I had the black box recording going and it looks like it just died within about 20 seconds - went down all the way from 11 gallons ( which is btw wildly inaccurate for my Rotax 912 ULS but that's beside the point - as I mentioned I have not had chance to calibrate it yet)
I was doing touch and goes and on increasing power to 5300 RPM ( the go part ) it went up to 11 gallons and then went down to 0 within 20 seconds and never recovered ( the csv file is attached )
Here is the relevant part - fuel flow and RPM - you can see RPM being constant at 5300 or so while fuel flow dropping to 0.
Reading the troubleshooting guide for IES, to me it suggest a blocked fuel flow sensor rather than anything else but I am not sure - should I even bother checking electrical connections or does it sound like blockage problem ?
