Summary of change:
Collecting some information to check VEMS ECU options '''Volvo T6 engine''' (B6284T inline6 cyl) with '''exhaust cam VVT''' ---- '''Ignition outputs / coils''' '''LS truck coils with built in igniters.''' * more exactly ? * pinout ? ** '''Active coil (need logic level outputs, or stepper outputs)''' ? *** yes LS7-9 coils are '''known good CNP coils''' with strengthy spark, '''logic level to control them''' ** or passive coils (need power IGBT output, in that case 8 IGBT would be best) ? NO, not passive https://www.jfetech.nl/epages/080402.sf/en_GB/?ObjectPath=/Shops/080402/Products/LS2-Coil i mean these coils. how i can find out that is it needed a stepper or logic level output from ecu? if i understand right these are active type coils. ---- '''Injectors''' * resistance ? * high-Z (>5.5 Ohm) ? ** 30V flyback is perfect in that case i use high-Z injectors. around 9-11ohm ---- I'm not sure what options/outputs etc I need. I drive mechanical operated throttlebody and mechanical adjusted boost control and i dont need any knock sensors or idle air controls. Everything else is mostly sure to me, but ... '''VVT control doubts me''' * VVT solenoid is closely like BMW vanos solenoid. only 1 solenoid with 2wire for camshaft. it controls oil flow to cam gear * simple '''low-side (NFET) outputs should be good''' (using free injector or ignition output) ** Min 2 IGBT would be recommended ---- '''ECU VEMS V3''' (v3/20423) * MAP connection: '''400kPa (6/4mm pneumatic)''' (so 180C PTFE tube can be used directly) * primary_trigger: '''HALL''' * secondary_trigger: '''HALL''' * ignition driver: '''2 IGBT''' * additional Low-side '''NFET outputs: 0''' (not needed) ** NOT needed, if 2 IGBT (or free injector outputs) * Knock input channels: 0 * Flyback: '''30V''' (not LowZ active flyback 8ch) * EGT input: * Hi-side PFET outputs: 0 * ETC BridgeOutput_Interface: 0 * withSDcard: removable * LCD connection: no Please carefully examine all options, including Flyback: 30V, manufactured as noted. See MembersPage/NikoVolvoT6/StartupInvestigation (2023 investigation) ---- '''Somewhat related''' * [https://en.wikipedia.org/wiki/List_of_Volvo_engines Volvo engines] * MembersPage/NitroX
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.
