First time poster here. I have a new IFD 540 installed with the EI 30 Combo engine analyzer. I love them, they are amazing.
I’m wondering how to reset the fuel total on the IFD 540 when I refuel?
The EI registers full tanks but that doesn’t feed to the 540. Thanks, Pete |

I'm not familiar with the EI devices, but you might want to recheck the config settings on both the EI and the IFD. I have a JPI EDM incl FF, and when I set the new total after refuelling it appears automatically on the IFD. But the wiring and config needs to be correct on both. ------------- Vince |

| The fuel data should be passed from the EI device to the IFD. I have this exact same setup (EI CGR30P feeding an IFD540) and get fuel and range data shown both on the CGR and the IFD. |

I have an EI FP-5L connected to an IFD540 in my plane. Whenever I reset the fuel level in the FP-5L, the IFD reflects whatever the FP-5L thinks is in the plane. I don't think I can do anything in the IFD to affect its readings coming from the fuel flow instrument. Those readings are maintained by the fuel flow instrument and passed to the IFD.

I also have the same setup: CGR30P/IFD540/fuel flow meter with no connection to fuel level transmitters in the fuel tanks. The CGR receives raw pulses from the fuel flow meter. The flow meter sends a pulse with the passing of each “x” gallons (x is a very small number). Using the K factor (configured in the CGR30P), the CGR30P calculates (‘totalizes’) the quantity of fuel passed through the fuel flow meter. It subtracts that totalized value from a total fuel value to calculate a Fuel Remaining value. Whenever fuel is added, I must change the value in the CGR30P so that its a Fuel Remaining value is accurate. The data is sent from the CGR30P to the IFD540. From the IFD540’s perspective, it is ‘read-only’, meaning that the values cannot be modified on the IFD540 and sent back to the CGR30P.
