Mitsubishi EVO VI-VIII (if I'm not mistaken, the primtrig/sectrig trigger pattern is unchanged from evo 1 through 9). MembersPage/Minopp/EVOIXMivec

confirms EVO-9 has same trigger pattern.

Stock trigger system is supported (race rules don't allow to modify it and mitsubishi EVO-s are popular racecars): To choose this type of trigger, in http://www.vems.hu/vt/ primary trigger dialog page bottom choose the configlet "#Trigger settings for Mitsubishi Evo 6-7-8" (use same for EVO-9)

There are plenty of engines running with this trigger (however, smooth installs are usually not reported, only when installer needs help):

If ANYONE has sectrig and/or thirdtrig position measurements from VemsTune, please share (preferrably .vemslog file, but at least min-max values numerically. THANX)
