I downloaded the 4.4 version available in the Ask Question section and it works perfectly fine. Also, I really appreciate the possibility to change the units for pressure, temps, speed and fuel. One thing that could be improved is the size of the speedmeter and other windows that I find a bit small and we can't enlarge. Other than that, great HUD, maybe one of the best out there!!
Mare sure you do at least 2 laps in a session, without restarting from the pits, that way the laps will count.
