Thanks for the explanation, Rusty. I = hadn't=20 considered that after one injector failed, the one remaining injector = would=20 probably not supply sufficient fuel and it would go lean anyway. = There's a=20 lot ot great information available on this forum. Thanks again. I = emailed=20 the single rotor Ebay guy and told him that I would pay 20% more than = your=20 highest offer. (kidding). My new fiberglass nose gear strut = arrived today,=20 so hopefully I will be able to install it tomorrow and do some more=20 flying. Take care. Paul Conner

I was thinking that I could use two injectors as = primaries=20 and the other two as secondaries. I believe the secondaries kick in = above a=20 certain throttle setting? If set up like that, wouldn't all 4 = injectors=20 be working at cruise throttle settings? If so, if one injector = failed,=20 there would still be one injector spraying fuel into one of the rotor=20 housings, and two spraying fuel into the other rotor housing, giving = me some=20 kind of redundancy.

Hi Paul,

Just got my DSL and phone line back. = I was=20 having withdrawals :-)

You're right about what you say, but I = don't think=20 that half of your fuel will be much better than none. I'm = guessing the=20 rotor would be so lean that it wouldn't fire=20 anyway.

With Tracy's unit, you can install disable = switches=20 (and if you're smart you will when you're wiring the EC-2 = <g>). =20 When you disable one set of injectors, the cpu knows it, and will take = the=20 proper action, which is really a sweet feature.=20

If your in cruise, and all 4 injectors are = running,=20 it will double the fuel pulse to the two injectors that you didn't=20 disable. That way, you will have normal fuel flow, up to the = point where=20 your two injectors run out of flow. This will still get us into = the high=20 cruise range, but maybe not WOT at sea level. =20

If you're at low throttle, and disable the = ones that=20 weren't on anyway, nothing happens. If you're at low throttle = and=20 disable the ones that were on, it turns the others on=20 instead.

Any of that makes=20 sense?
