I am thinking that perhaps the Constant Speed Controller could take a pickup off the Crank Position Sensor for tach sensing as well. It doesnt need to be a strong signal.. just a signal. Just a thought. The Crankshaft positions sensor will give a reading regardless of injector disable or coil disable settings.

Run it by him and see what he thinks...

I am not up to speed yet on the EC2, but aren't we really saying that injector pulsing is one time per rev per rotor ?  And how would Mark Burton's constant speed controller react if the EC2 was switched to injector disable mode.  Depending on how it was wired, it might suddenly sense zero power or 2X power.  Just thinking out loud.

Tracy and Ed,
   Thanks for the info......I am talking to the producer of a
constant speed prop controller for my "IVO" and he needed to
know how many injector pulses per revolution.....Uses it as a
signal for the power percentage function of his controller....
Like I need to duplicate one of my EM2 functions !!

Hi Kelly,

I've been over this with Tracy several times and the answer is always "ONE  time
per rev" {:>).  The reason I ask the question is that for my EFI fuel monitor to
give the right answer, I have to set a constant for the injectors flow rate that
is twice the rate flow Mazda claims.  But, if the injectors did pulse twice per
rev then the stated injector flow rate would suffice.

However, no matter how many times I ask Tracy,  he stubbornly keeps insisting
"only once per rev" {:>)

    Tracy,
        Do I have this correct ? The EC2 batch fires the injectors therefore all
the injectors (if above
    stageing MAP) pulse twice per eccentric shaft revolution.........Inquiring
minds want to know !!


    Thanks
