delays the change by 1/10th of a second. i.e. a value of 7 would mean that to change 6 steps would take 4.2 seconds.

I set my values differently for each locomotive, depending on how it runs. My yard locos are set lower than road switchers, etc. I did my trial and error for each one. Once you have set one it becomes a reference point for the next.

I recommend the book “Big Book of DCC” by Digitrax which goes into detail on all the CV’s that you are interested in.

Hopes this helps…Ken
