Sounds Great, Tracy. Appears you have covered
the most significant features already.
1. Lets see - how about a coolant/oil
temperature hold - in otherwords say for a long climb modulate the rpm/manifold
to see that coolant/oil temps are not exceeded by what ever you set, but
otherwise pedal to the metal for a maximum best rate of climb short of
melt-down.
2. How about tying it into your airspeed
sensor to maintain a constant airspeed or could set in your Vne limits {:>)
or maximum descent airspeed.
3. In fact, How about setting up so you
can program in the parameters for certain flight regimes such as
might could factor in such
things as density altitude or certainly OAT, perhaps even have a "Light" and
"Heavy" mode adjust these factors for aircraft gross weight.
a. Take off and initial
Climbout
b. Cruise climb
c. Best economy cruise
d. Best Speed/economy combination
(optimum best of both)
e. Descent
f. Eating your inflight
snack
'bout all the hair brain ideas I can think of at
the moment. I am sure you will get more from others.
4. What happens if power to the unit fails??
What default mode does it have - simply stays where power left it? Goes wide
open (not likely in an automobile application).
Tell us more
Best Regards
Ed

controller
The FBW RX-8 throttle body controller design is done and the
inevitable 'feature creep' has begun.
It occurred to me that since the throttle controller has
access to all the EC2 data that it could do a number of things. The two
I have adopted so far are manifold pressure hold and RPM hold.
They hold the respective parameter constant at the value it was at when
the function was engaged. Obviously the MP hold can only work up to the
ambient or turbo boost pressure available. They are disengaged by either
hitting the cancel button or sensing that the pilot is frantically trying to
regain control by moving the power lever.
Any other ideas for this widget before I freeze the design?
