Engine Settings Wrong/Information mix up.

[HR-Crumble]

Hi all I have been looking at learning the Corsair to find the engine management power settings for MP/RPM/Fueling all at the different alts. 
 

The three sources I have are attached in order:

1. The actual Magnitude supplied manual. 

2. A digitally replicated (from user files) of the stamped card inside the modules cockpit left hand side.

3. A regularly quoted and provide F4U-1D with the water injected engine ACTUAL flight manual.

If you look closely the most common power and engine settings differ for Take Off/Rated(max con)/Cruise/Economy cruise.

 

Can anyone, preferably Magnitude, please provide us with the correct settings to use.

Take for example the Max Rated settings - the cockpit card shows a different fuel mix to the actual IRL manual. Next, take for example, max cruise - all three sources show different MP/RPM/Fuel mix settings.

 

How can the internal cockpit card be different to the actual magnitude manual and be different to the actual IRL manual.

Magnitude please can you help us out and clarify so we can get the most out of this awesome module - as you know warbirds engines are delicate and you need to master and rote memorise the settings but you can’t do that if the source material is all different.

There's definitely problems with the modelling.

Trying to run WEP at full RPM overboosts the engine and causes it to knock. It very much shouldn't be doing that. Also, WEP should be at 2700rpm all the way up, as shown in the actual flight chart, NOT 2550 as in the kneeboard data.

The actual flight data shows different blower settings from what the module uses, as well. WEP blower should be neutral below 8000ft, not Low at 5000. Boost is also too low in the kneeboard data, with 57.5in below 8000ft, 59in between 8000-17,000ft, and 59.5 above 17,000. So once again, that kneeboard data is wrong, and if that's what the engine modeling is based off of, then the modeling is incorrect, as well.

Which means right now the Corsair isn't able to get all the power from the engine it should be because you can't use rated power settings without killing it.

Thanks for the reply and the details. So it seems there are inconsistencies with the data sources as well as the model. 
 

can I ask which settings you use for Rated, cruise and WEP then in order to not damage the engine?
