Quick note for future readers.. The aircraft app takes advantage of the Megajolt's ability to store two complete ignition configurations, as the optimum ignition timing for best power mixture (150~100 rich of peak EGT) and best economy mixture (lean side of peak EGT) is quite different. For best per...

Follow up to previous posts. I've flown an EDIS/Megajolt system about 100 hours, in combination with one Slick mag. I'm installing the second system now, which will eliminate the Slick. Slick or Bendix (now Continental) mags work pretty well given best power conditions. With a single EI on an IO-390...

Hmm...I'm curious. What did you set for cranking?

I assume you can set crank timing ATDC if you wish.

Steve, that is a GRT Sport, 8.4 screen, early 2010 vintage. At the time an upgraded processor was an option. Now it's standard, along with internal autopilot functions and a WAAS GPS. I did not get synthetic vision, new at the time, but GRT is really good about upgrades. GRT refers to the Sport as t...

Great minds and all that rot...one map fixed, one map dynamic is what I was thinking. Very pleased to hear of the fuel flow reduction. I love the 390, but this is typical fast cruise and fuel flow: Mixture is near peak power (EGT ~100 ROP), 10.4 GPH, 185 knots true. I'd give up some speed for fuel s...

Yes, I'm very pleased with GRT. The EIS is mounted front and center as a dedicated fuel totalizer. All its other data is displayed on the EFIS via serial line.

The drawing tool is just an old version of AutoCad.

Did you notice any operational improvement with EI on the O-200?

Thank you Steve. Those amp numbers are excellent. I figured you had them, given the regulatory requirements in your part of the world. Did you get an approval? Anything I can do for you on this side of the pond? The GRT EIS has two tach inputs. When it detects no signal on #1, it will display #2. Ma...

Brent, Steve, Peter,

Anyone know the average system (MJ/E + coil pack + EDIS module) power draw at some stated RPM?

Likewise, power draw for the MJ/E alone, and for the Ford side of the system?
