CV21 and 22 control which functions are active in an advanced consist, using CV19. Generally you do not want to change these from the default when using NCE consisting.
This should have no effect on speed matching. What DOES is is one of the decoders is Digitrax. They have 2 different sets of BEMF control variables. One is used when running alone, or in any sort of consist that doesn;t use CV19, and one that applies when CV19 is used tooo consist the loco, such as manual CV19 consisting or when NCE consists the loco. By default, these are not the same number, so you might have the loco running perfectly fine running alone, but when you consist it, the performance changes greatly.

There is another thing that no one has mentioned that can cause an issue with consisting locos with different manufacturers. This has to do with CVs 21 and 22. I can't thourghly explain it myself, but there was an article in MR not that long ago that went into some detail. It had to do with the fact that even though different decoders might do the same thing, they had different ways of accomplishing that thing. o when consisted they would not work well with each other.
Perhaps Randy can explain.
You should be able to speed match any two engines, regardles of the maker of the engine or the decoder. One thing when speed-matching - especially with different brands - is to make sure you're not using speed tables / speed curves. Both decoders should be set to straight line speed curves (if it can't just be turned off), and use CVs 2,3,4,5 and 6 to get the engines to start, run, and stop together. If one engine has been set (intentionally or otherwise) to a curved speed curve, you'll never really get them matched.
That’s another thing I was wondering about. I was hoping there was a cv for the tsunami 2 to rev up the motor sound before the locomotive moves. I tried to get information from the Soundtraxx users guide but I might as well try to read Tolstoy’s War in Peace. I talked to customer support about another problem and he sounded like I was being a bother to him so I really don’t want to deal with that .
TCS motor and Loksounbd sound ought to run pretty close out of the box, especially on the same loco.
Close is good enough - and out of the box they both need some run time. All locos need a little break in time, with Loksound you should also do the auto-bemf tuning, and TCS also auto-tunes the BEMF while the loco runs. Loksound you need to set a CV thent he loco will appear to take off by itself for a short distance while it does the tuning.
All my non-sound locos have TCS decoders - the first few feet after a new install, they run kind of rough until the BEMF tuning finishes, then they run great, start on step 1 with no additional settings, etc.
RR_MelI believe consistency makes life easier in the long run.
After doing what I've done, I agree with you 100%.
I bought the E8 A unit from Kato with a factory installed Loksound decoder. They had a B unit there also, but I decided that I didn't want to spend the extra money for a B unit with sound.
I bought the KATO B unit with a TCS decoder.
Big mistake! I should have just paid extra for the sound B unit. I spent literally hours trying to get the speeds matched. I'm pretty close, but there are still times when I hear one of the locomotives running either faster or slower than the other.
Live and learn.

Life will be easier if you settle on one brand. While there are standards for CV's there is also latitude for proprietary differences, like the loksound delayed start or the Tsunami Quiet Mode.
Not much of a problem now, with 2 locos, but they multiply like rabbits over time.

Davidarps So I have a tsunami 2 decoder installed in one of my locomotives. I’m putting an ESU Sound lok in another. I’m a little new with this but I don’t see a problem. Does anyone else.

Being fairly new to the hobby, I had the same question a while back.
You can get the speeds to match, but it does take time. It helped that I had a double mainline, so I could adjust each locomotive's speed compared to the other. Even with that, it still took time.
My locomotives were an E8 A and B unit that I use in a consist. They still aren't exactly matched, but they are close enough. In the next day or two I will try to adjust their deceleration rates.
Both have options for matching the speeds so that won't be a problem. The Loksound has a delay when you turn up the throttle that allows the prime mover to rev up a bit before the locomotive moves. You'll probably want to reduce or disable that.
Try CV 124 = 0 , I believe.
Otherwise, have fun.
