[Diy_efi] OT - cap/rotor clearance

[dh at busb.com]

Okay, I'm baited.


The rise time is dependent on the electronics and nothing else.  The timing
is dependent on the rise time and nothing else.   One degree of roation at
10,000 RPM is

1/10000 * 60sec per min  / 360 degrees per rev  =  0.016 milliseconds

16 microseconds and the rise time of the pulse is on the order of
KV/microseconds so the timing delay would certainly be less than one degree
of revolution at any reasonable engine speed.
