I have come up with fixes for two of the TBM930’s issues.
To implement these fixes, edit the specified file entries to the specified values. You must edit the current entries - do not just paste these lines into the file, unless you paste over the original lines, or you will end up with duplicate lines.
The files to be edited are in this directory:
Suggest backing up the files first.
First fix: This fix will correct torque vs air density (torque will decrease during climb and increase during descent) and will also cause ITT to become limiting at higher altitudes.
Edit the TMB930’s engine.cfg file as follows:
high_n1 = 110
itt_peak_temperature = 2540
density_on_torque_table=0.000737:0.141, 0.000889:0.188, 0.001065:.241, 0.001267:.316, 0.001496:.42, 0.001755:.55, 0.002048:.72, 0.002377:.965
n1_to_shaft_torque_table = 0:0, 68:.07, 86:1.0, 110:4.7; Corrected N1 -> Shaft Torque
Second fix: This will cause the landing gear to create drag.
Edit the TBM930’s flight_model.cfg file. In the [AERODYNAMICS] section:
drag_coef_gear = 0.04700
Update: As someone pointed out, and I forgot to state, because these changes allow for a more realistic higher power setting at high altitude, fuel burn will be about 25% higher. I was unable to correct the fuel flow, so maximum range is reduced by about 25%. If this will affect how you use the TBM, then don’t apply these changes.
