That's not true IRL, why would it be in the game? Different bodies are going to have different airspeeds where the wing is, different methods of keeping the laminar flow attached all the way to the rear of the car, different deck angles (and thus different ideal wing angle)... in general terms it'll perform the same, but that can only get you 90% of the way to an accurate simulation.
No, IRL the same wing does get used on different cars with different results. The results are different but the wing is the same.
I believe you are totally missing my point about how the sim engine should handle the file data.
I am in fact using the VERY SAME wing on my car IRL (a C5Z) that has been used on many C6Z's and even at least 2 Ferrari 575's I know of..
The SAME WING. The wing works on all the cars - just differently. But the WING is the same.
So if the sim engine was truly a modular sim engine then I should be able to use the same WING file on 2 different cars.
The wing brings a set of raw down force/lift and drag data based on AOA with it - data that is separate from the changes the car the wing is mounted on will have.
It should be up to the sim engine to APPLY the WING file data to the car and then have the appropriate different results based on the CAR the wing is applied to.
In real life we didn't take a syringe and inject C5 Corvette DNA Data into the wing, the same way C6 DNA Data or Ferrari 575 DNA Data was not injected into the wing to get the results the wing gave on the each car - each CAR the wing is used on caused the wing/car combo to behave the way it did.
The WING is the same wing. But the results are different due to the car.
Therefore the sim engine should APPLY the wing data to the car and then compute the resulting wing/car combo
If it doesn't and the WING data needs to be tweaked for each car then again this is NOT a modular sim engine.
To be sure - the wing doesn't bring different data to the each car - it brings the SAME data to each car, the DATA just has a different impact on the car - this is what the sim engine is supposed to handle, the WING file should not need to be changed to correctly reflect the change.
If it does need to be changed then the sim engine is either broken or deficient in that area.
The only time I would expect to have to edit the WING file is when a change is made to the wing itself, perhaps a temporary change like AOA (which really should be handled by an in-game slider to make changes at run time) or a more permanent one, like in REAL LIFE when I added a Gurney flap and changed the side plates on my wing. Now the wing has a different set of DATA due to these physical changes.
Later the Gurney flap was removed and the side plates changed back and the behavior of the car went back to the previous behavior because the wing was changed back.
Again, this behavior change is what the sim engine should be handling, not the WING data file.
But either way, I have already conceded that if AC requires me to tweak per-file per-car all wing, tire, engine etc. data then so be it. It just means its not a modular sim engine, that's all
