I don't have one of those engines and can't answer your question, but if no one else chimes in you can query CV 7 to read the decoder's version number, then go to the QSI web site and get the correct manual.
Can anyone tell me, please, which of the manuals on the QSIndustries or QSIsolutions websites apply to this loco? (Sunset have not responded to my queries.)
Thank you in anticipation
