Differential Fuel Burn question...

[hharney]

The test on the new JPI EDM 760 was flawless. I flew again today to record some numbers for the warranty card. Amazingly the fuel flows were very consistent with my factory fuel flow gauge. I have flown in other aircraft including Skymasters were the numbers were miles apart. Mine seem to be fairly close. Have others out there had similar results? The amount of information that this unit provides was rather intimidating while reading the handbook but once I started using it I could see that it was very simple to use. I haven't mastered the fuel quantity and usage yet but that will come.

Hope to get in a good cross country next week and have a chance to really see it work and to be able to dial it in at cruise. Should be a trip to Dayton to scout the hotel accommodations for SOAPA meeting. I'll post my results.

Congratulations on your new monitor.

Engine monitors are so valuable that I consider them a "Go--No-go" item for an IMC flight and I would prefer not to fly VMC without them.

The challenge is to learn how to interpret the data that they display. Gaining that understanding will save you a lot of money on maintenance and could, one day, save your life.

(some of the info in the manual concerning the interpretation of the data is factually incorrect--like what happens to the EGT and CHT during pre-ignition. Use the manual to learn how to operate the instrument. It is quite good for that. Be cautious of the materials related to interpreting the data.)
