Hi all,
I've installed a Tsunami TSU-1000 decoder in an Athearn bluebox C44-9W recently.
While everything went fairly painless, I'm struggling with the speed control. It
has probably to do with the quality of the motor, but I just can't seem to get
the BEMF function set properly. Default this is '0'. Using this value the loco
'jumps' in small steps, a bit like what happens in programming mode, and the
sound goes on/off with it. changing this value to 20 meant the loco didn't move
at all, could hear the motor hum and the engine sound revving up/down.
Increasing the value to 80 gave me a rather rapid start and no slow speed
control. I've been playing with values in between but not much luck. Does anyone
have (had) similar issues and how have you solved it? Cheers!
