I have 2 of my LGB Shortie Loco's with LGB decoders in them. They both have different driving characteristics, and I want to set them so that they both drive the same. I have tried altering the driving curve but to no avail. The only CV that seems to make a difference is CV 5
So My Question is.
1: How do I set the decoder back to factory settings?
2: How do I match them up? as I thought if I alter the driving curve that would do the job.
3: What am I doing wrong?

Over to you.

Hi Steve,

Write 55 into CV 55.

It should do.

You have to write one of the bits in CV29 in LGB decoders to enable the user defined speed steps curve. Add 16 to whatever is being written to CV29.

Hope that helps.
