[FUEL SYSTEM] Fuel Flow gauge bug

Hi Team,

In our aircraft (single piston engine, and injection system)

When engine is cut off. Fuel selector to Left or Right or Both, Mixture rich, and boost pump ON, when you advance throttle, the fuel flow must rise a little, but it doesn't work on the gauge. I've checked with Simvar watcher and no fuel flow coming up. But aircraft can start correctly, fuel lines is OK, and fuel junction too.

Do you have any idea ?

[FUEL SYSTEM] has been done and working great by the way. But the fuel flow gauge still doesn't work at engine cutoff. When engine is running, the gauge is WORKING great !

Thank you so much.

For information,

the tag used for fuel flow gauge is the next:

<UseTemplate Name="ASOBO_INSTRUMENT_Needle_FuelFlow_Template">
   <ID>1</ID>
     <NODE_ID>Needle_FuelFlow</NODE_ID>
     <ANIM_NAME>Needle_FuelFlow</ANIM_NAME>
     <SIMVAR>ENG FUEL FLOW:1</SIMVAR>
       <UNITS>gallons per hour</UNITS>
       <MIN_VALUE>0</MIN_VALUE>
       <MAX_VALUE>27</MAX_VALUE>
</UseTemplate>

Hello @PESIM_Thomas

By looking at what you have sent, I'm pretty sure that the issue come from the ENG FUEL FLOW simvar which does not exist in the sim, you must use ENG_FUEL_FLOW_GPH or ENG_FUEL_FLOW_PPH depending of the unit you need to use (I assume you want to use the GPH one). With this fix it should work.

Best regards,
Yohan
