Summary of change:
My project is to turbocharge a BMW E30 325i M20 engine. Engine specs: * cyl count=6 * main trigger= 60-2 on crank http://www.vems.hu/wiki/index.php?page=MembersPage%2FGergelyLezsak%2FTrigger * stock internals * T3/T4 turbo 50 A/R Compressor, 0.63 A/R Turbine .57 Trim 3" inlet stage 3 wheel * Oil cooling on pistons http://www.e30tech.com/forum/viewtopic.php?t=5223 * Intercooler will be as big as possible * Lime green 440 cc bosch high imp petrol injectors I guess we have a lot in common: http://www.vems.hu/wiki/index.php?page=MembersPage%2FGergelyLezsak ---- [\ MembersPage/JanSaenen/LPG LPG Section] [\ MembersPage/JanSaenen/Links Links] ---- read: original MegaSquirt documentation besides VEMS manual, since MegaSquirt is basically the same. [http://vems.sourceforge.net/manualhtml2/ GenBoard Version User's Manual] http://www.vems.hu/wiki/index.php?page=GenBoard ---- Assembled v3.3 controller * ignition driver 6+2 * Knock and EGT yes * LCD and PS2 yes * MAP connection offboard(electronic) * primary_trigger VR * secondary_trigger HALL * Bosch sensor: http://www.geocities.com/tech4tdi/pages/map.html IAT sensor: GenBoard/Manual/IntakeAirTemperature ---- '''Spark control''' With your stock 60-2 wheel you can control a wasted spark coilpack directly with VEMS without any additional triggers. You can borrow a coilpack for a 6 cylinder car from an EDIS6 equipped car, like a Ford V6 (You don't need the EDIS module itself, just the coilpack!). Laptop connection: Basically you use the serial port on the computer, and the corresponding port on the Genboard is either through the smaller EC18 connector or from a pin header inside on the board, which is usually routed to an end-plate in the form of a regular DB9 (standard serial RS323) connector. ---- '''links''' BMW on LPG: http://zymo.homemail.com.au/bmw2.htm More info on nitrous systems: http://www.diy-nitrous.fsnet.co.uk/index.htm ---- VEMS GenBoard/VerThree (v3.x, like v3.3) has 8 output channels that are capable to drive low impendence injectors.
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.
