Found this on the net sorry dont remember where
An engine at 6000 RPM has 100 Trigger pulses per second so the flywheel turns 360 degrees in 1/100th of a second so to change the timing one degree we will only have to delay the trigger pulse by 1/3600th of a second. Is this math right i think it should be 1/36000th of a second ie. (.027ms)/ degree of timing at 6000RPM.
Am I missing something?
