    Have a couple of Kato SD70ACe’s that I’d like to TRY and speed match.
    One, UP 1943, has a TCS board, installed by me.
    The other, UP 4141, has an ESU board factory installed.
    I’d like to try and speed match the ACe’s if I can, or at least the 4141 to my UP844.
    A difficult process? Or easier, with decoder programming software?
    Would have to set up laptop for programming, if necessary. And find programmer(s).
    Then try and figure all that out!
    Anyway, help and/or information much appreciated.
    Thanks.

    The first dependency is whether the TCS board has the firmware on it that fixes the speed table glitch. If it does, the best way is to create linear speed tables in both. Check for linearity of response in the TCS first and get it set to the maximum speed you want (or its maximum). Then, set the ESU to a linear speed table, and simply adjust its maximum speed, CV5, to match the unit with the TCS. Of course, the TCS cannot handle startup delays, drive hold, etc., as do the ESU decoders. Depending on which decoder, the acceleration and deceleration values may be different.

    Rick, do you know the firmware version in TCS that fixes the speed table glitch?

    I don’t. I just know some of their “newer” decoders have this fixed
