Pattern 2
The second pattern is similar to the first but instead of having different size trigger windows
for each cylinder it has pairs of trigger windows matching the two cylinders that are
approaching TDC together on opposite strokes (i.e. compression-combustion and exhaust-
induction). The first pair is not a true pair; the two windows differ by a number of home
pulses in size, all successive pairs are identical in trigger window size so a 4-cylinder engine
has one odd pair and one true pair.
