readings?
I was thinking that I could use two injectors as primaries
and the other two as secondaries. I believe the secondaries kick in above a
certain throttle setting? If set up like that, wouldn't all 4 injectors
be working at cruise throttle settings? If so, if one injector failed,
there would still be one injector spraying fuel into one of the rotor
housings, and two spraying fuel into the other rotor housing, giving me some
kind of redundancy.
Hi Paul,
Just got my DSL and phone line back. I was
having withdrawals :-)
You're right about what you say, but I don't think
that half of your fuel will be much better than none. I'm guessing the
rotor would be so lean that it wouldn't fire
anyway.
With Tracy's unit, you can install disable switches
(and if you're smart you will when you're wiring the EC-2 <g>).
When you disable one set of injectors, the cpu knows it, and will take the
proper action, which is really a sweet feature.
If your in cruise, and all 4 injectors are running,
it will double the fuel pulse to the two injectors that you didn't
disable. That way, you will have normal fuel flow, up to the point where
your two injectors run out of flow. This will still get us into the high
cruise range, but maybe not WOT at sea level.
If you're at low throttle, and disable the ones that
weren't on anyway, nothing happens. If you're at low throttle and
disable the ones that were on, it turns the others on
instead.
Any of that makes
sense?
