Ok so I have acquired an LGB 92090 and installed a 55021 decoder. And it goes like the clappers - too fast in fact. So I want to throttle it in which I presume is by changing CV55 to something less than 255. I set it to 128 and now it's top speed is way less than half which is not the result I expected. Which leads me to my question is the scale for CV55 linear or logarithmic? If it is a log scale does anyone have a graph showing the value of the voltage for all values of CV 55 between 1 and 255?
thanks
