When flying the A2A Bf 109E-3 I am able to set rpm using the pitch lever. I use the throttle to adjust boost. Pitch has fine adjustments as viewed on pitch "clock". Overrevs don't seem to be an issue given the range of pitch adjustments. In COD the situation is much different. Pitch seems to have only three settings. The pitch "clock" sometimes does not change with pitch lever settings and the engine seems to over rev without much warning, sometimes at the start of a mission without my seeming to have done anything to provoke an over rev. I am not sure which of these engine management implementations is correct but the A2A version seems much more predictable and less frustrating. Any insights would be appreciated.

I assume you have CEM enabled? Full range of pitch is capable, from 8:30 to 12:00. Depending on the situation (take off, steep dive, throttle/boost settings) it is easy to over-rev or bog down the engine. If your pitch isn't changing, either your control is set up wrong, or you don't have CEM enabled. I'd advise against setting the pitch as an axis, try keys for Increase Prop Pitch and Decrease Prop Pitch. I find with using a slider set as an axis control, the game (or maybe my stick) has a problem with identifying the proper placement of the axis for the pitch control. What I mean is, its hard to find the center spot to stop the pitch movement, sometimes, in the heat of battle, I wouldn't have set the axis back perfectly, and the propeller would continue to increase until fine (at which point I'm overrevving the engine during maneuvers) or decrease until full coarse (which leaves me with no power to accelerate). Both are potentially fatal problems you can avoid by setting keys (which I then set to a joystick hat switch).

You should have no problem setting RPM with a constant ATA within the limits of the engine power vs velocity.

No probs here whatsoever.

I have Prop-Pitch mapped to two buttons on my PC-Dash 2. Every setting between 8:30 and 12:00 is possible. I understand though, that manual prop-pitvh was replaced with automatic systems, as especilly in the heat of the battle, errors might happen quickly, f.e. over-reving in a dive.

What cheesehawk said, check if you have CEM enabled and if so, check your key-mappings.

works fine for me, have it set up on the throttle ministick axis, works brilliantly through the full range.

Thanks! I mapped pitch to keys as you suggested and it works as you describe. I then mapped radiator to the freed axis and notice that to stop the wheel at the desired setting the axis knob has to be returned to center. Maybe something similar happens when pitch is mapped to an axis.

You're welcome, glad we got that worked out for you. The CEM is one of the better things about this game compared to its predecessor, it would be a shame to not realize it!
