Tracy or anyone,
Can you tell me what sensors you use to
calculate fuel ratios.
I notice the mention of a MAP sensor (vacuum type),
but that would give pressure, not density.
I notice the absence of an oxygen sensor in the
case of 100LL is used - this is understood. I suppose an oxygen sensor could be
used independently.
I assume RPM would be in the calculations for fuel
flow, but I wonder how you actually arrive at air density? perhaps OAT is
used.
Basically I wondering what the simplest air density
sensor arrangement would be. I thought Oxygen sensor (not for 100LL), with a RPM
and throttle position sensor.

Old
time distributors and carburetors didn’t care how badly you wired the
electrical system. Digital systems are not so forgiving of
poor wiring practices. Noisy power or ground wiring is one
of the most common causes of initial builder problems with computerized
equipment (including ECUs).
In addition to the wire
bundling answers you got, the basic power wiring is as or even more
important. Here is a basic aircraft wiring scheme that I recommend in
latest version of the installation guide. Not detailed but somewhere to
start. Note the independent power feeds from the battery for the various
systems. This is a physical as well as electrical representation.
