Really? That's very interesting. You're saying if you're too far off, it won't pulse at all? What do you mean "maximize the dwell angle"? Shoot for the highest reading I can get? Also, for anyone reading: I am using an analog dwell meter with a 6 cyl scale, and a 8 cyl scale. The meter says to double readings on the 8 cyl scale if reading a 4 cyl engine. -Supposedly-, someone from this list says NOT to use the 6-cyl scale. Am I supposed to use the 8 cyl scale and read it as-is, or double the reading? Or what?
