Summary of change:
We're investigating an engine setup First we would want to confirm that trigger is 48+1 (unmodified LS1 with 24 tooth on crank without missing tooth), as on: * MembersPage/JorgenKarlsson/TwentyFourX * MembersPage/EmilLarsson/LsMustang '''Pri and sec trig setup''' * Both pri and sec trig edge are "Falling". Regular "coil type" with "LS1 forgiving" enabled for sec trig. * Pri trig is (must be) falling edge to get evenly spaced teeth. ---- '''Triggerlog with simple coil-type''' * Trigger setup as "trigger type = coil type" and "special trigger = normal" (no divbyN). * '''Startup attempt will be made with this setup'''. It seems to sync well during cranking. First must setup a strobe light. *[http://www.vems.hu/files/MembersPage/MattiasSandgren/LS1/cranking-normal-48.triggerlog triggerlog] and [http://www.vems.hu/files/MembersPage/MattiasSandgren/LS1/cranking-normal-48.vemscfg config] http://www.vems.hu/files/MembersPage/MattiasSandgren/LS1/cranking-normal-48.png ---- '''Triggerlog with divbyN = 2''' * Trigger setup as "trigger type = coil type" and "divbyN = 2". * This has historically worked out fine on several engines, so the trigger configuration was not under scrutiny. Triggerlogs and vemslog with engine running and having issues. Examples of cranking and idle, with "LS1 forgiving" both dis- and enabled. * http://www.vems.hu/files/MembersPage/MattiasSandgren/LS1/ Note about triggerlog capture below: auditrigger divby2 so the missing tooth might be "optical illusion" : http://vems.hu/files/MembersPage/JorgenKarlsson/LS1/MattiasChevy/ls1_23_1_strange.png ----
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.
