Reading the HDX installation manual, I came across this:
Is this still true? If so, it's kinda nuts. If the fuel computer can use the compensated pulses/gallon value to calculate the correct Total Fuel Used, why not use the compensated value in the displayed Fuel Flow widget? Also, which value does the HDX use to calculate "fuel remaining at destination"? The uncorrected fuel flow, or the compensated value?
Once verified and saved, the actual, normalized, corrected Fuel Flow value should be used everywhere, including pilot-facing widgets.
If you have not installed physical fuel flow sensors, the fuel flow information from 912 iS ECU used by the SkyView Fuel Computer can be adjusted if necessary: SETUP MENU > HARDWARE CALIBRATION > EMS CALIBRATION > FUEL FLOW CALIBRATION > PUL/GAL (C37 P14) > (value). The default value is 68000. Higher numbers will reduce reported fuel flow; lower numbers will increase reported fuel flow. For example, if the reported fuel flow is 10% low (determined by careful records of fuel fills and fuel used), set the value of C37 P14 to 61818 (68000 – 10%). Changing this value will not alter the displayed fuel flow; it will only alter the fuel used calculated by the SkyView Fuel Computer.
