Engine stalls at low temps 2024 only

Version: 1.6.43.0

Frequency: Consistently

**Severity:**High

Marketplace package name: N/A

Context: On the ground at idle thrust with temperatures lower the -8 degree Celsius

Similar MSFS 2020 issue: Does not occur in MSFS2020

Bug description:

Whilst fine tuning our engine parameters, we’ve hit an issue in MSFS2024 that does not occur in MSFS2020

With our engine model tuned to match the real aircraft idle N2 at ISA, if the ambient temperature gets below minus 8 degrees Celsius, every 20 seconds the engine params drop as if they are about to stall but recover. Our flight model expert has attempted to resolve this by adjusting other parameters, but the only fix seems to be to increase the lower N2.

Idle params are as follows at ISA/Sea level:

N1:24.1%

N2:52.9%

Repro steps:

Load in any aircraft with the privately attached engine.cfg and reduce the ambient temperature to -8C or lower.

Could we get some acknowledgement of this at all? We’ve found a work around by bumping up the idle N2 by a percent but its no longer quite accurate to the real world idle values at ISA/Sea level

Hello @Hodgeheg4424 ,
I was not able to reproduce the issue using our samples.

Could you please share with us your 2020 package ?

Hi Boris.

The issue is relevant to 2024 rather than 2020. I did send over the relevant Engine.cfg via the private DM. Did you recieve this?
