Hi all,
I've spend hours and hours, but this one is just did not work well, with all the tuning and tweaking (including the mechanical kinds).
In the end, I've decided to replace it with a mashima. The motor swap took about 1 hour, and then the programming and fine tuning of the DCC decoder no more than 20 minutes, and it runs like a dream now. Still odd that it ran fine with the TCS decoder, but was untamable with the Tsunami. I guess the BEMF and other control settings of the TCS were better suited to the Athearn motor. Anyway, all is well now and I've got a good running GP38-2 (yes I mixed up two projects, my CW44-9 mentioned at the start of this thread has the same decoder and an Athearn motor, but it runs fairly reasonable, the GP was the one I struggled with) . On to the next project :-)
