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

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?
