    Go to the SoundTraxx Steam Sound User Guide : http://www.soundtraxx.com/manuals/tsunamisteam_users_guide.pdf
    Look on pages 58-59 and 60. This might help you.

    I have that guide downloaded so I will look at those pages. Thanks! Sometimes I just need to know what to do when X happens. The user's guides tell you how to change things and what you may change them too, but not often much on what to do if in X situation Y happens.

    Thank you,
    Adam

    Forgot to tell you that CV116 will change the chuff rate. Try using a value of 100 or so. Hope that you are using Decoder Pro! Makes taming a Tsunami much easier!

    Well, I fiddled around a bit programming in OPS mode tonight those CVs mentioned in those pages, and I broke the 10 smph barrier. I got up to a very respectable 55-60 smph, which is about as fast as I ever want to go. I have the chuff mostly right. I can't remember if I had programmed a speed curve which does have om bearing on the chuff rate adjustment method. I will take a look later. Thank you, woodone, for helping me determine which part of te annual to apply. I had read the thing, it I was not clear on which section was the applicable one for my problems. I was trying to approach it through speed settings, which was not unite the answer.

    Glad you have it running the way you want. One more thing- if you operate the unit for a long time you may find that the decoder will overheat and shut itself down. I have found that using a piece of aluminum and mounting the Tsunami to it stops this from happening.
    The Tsunami's have more CV's than you find in a magic hat.

    After problems like that initially, I pulled the tender back apart, added the optional capacitor and mounted the decoder to a piece of brass stock that I had on hand. The overheating seems to have gone away. This was a few years back. Yesterday was a good test, as it was 90 F in the clubhouse and it never cut out.

    Somehow in all of that I screwed up the tail-light. I am trying to decide whether I care enough about that to pull it all apart again and replace or repair that. It's kind of hard to shove it all back in the tender, which is why I am hesitant.
