I have now flown with the EIS 4000 about 80 or so hours and really like it but am ready to modify at least one programmable page. Currently I am using one like this:
The display shows:
Tach, Fuel Flow, Amps across the top
Oil Temp/Oil Pressure, MP, Volts across the bottom
Amps and Volts are now very boring to look at! I thought it would be useful but unless something fails, it's pretty useless. If either volts or amps go haywire I will get an alarm, so they don't need to be on the display.
MP and Tach are useful during transients but pretty worthless once established in the cruise. Because I was retrofiting this on an engine and had an interference problem with the engine mount that prevented me from changing oil temperature sensors I monitor OT on a separate gauge, so I don't need that on my display either.
What I find myself wanting to see is this:
With:
Highest CHT, Highest EGT, Highest EGT Drop, Oil Pressure on the top
Fuel Pressure/Fuel Flow and Endurance in HH:MM on the bottom
My thinking is I am finding out that fuel flow can change a little, especially when chaning tanks, and with hot weather and a hot engine fuel pressure can change a bit especially when descending and heat soaking the fuel during low fuel flow. Fuel flow can affect CHT and EGT and degrees ROP or LOP.
In short, the parameters on the second screen shot are the ones that can change without my knowing it and can effect performance and engine life and range. At a glance I can see what is going on.
What programable pages have the other learned practioners of aviation who come to this forum found useful? I know a lot of people have EMS displays on the EFIS that make this a moot point, but that expense has to wait for my finances to recover, so I need to make the most out of my EIS unit.
BTW these screen shots were taken from "Mike's EIS4000 Editor" at http://www.my9a.com/eis/ and then trimmed and converted to jpgs using Paint. My thanks to Mike for providing this little GEM. It makes it easy to generate the bits of letters and numbers for programing the EIS custom pages.
