I am planning on the Z-14 system in my RV-10. I have dual alternators, dual batteries, electronic ignition, and electronic fuel injection (Dual EFII System).

Looking at the schematic, it appears that ECU 1 / Fuel Pump 1 would be on the main battery bus and ECU 2 / Fuel Pump 2 would be on the aux battery bus.

This arrangement means power is always available to those items, even when the battery masters are OFF.

I am planning on fuel pump ON/OFF switches and could also switch the individual ECU power lines.

Anyone (maybe Bob?) care to weigh in on this arrangement?

Thanks!

I am using the same configuration with each of the two power buses on guarded switches and powering only the ECI and Fuel Pumps.  My original configuration was using the FADEC system but have replaced with the Dual FlyEfii system.

That's the idea. Electrically dependent engine
accessories driven from battery busses are avaiable
even when the electrical system(s) are shut down . . .
as in case of smoke in the cockpit. The only
operational concerns to explore are potential
difficulties if BOTH primary and secondary
accessories are energized at the same time.

Had a Z-14 builder some years back with dual
ECU's sthat would argue with each other if
energized at the same time. We arranged for a
little lockout mechanism that prevented a
BOTH on at the same time. There was no hazard
for having other dual accessories energized
at the same time.

We machined the lock out of a piece of 1/2"
aluminum. It mounted between the two ECU
switches on a single screw.
