How do they handle the backup electrical system?

 Small backup battery, about motorcycle size, that will
run everything, including basic radio for about 5 hrs.
A small annunciator panel visually monitors all systems.

Tracy how much current does your system require?

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.
