Summary of change:
= Mitsubishi 6G72 page = I'm about to install VEMS into a Mitsubishi Galant 2.5 V6 turbo, engine code 6G72 Trigger pattern is a bit unusual. Trigger wheel is like this: http://www.vems.hu/files/MembersPage/PeterJensen/mitsu/trigger.JPG It's very similar to the Lancer EVO trigger, but 6 cyls instead of 4. http://www.vems.hu/wiki/index.php?page=MembersPage%2FFero%2FMitsubishiEVO Apparently Peter Jensen had experience with this engine back in 2010, but now I cannot open his old triggerlogs, or interpret those configs with currently accesible VemsTune versions: http://www.vems.hu/files/MembersPage/PeterJensen/mitsu/ ---- '''Some hints to prepare?''' '''Scope and/or Bench-test''' with the following in mind: * start from VT primtrig dialog bottom, EVO configlet, key (verify after setting) is ** primtrig normal coil with sectrig subaruspecial = EVO 6-7-8 ** bit6 of: config_secondary_trigger & _BV(strig_subaruspecial) ... * sync condition: '''sectrig (falling) to primtrig (rising) time < 80/180 * period''' ** which is 80 deg for 4 cyl (where period is 180 crankdeg) ** 53 deg for 6cyl (where period is 120 crankdeg). Is that good or not for this 6 cyl trigger ? (if not, it's fairly easy to change or make it configurable) Proceed path: get '''scopeshot(s) or angular positions numerically''' * can be captured with VEMS configured to simple coiltype trigger + strobe if you know what you're doing ** but better scope, or get a free USB soundcard from Marcell and fry that (NOT your notebook's mic input :-). Mix the primtrig and sectrig with DIFFERENT amplitudes (because most USB soundcards have only 1 channel input; only output is stereo). ** timing is everything here: without precise info we cannot even make a good "signalgen" wav for audacity benchtesting (results are not valid if sectrig relative pos is different than real)
Optional: Add document to category:
Wiki formatting: * is Bullet list ** Bullet list subentry ... '''Bold''', ---- is horizontal ruler, <code> preformatted text... </code> See wiki editing HELP for tables and other formatting tips and tricks.
