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

Greetings,

I guess this is mostly to Tracy, unless someone else knows. What's the official designation of the input shaft on the RD-1C drives? I presume it's known as a (some number) spline (some size) diameter, or someting like that. Is it the same as what was used on any particular vehicle?

I've seen some dampeners available commercially, but I need to know which one would fit the input shaft.  I'm looking into getting an X-ACT Streetlite flywheel as a test as well. It's about 11.5 lbs, and uses the auto counterweight. I'll be doing some measuring today, while I'm out at the hanger moving tools and such back to the garage for RV-8 construction.

Thanks,

Rusty (shut up Thomas <g>)
