Bachmann Pannier Tank CV values

[cowside]

I'm still trying to find the best values for CV2 to CV6 for a Bachmann pannier tank running under DCC with RailMaster.

What values do our experts recommend for CV2 to CV6?

[Howbi]

Which decoder are you using?......What is wrong with the default values, I rarely find it necessary to change any of those from default on any make of decoder other than CV29.

I'm not even going to try to give you an answer, but those who can, are probably going to need more information such as:

1. What decoder is fitted.
2. What are the current CV values.
3. What are your running issues that you are trying to resolve.

EDIT: Howbi got in with his reply just ahead of me. Like Howbi, I have found default factory values perfectly fine and have had no need to alter them.

Thanks for replies. I'll reset decoder to factory values and see what happens!

Later ..... factory defaults (DCC Concepts Zen Decoder) have improved response greatly. Interestingly I had a Class 52 Dapol with a Rails/DCC decoder and it hardly moved with default decoder settings. Had to adjust CV2 to CV6 to resolve.

When I started in DCC I was told to adjust CV2 by the following method.

Set speed step 128. Turn speed up 1 step at a time. When the loco just starts to make a note of the speed step reading. E.g. 4.

Change CV2 to 4. Test, repeat if required

CV5 limits the top speed so a class 08 won't move as fast as Mallard.

CV6 is the mid speed try 30 to 40% of CV5.

CV3 and 4 are very subjective. In my case above 5 or 6 and they take ages to slow down. The size of the layout in my view dictate their setting.
