Carburetor Controls Working?

[13sq*Axe]

Greetings all, I was reading about the carburetor controls needing to be mapped to an axis or a file modded to function. That moving the levers in the cockpit with the mouse or buttons would not work. Has this been addressed in updates? Thanks in advance!

The problem with the ram air control not working properly when bound to a key press was resolved quite a few updates ago, so you should be all good.

Thanks for the quick reply. Using the mouse works also?

Yes, it does. Thus, it might not be worth "wasting" an axis, unless you have plenty of them on your HOTAS. You won't be using this control all that often, if ever (carb icing is not simulated in DCS).

Thanks so much!

The Carb levers work now just fine. You should map the Ram Air to an axis; it will help with manifold pressure when you are high up after the supercharger kicks in. There is a tutorial here or on YouTube where I learned that trick. I could be wrong on either of them, but get up to altitude, get the SC to kick in, and watch for the MP to start dropping as you go highter. Then adjust the RAM air first and see if the MP rises. If not, then try the Hot Air lever. You will see it increase with the correct lever.

Supercharger is directly connected to crank shaft so as long engine is rotating supercharger is rotating too. You can check RAM at every altitude as long as plane is in the air.

Only thing you need to do is to retard throttle to obtain less then 42" of manifold pressure because above 42" automatic boost control is engaged and you won't see RAM effect on manifold pressure. Set it to 30" and move ram lever forward and backward and you will notice increase and decrease. RAM depends on aircraft speed so faster you flying greater RAM effect you will notice.

Sounds like fiddle-factor to me.

Ram Air, as opposed to Filtered Air.

If not in the process of operating from a dirt/sand strip?

Set it to Ram Air, and spend the effort on actual flight mgt. systems.

There was a problem with RAM air in P-51 so from time to time i run this check then i know for certain that it works. RAM air bug was nasty because when you moved levers in to ram position it didn't get the ram working and only way to quickly check it, is to drop MP to 30 inch and cycle lever back and forth  and if you get change in MP then you are good to go.
