Hello,

I’m trying to set up a servo for the fuel temp gauge.
, I have the offset but don’t know what parameters to use. Can anyone help

Hello Sreen,

we only tell you when you tell us which simulator (FSX, P3D, x-Plane etc) you are using and which one (Standard, PMDG, Aerosoft etc)

Hi,

I’m using pmdg 737 in p3d v4.3.

Thanks

Hi

Offset: 6458 Size in Byte 4 Typ: FLT32 Name: FUEL_FuelTempNeedle

The gauge looks "Linear" in the Virtual Cockpit. So we not need interpolation (Just to protect overruns)


Create a Config (Output) but NOT use any Motor or Output device !!

Now observe the Offset with running Mobiflight.... In Different Situations. Check it for a Fuel Temp of for example +15 Degrees and - 15 Degrees ( Make a Cruise flight with timelaps to reduce temp.

Check the value you get. Is it a full number like always 13,0000 14,0000 and so on.... or does the decimal change to ?
How is the output value in negative situations.... Does it show -14,000 or does it jump to a verry high number if it should be below Zero ??

After that reserach you know the real situation of the offset value.... Then you can think about if a transform is need ( For example when negative values are show wrong)
Also you can define a Range ! Gauge look like from -40 to +40 So Settings for a servo may be Min -40 Max +40
Maby you also need a transform here like $+40 if your servo not accept negative values.
Finaly you maby need a protection of your servo.... If Value can get below -40 or above +40 in Aircraft BUT your servo use his 180° for taht range then it will turned again Endstop.
In That case you need a Interpolation or transform that a value below -40 is shown as -40 and a value above +40 is fixed also to +40 ... So no overdrive can happen

Please check the Value ..... Try to build the system.
If you have trouble please exactly tell us how the value work..... Then we can help you with the final settings in your config !
