     Paul,
     I just can't seem to leave this alone.  How about adding the following
     parameters to the selection list:  (this includes all the parameters
     listed by others up to this point)
     1.  RPM
     2.  EGT x 2  (one for each rotor)

Now we are getting expensive. That means signal conditioning for thermal
couples which adds a lot to the cost. If Tracy ever decides to add EGT/CHT
to the EFI computer than it becomes very doable.
 
     3.  Voltage

This might be possible. If we go with a processor with built in A to D converter.

     4.  Hobbs time

Hobbs time means we need  non-volatile read write memory. That too may be possible
I will have to check the features of the processors available. Flight time would be
very little trouble.

     5.  MAP
     6.  O2 (fuel-air ratio)
     7.  Fuel Flow
     8.  HP Output

You would need a torque sensor and again an A to D converter.

     9.  Temps (list all possible parameters)

See the EGT/CHT message above.

     10. PGM (current setting of the programming knob)
     11. Mixture (current setting of the mixture knob)
     12. Data Table in use
     13. Staging Flag
     14. MPG
     15. Endurance

This assume you somehow tell the computer how much fuel you took off with.

No comment means we have that capability now.
