Density_on_torque_table = not funtioning in engines.cfg

[MSFS 2024] Questions & Community Discussions Aircraft

Version: 1.6.30.0

**Frequency:**Consistently

Severity: high

Context: IRL performance charts are available and used, but if I can’t tune this, it leaves unrealistic high alt performance

**Bug description: **
tuning using thhis table inside the Engines.cfg for a turbine heli

density_on_torque_table =
0.001065:0.44, ; 25000 ft
0.001162:0.48, ; 22500 ft
0.001266:0.50, ; 20000 ft
0.001377:0.55, ; 17500 ft
0.001496:0.60, ; 15000 ft
0.001621:0.65, ; 12500 ft
0.001755:0.70, ; 10000 ft
0.001897:0.20, ; 7500 ft
0.002048:1.00, ; 5000 ft
0.002208:1.00, ; 2500 ft
0.002377:1.00 ; 0 ft (SL)

I wasn’t making progress on tweaking so I placed in a stupid value. ie 20% power remaining at 7500’.
performance is very similar to sealevel performance.
its like this parameter isn’t functioning at all

Repro steps: Tried different values. same consistant result.

Hello @StuLes20

Is this how you have it formatted in your cfg file or is for the sake of readability?
Because this will not be handled well by the config parser, your table needs to be on a single line.

Hi Sylvain
I tried different formats. The one above was included for readability.

density_on_torque_table = 0.000225:0, 0.000587:0.8, 0.000739:0.83, 0.000891:0.89, 0.001144:0.93, 0.001268:0.970, 0.001496:1, 0.001756:1.025, 0.002049:1.050, 0.002377:1

this format is accepted by market place, and it is what we have been using for the last 2 years.

Problem is that putting in extreme values show no noticeable difference. So I am questioning if its functioning at all.

Thanks
Stu

Hi Sylvain
I am not sure why, but now it works.
I got pedantic, and used only the example densities, no interpolation.

Thanks for responding.
Sorry to waste your time.

@StuLes20
A tip here is to look at the debug=>aircraft=>engine
the highlighted in red will show you the effect of you N1 & mach table under current conditions

Hi
Thanks for the input. Appreciate that you took the time to help.
Sorted it. Not sure how. When I removed the addditional densities, it worked.
