Ok, Mark. I can see you will continue until I fess
up {:>).
Yes, I seem to find them all. I (and several
others) frequently fly with mode 1 selected to have it handy should we
decide to fine tune our fuel map. I was attending the Rotary Round up when
we decided to compare the sound of my two rotor and Tracy's 3 rotor. So I
hopped in my airplane and threw all the switches on and pressed the store button
to get a squirt of fuel into the intake (forgetting it was in mode 1) to prime
the engine
For those of you without any EC2 experience, if
mode zero is selected , pressing the program store button causes the
injectors to click on momentarily and squirt some gasoline into the
manifold. Makes a nice priming function. However, with mode 1
selected (with the engine not running) pushing the store button causes the
injector simulator to fire the injector continuously as if the engine was
running at 3000 rpm!!!
Picture all 4 injectors clicking madly with my two fuel
pumps pushing all the gasoline they want through them into the combustion
chamber. Can you say instantly flooded to the max? Can you say
way too much fuel!! Like out the tail pipe fuel!! Like don't light a
match! too much fuel.
So as several have mentioned - keep a fire bottle handy
when ever starting or otherwise messing around with fuel. Also, make
certain you are not in Mode 1 when "priming" the engine {:>)

Chime in here whenever you wish, Ed.
What I'm referring to is at the last RWS fly-in Ed went to start his
engine in the morning and pressed the Store (primer) button and didn't see
that the EC-2 was in mode 9. He had the fuel pump(s) on and when he hit
the Store button it went into injector simulation mode which caused
the engine to flood and fuel to pour out the exhaust. When something
like that happens, one spark and you've got a very bad situation. Always
have a fire extinguisher (or two) nearby.

Good luck.

One of my 'good
practice' recommendations:
The last thing
you do before hitting the "Start" button is turn on the EFI fuel
pump.
The first thing
you do when shutting down is turn off the fuel pump.
