22+ hours into my flight test period and my fuel flow sensor is still reading high (GRT EFIS w/ EIS 4000). It consistently reads over 10.5-11 gph in cruise on an IO-360. Been keeping track of my "ins and outs" as far as fuel goes. Looks like it's reading about 17% high. Sometimes I see 16 gph like on climbout.
Is there a way to correct it? I'm sure there's an AuxSF and AuxOFF - the documentation says GRT calibrates it. But just wondering if anyone else has had this problem and what the fix was.
My fuel level senders are doing pretty good. No more than about 0.5 gal off at each fillup. So I'm relying on these because my FF numbers tell me I need gas a lot sooner!
I placed the sensor in the same place I've seen it on other RV's, in the cockpit just beyond the boost pump with plenty of "straight" line on both sides.
