EFI fuel pump, injectors & ignition can consume up to about 20 Amps.

The

EC2 controller itself uses about 1/4 amp.  That better be a hell of a

small

backup battery to last 5 hours!  Of course I  know very little about

their

system so they may be using a low pressure fuel injection which could

reduce

the electrical requirements a lot.   I *would*  like to know how they
achieve "full redundancy" though.  Do they really have two injectors per
cylinder (or is it throttle body injection?)  Full Authority  also

implies

that a servo operates the throttle.  If not, this is not a true FADEC

system

as so many falsely claim to be.  The short blurb I read on this system
indicated that it was installed on an engine using the original

carburetor

as a throttle body and had the original throttle linkage.  Because of

this I

wrote it all off as marketing hype.

I can only relate to this system based on my interview
and observation. The carburator is gutted and only acts
as an air throttle. This obviously keeps cost down so
that the induction system does not require redesign.
The injectors are placed on the cylinders.
As an update, the system is perhaps only weeks away
from certification.
I believe this is the reason why Continental paid such
a price for the company.(to obtain this system).
