Crap! According to this it's -27'C...actually it's +20'C. Try to correct manually and it crashes....4 times. Reinstalled and got the same. Manually put weather data in and the jet suggested was way too rich. No adjustment or fine tuning let alone all the options available etc. Waste of time like all the other crappy 'apps'. Got Jet-Tech PRO instead - utterly accurate and professional software.
Too rich Main jet is too rich, so the engine runs like crap
Crashed upon start
