Supercharger Settings

[ATAG_Dutch]

I was height testing the Spit MkII the other night, with full CEM and overheat effects, with some other members here;

I found that I couldn't get above 22000 ft, the engine was stuttering, and the A/C was shaking about unbelievably.
This has become a bit of a project as obviously the Spit had far more altitude capability.

No matter what I do in the controls menu, I can't get the two speed supercharger to be selectable between low and high gear, and the carb heat function doesn't seem to work (although I don't actually know whether this is a factor).

Can anyone say for sure which controls to enable to get the two speed blower to work?

Cheers
