primary patterns and secondary patterns have similar waveforms the difference being in the voltages.
from this screen we can get the height of the Firing KV which is how big a gap the spark has to jump(spark plug gap)
mirrors the spike that was created to jump across the spark plug gap.
Above is a video of the primary waveforms followed by Burn time graph.
Burn time measures how long the spark is flowing along the spark plug
Secondary Waveforms Clip. this test was perform with a spark tester plug installed on cylinder 3 lead.as you will notice the graph with for number three is higher indicating the higher output it has to fire the bigger gap
and heres thie KV bar graph
when accelerated, the graphs where higher and firing voltage was higher than at idle
