Adam -

We went through a long convoluted period of time planning to install an   
IOF-550 (FADEC) on our ES. Is your engine a new one from the factory?  If  
it is, then everything is there to go with the FADEC mod (sump, crankcase  
gear, et al.). You won't need much of a kit, if any.  I believe that for  
the last year and a half, they have been doing this on all of their  
IO-550's.

The problem has been the software and more specifically the idle  
speed/performance of the IO-550. It has something to do with the mass of  
the prop, but that is not the only cause IMHO.

They have been slipping the release of that engine for about 2 years. This  
track record raised our doubts.But we ran out of time and switched to a  
straight IO-550N2B. Had to redesign the electrical system and the panel!!  
GAMI's PRISM is now back in the decision tree. If Continental's FADEC  
starts getting better field data (a decent installed base from which to  
get that data) it may be competetive.

Hope this helps,

John
