Dwell and HEI's

[bruce plecan]

Me thinks I might be able to shed a glimmer of light on something.
After looking reading this thread, the coil is "on" for a time 
determined by a R/C timer, so the dwell looks to change as the
rpm do, well ya, but the coil on time is the same it the matter of
how many crank shaft degrees occur during this time that gives
the illusion that something has changed.  
Bruce   Murphys law may have started in 1949, with a rocket 
            sled pilot, who made a run only to find out all the 
            sensors were hooked up backward,  Geeeeez
