Converting to DCC.

Sound value.  I've read that the TCS decoders are even better.  Hard to imagine how.  And yes, the smooth running at slow speed makes it nice and easy to manipulate connecting cars, navigating turnouts....etc.

Cv's 209 and 210 govern motor control.

This will work for any sound value engine, and for Tsunami before series 2.

1.  Get engine on a track controlled by a system that can change cv settings (no EZ Command)
2.  Set cv 2 (starting voltage), 3 and 4 (momentum), 209 and 210 (motor control) to 0.
3.  Set throttle to step 1.  Engine won't move yet.
4.  Try gradually increasing cv 210 value until engine barely starts to move.  It will be jerky.
5.  Slowly increase cv 209 value until jerkiness smooths out.
6.  Set momentum values for smooth start and stop.  I like cv3=100 and cv 4=50 but you may want more or less, experiment.

At this point that baby ought to start and stop silky smooth and crawl like an ant.

If things slip up you can always reset with cv8=8 plus track power interruption.
