Testing with CEM off is useless and irrelevant. Were all your tests done that way?

Tests should be done with full CEM and full fuel loads from a takeoff as close to sea level as possible.

I would ask you again to link me to your tests, with the details of exactly what the parameters and conditions were.

I know your point, but without more information on the internal system, who's to say CEM being off is wrong?

Agreed here, if IL2 programming is in line with CEM being the best tuned outcome performance wise, it's actually 'better' to test this way as you're getting the best result possible with all factors perfectly tuned. CEM may just be a simple 'disabling' of the inherent automatic controls, that's my feeling. There seems no point in making Auto CEM performance any different to manual CEM.

My preferred way to test the 'best performance curve' is away from any influence from poor pilot manual CEM and/or engine DM/heat effects.

Of course drag items like cooling flaps would need to be set as per the data you are using.

Wish we could be 'told' how this Auto/Manual CEM functions, that would define it for testing.

My tests were done with CEM on. I did a CEM off test to check how the AI would handle prop pitch, that is when I noticed the serious discrepancy.

I created a simple mission in the FMB, one aircraft over the channel at 500m. No wind or turbulence set in the weather. I know it is hardly scientific but I tested all of the fighters and only the Spitfire Mk IIa, Bf110 and Hurricane CSP (Rotol) achieved their rated speeds. So if there is a problem with the atmospheric conditions in the test it should effect all aircraft the same.
