Hi Reinhard,
Tsunami's can be very hard to tame to get the lowspeed ok. There are several approaches, but if you are able and willing to experiment, try this:
Start with everything set at factory default and no momentum (CV3 and CV4 at 0) , and input 50 into CV209. Then, put 1 into CV210.
Set the loco to travel at speed step one (using a 28-step speed input), and then increase the value of 210 until it runs smoothly. You may also consider reducing CV209 after that, to get it crawling along, without hesitation. After you're happy, you can then install any custom speed-curve using CV25 and CV29.
Note that, for getting the best results from a Tsunami (or any other sound decoder), some "delay" via CV3 and CV4 is required. This will also assist with smooth starts and stops. My usual values are CV3, 50-80, CV4, 30-50.
Depending on the make and model of locomotive, these two CV values should be tested in various combinations until satisfaction is attained. Note that each individual locomotive should be tested; don't assume that if one set of CV settings works in one loco, an "identical" one will perform in the same way.
