Iain S asked why the 44 seemed to jump away as it started to move in the first video of my last post.
The 44 is not mine and was one I had just finished installing the Tsunami decoder in and giving it a weathering job. I suspect the lurch was caused by paint on the wheels and then the power breaking through suddenly. I gave it a wheel spin in some CRC 2-26 later on when it stopped occasionally as it went around the layout which solved it. My44s do not have this issue.
Perhaps I should have redone the video after cleaning the wheels.
If you have a problem locomotive the Tsunami does allow adjustment of the BEMF CVs but this is best done using DecoderPro after you have saved the settings in your loco as the BEMF can get a bit confusing and needs to be adjusted carefully. Download the Tsunami technical documentation and manual, read it and well done if you can understand the BEMF instructions. A case of someone who knows what they are talking about not being able to come down to the level of most users when trying to explain things.
