Hi Tracy,

A feature I would like to see would be the ability to set up a screen
with user selected items displayed.  I think it was doable on the EC2,
but it was a "factory" setting.

I would also like to see an optional pulse rate input for TAS bypassing
airspeed, temp, altitude inputs.  OK, it's for use in a car, so I'm
probably the only one that would be interested!  Can the EC2 be
modified for such an input?

Bob W.
