OOOPS... i didn´t put this information...
The DCC system is MRC(not sure about what exact model, i will check this with the owner), but  i´m almost sure of the ability of the DCC system to read/program the values of indicated CV´s...
I will check the current values and i will post here the results.
Thanks for help!

Hi,
There's my first post here in discussion boards,
and i hope finally find someone who has the answer to my question.
I have 3 Bachmann engines with DCC onboard ( GP35,SD40-2,GE 70Ton.)
and i recently have programmed the SD40-2 to run in a layout with DCC.
After this, the engine doesn't run in any layout with a DC controller, only in DCC.
Any ideas?
Thanks in advance,

Eduardo
