I have a BB Athearn SD40-2 with a Digitrax DH163 decoder. I have it running great by itself. This weekend I attempted to set it up as part of a consist (using Advanced Consisting on MRC ProdigAdv2). I consisted it with another BB gp38-2 with Digitrax decoder. When I selected the consist address and throttled up, the GP38-2 moved just as it would out of consist, but the SD40-2 did not even begin to creep until speed step 90, and managed about 1/3 throttle at step 126. I tried consisting with several other locos (one at a time) with different type decoders, but the result was the same. When I take it out of consist it perfoms fine. What do the experts say?
Default setting of the DH163 turns off BEMF in advanced consist. Check the full decoder manual here: http://www.digitrax.com/static/apps/cms/media/documents/documentation/Decoder_Manual_V2-01_2014.pdf
Page 48, there is a chart. Read CV57, and compare the value to the middle column. Add to it the corresponding value in the right hand column and set CV57 to that new value. For example, if it currently is 5, add 80, which means set CV57 to 85. Now you will have the same BEMF in consist as you do running single.
You can use a lesser value in consist, if so, just pick a value in the last column and add it to whatever CV57 currently is to obtain the new value. For example, if the value currently is 5, and you want to have BEMF in consist but at a 20% value instead of 33%, you would add 48, for a ttoal of 53, which would be the value to program into CV57.
