SIOC script for Fuel Temp Servo ?

[markusr]

Hi guys,

iam trying to find a sioc script that works for the Servo cards to display the actual Fuel Temperature.
How can i calculate this?
I can use the OAT temp to calcualte the fuel temp. But therefore i would need a good formula.
Any ideas? I think the positive is not the problem. When we have an OAT of 20°C the fuel has also 20°. But the negative would be the interesting one.
When i have -40°C how cold is the Fuel in the Tank??

Or if this is too complex, i would go for the first one with the OAT i have figured out the following:
°C(in FS) = varibale $0E8C = variable $0E8C/256 ( variables from FSUIPC Guide)
75°C = 19247 = 50
60°C = 15407 = 40
30°C = 7727 = 30
20°C = 5167 = 20
10°C = 2607 = 10
0°C = 47 = 0
-10°C = 63024 = 246
-20°C = 60464 = 236
-30°C = 57904 = 226
-60°C = 50224 = 196
-95°C = 41264 = 161

But how i can control the servos, when the values are going from + toward 0°C down to 0 and than jumping back up to 63024 and going further down to 41264 ???

Hopefully you can understand my description...
Would appreciate any ideas from you.

Thanks,
Mark

Marc,
please sent me a private message as reminder. I will send you my SIOC script for the fuel temperature in a couple of days.

This is interesting, .. I'd like to take a look at your script too, .. not that I am that far in my project yet.,.... but I like to jump around from one thing to another

Hi folks,
SIOC code for the PM fuel temperature gauge:

/////////// Fuel Temperature Gauge /////////////

var 0215, name Servo2, Link USB_SERVOS, Output 2, PosL 1023, PosC 436, PosR 150, Type 2 // Servo Motor
Var 0218, name FuelTemp, Link FSUIPC_INOUT, Offset $56B6, Length 2 // Fuel Temperature + 60 in 10th of C
{
L0 = &FuelTemp / 10
L1 = L0 - 60
L2 = L1 * 6.4 // servo slope
L0 = 550 - L2 // Center 0 Grad Celsius
&Servo2 = L0
}
