Bill,
Comments embedded below:
I should emphasize that the observations I
make are for only my EC2 which is set up for the 13B engine. A controller
set up for a piston engine with individual injectors for each cylinder would be
a different animal and probably incorporate a doubling of the pulse width with
the cold function and not have an injector backup mode. This is just a
guess on my part, though.

Hi Steve,
I assume you are getting your information from your
data logger which means that you know what is really happening as opposed to
what someone thinks will happen. So tell me this.
If I am flying in cruise at say, 8000 ft and 24”
of MAP, and I turn off the secondaries…What will happen?. I was above the staging point and all four
injectors were on. I turned two of them off. Will the primaries
continue to run at the same duty cycle, or will they attempt to double their
duty cycle up to the max of 100%? Above the staging point, if
you have the system wired with the double pole switch so turning off the secondaries
also engages the cold function, the engine will run with the primaries having
doubled their duty cycle (up to the maximum limit) In
other words, will the engine continue to produce the same or nearly the same
power as before I turned the secondaries off?? Yes
