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?
