I have an ECi XIO-360 fuel injected with the Airmotive Engineering (AE) fuel pump. The AE tech sheet says that at idle of 750 rpm the fuel pressure should be about 6-8 psig. I have idle set at 750 and get a 50 RPM rise with the mixture lever before cutoff. ECi cautions against using shipboard sensors to set fuel pressure, as I suppose they don't believe them accurate.
As that is all I have right now I thought I would ballpark it. I turned the low pressure relief adjustment 4 turns CCW and dropped the Dynon displayed fuel pressure from 13.6 to 11.6 (that's at idle). As I don't think I have four or more turns available to me I figure I better get a "precision" fuel pressure gauge.
ECi would be happy to provide me one for over $700!!! Yikes. What does everyone else do? Any loaners out there?
Suggestions??
