Hello,
I was just cruising around in a DF server, but my FW (D9 model) BARELY made 400 kph at 2000m. In the FB object viewer, the D9 is supposed to go about 575. So, my question can anyone tell me the basic CEM procedures for the following situations:

After take-off, I wanna have maximum power for climb. What should the CEM settings be?

At alt (mostly about 3000m), I wanna cruise at maximum speed possible

After spotting the enemy, I dive on him, miss (offcourse ^_^), and wanna have maximum power for the zoom climb.

After really screwing it up, the enemy is at co-alt, behind me. I wanna squeeze every KPH out of my plane.

Can anyone answer these questions? I read something about CEM, but it was quite theoretically. I want some practical info. Anyone?

One of the advantages of the Dora is the CEM is automatic. If I close the radiator, put on Wep, and hold it level. I can get over 600 km/h easily on the Dora. I'm not sure why you can't do the same.

Supercharger is full auto, but prop pitch can be adjusted, so I would suggest you to increase a little bit your prop pitch on take off and climb, and lower it incrementally during level flight...try it and see if it works better...

Did some test flights... Fw190D9 1945 alt: around 1100

CEM off:110% throttle, MW50 on, radiator closed/auto
accelerating from level flight: doesn't really get much past 400... Got to 420-30

CEM on:110% throttle, MW50 on, radiator closed
accelerating from level flight:
fairly fast to 400, slowly to 500, after that VERY slowly upwards... Got to 570, then it overheated.

Hmm shall try the prop pitch thing then... Let me see.. lower is for less power/more speed (high gear), and higher is for more power/less speed (low gear), right?

Leave CEM on, but youwon't gain much by playing with the pitch. It has a constant speed prop like the La7. Not much to be gained by playing with prop pitch except economy.

That´s right. I.e, on take off, you need all the power, but not that much speed, so high prop. pitch...once high and level, you need speed and less power, so lower prop pitch...it also helps with fuel consumption during long flights, as well as with overheating.

I get over 600 km/h at 100% prop pitch. Changing it won't get me any more speed. It's not a manual prop like the 109E.

First thing as Buzz said is to close radiator, then throttle back below 50% power, engage WEP and power up to 103/104%. That should let you fly fast for a long time. Don't hesitate to climb a little more and gain speed by pushing the nose down a little.

No No Buzz, constant speed props only on FW190A series. The FW190D9 (water cooled engine) has same system as Bf109s in FB. You should like them D9's, they like a luxurious K4.

Turn off the 'automated system' by Shift0(default). Set your throttle (power) at a high percentage (for max power), and constantly manipulate your RPM (prop pitch) to keep them around 3000 (3200 max safe I believe). Keep on top of that RPM guage, or you'll blow that engine, its a real powerhouse. I can't be sure but I think 2600 rpm is cruise (with similar reduction in throttle).

Experimenting with the prop pitch... Blew my poor engine to kingdom come TWICE with the 100% prop setting XD

at 1000m with the 1945 D9, level flight
580-590 with 110% power, MW50 enabled, with prop pitch at 50%-60%, able to get 610-620 in a very shallow dive with 40%-50% prop pitch. More speed than indicated in the object viewer. Are these the maximum speeds that everyone is having?

And what is a good pitch setting when you're doing manouvres? 100% seems to be very nasty for your engine...

Well most people say the Dora better flown @ 103/104% throttle than at 110%. You may want to try that first.

Hmmmm.. I'll have to do more testing. I thought the Dora was like the A series.

Use P.P. like shifting gears in a car.Keep the rpms in the powerband.You can reduce that maddening delay you get when moving the throttle back and forth too.

All this stuff really adds a whole new dimension to it. Now I know why real cockpits have levers for this stuff and no stupid alt-number combinations! ^_^

Prop pitch auto, radiator closed, throttle 103%.

Note that the object viewer is talking about True Air Speed (which you can only see in the no-cockpit view) and this is different from Indicated Air Speed (what you see on the guage in the cockpit as well as the HUD in lower left). And yes, TAS is different from IAS even at sea level, contrary to what a lot of people will say, because temperature effects it as well, different maps are at different temperatures, and I don't think any of them are at the temperature where TAS=IAS at sea level.
