Hi Steve

I concur with Finn on this issue. there is enough difference = ;between aircraft brands that all pilots need to be checked out & profi= cient in specific functions before taking command.
If your pilot friends were going from piston to turbine they woul= d not expect to operate them the same way, and as such need to learn t= he peculiarities. going piston to efi rotary is no different.

Here's my opinions:

No one should be flying an EC2/3 equipped airplane without being f= ully=20
trained on their functioning and installation. Without that, they = would=20
have no chance of in-flight trouble shooting. What to do if an inj= ector=20
clogs? What to do if a coil fails? and so on.

Having extra mixture range is a feature, not a liability. Say your= fuel=20
pump goes weak or filter starts clogging, pressure regulator goes = bad or=20
fuel pressure otherwise starts dropping.

Having to rely on a gut reaction of blindly turning the knob all r= ich=20
without listening to the engine would disqualify the pilot from fl= ying=20
that airplane.

Having said all that, should be no harm in experimenting with Mode= 2.=20
You can always reset it:

If you have an EM3 engine monitor, you can check the setting of th= is=20
parameter on the engine info page by holding the Acknowledge butto= n=20
(button 4)  and then pressing UP (button 1).  The dynami= c range=20
parameter is the 6th (next to last)  number on line 4.  = The value is=20
displayed in hexadecimal format.
Resetting Injection dynamic range  to factory default setting
1. Turn the EC3 power off.
2. Select mode 2 on the Mode Select switch.
3. Press and hold the Program Store switch.
4. While holding down the Program Store switch, turn on the power = switch=20
to the EC3.
5. Keep holding the Program Store switch for about 1 second and th= en=20
release it.
6. ... will now be restored to factory settings and you can begin= =20
programming after starting the engine.
7. Return the Mode Select switch to 0.

Check your EC2 manual.

Finn
