I was wondering can you set up the fuel injection system for each rotor?

say one computer runs this set of injectors and another computer runs

the other set. sorta like splitting the motor in half if one side fails

you have the other right? Or is that how we do it now? And, how about

using the fuel injected motorcycle carbs the Suzuki Hayabusa is

180hp with injection but they use butterfly valves not sliders.

One rotor on a two rotor is not enough.

The big problem with high pressure EFI is the high pressure plumbing,
the return plumbing and the current consumption of the high pressure
pumps when the electrical system goes south. The computers are rarely
the problem. The injectors are known to fail from time to time as well.
Airplanes sit around for months at a time, sometimes outside, so
the operating environment is different than that for a car.

Also the EFI plumbing and wiring design and construction must be
done right and the average home builder is not up to it.

The problems with aircraft carbs are over stated. Aircraft engines
with carbs are much more reliable than aircraft engines with fuel injection.
The high pressure pump is frequently the problem. I had one fail
in a Mooney I was flying. Carb heat is no big deal. I have flown
many hours in carb equipped airplanes with only one carb failure.
A sunk float. Turns out there was an AD on it not accomplished.
