OIL Temperature failure

NOTE for Engine developers Having tried all sorts of values in the
engine.cfg - Oil Temp entries to no avail … My (Turboprop) Oil Temperature
gauge seemed stuck at a maximum of 32C ( even though the limit was defined at
700 Rankine / 115 C ) It seems the entry oil_temp_tuning_constant= needs a
value OTHER THAN 1 to become effective. for example … I have now entered
oil_temp_tuning_constant=1.01 and it is now reading in the correct 100C
+/- Range

Hello @ModelMuncher The TBM has that constant set to 1, and
oil_temp_heating_constant set to 600 and temperature goes above 32 (it
stabilizes around 35°C) so I’m not sure how you end up with this behaviour.
One important thing to note is that, for turbines, the temperature will
converge towards a target value (oil_temp_heating_constant) that is multiplied
by a coefficient based on N1 using the following table: 21.0, 0.980, 31.0,
0.946, 42.0, 0.935, 90.0, 0.905 So even when idling, the temperature would
stabilize lower then 700 rankine in your case. However, reading the code, I
really don’t see why setting the tuning constant to 1.01 would cause the
temperature to jump from 32°C to 115°C. If you can provide us with a package
that demonstrates this issue, I’ll investigate further. @Nocturne FYI Regards,

@FlyingRaccoon "The TBM has that constant set to 1, and

Yes this is exactly my point, With a Rankine of 700
( 115C ) The temperature “SHOULD” Increase to approaching this Maximum,
i.e. 115C and NOT 35c as you suggest … or am I missing something ?? IF I set
the tuning constant to 1.0 then the temperature does indeed stabilize around
32C but NEVER INCREASES Above 35C Ish … However, By setting the tuning
constant to 1.01 Then the temperature fluctuates as normal between ambient at
rest and 115C Max as expected under load
