And this meager info is all that I can find. Hm. Four coil firings equals two full revolutions of the crankshaft, if I remember correctly. So 1000 rpm would have 2000 sparks per minute, or 2000/60 = 33 Hz. That's nowhere near the two frequency ranges shown in the specs, so those specs have nothing to do with coil firings. Even if I forgot to carry a 1 or something. On Sun, 2011-05-01 at 11:21 -0700, mark drillock wrote: > I don't think so, based on the meager info provided.
