The mach dial rotates based on pressure altitude using the property /instrumentation/altimeter/indicated-altitude-ft see https://ewhdbks.mugu.navy.mil/mach-as.htm . The scale is calibrated so once the dial is set for a given pressure altitude it doesn't need to move until the altitude changes. See the file Models/asi.xml its already set up.
