Changes by last author:

Changed:
* Trigger settings for, 12+1extrapulse crank 4+extrapulse on cam 4cyl Honda K20A engine camsync
* Trigger settings for, [12+1extrapulse crank 4+extrapulse on cam] 4cyl Honda K20A engine camsync. 1.2.41 fw recommended
Added:
** please note that clearance is only 2 degrees at some sectrig to primtrig transition (way lower than the 10..15 crankdeg for any normal trigger pattern), so nissan type (higher frequency, not as great noise tolerancy) sectrig input might be needed for this pattern; Luckily the interesting transitions are more than 5 crankdeg apart, so no problem experienced in practice.
Added:
* in 2018, syncup mods were requested, separate implementation for cam_check_pol

** originally high-rev benchtested with busyloop stim benchmark.c L336 (primtrig was wired from inverted fetdriver output, not injector output ?)

** similar: /svn/firmware/utilities/testing/rigol to write rigol DG1032Z signalgen compatible csv file
