Summary of change:
'''I want to turbocharge my BMW 518i E28 M10 engine by using VEMS''' ---- '''Trigger secion''' ... describe the available trigger signals (links are OK too) * I still have some questions about the ignition setup possibility with my L-jetronic? ** I doubt that you would want to use the L-jetronic for ignition. The following (related to L-jetronic) might be useful: *** '''connector''' (if going with PlugAndPlay setup instead of Econoseal connectors). The econoseal-connector based install looks much cleaner (avoiding wire jungle, and less work), and generally recommended over the plug and pray way. *** '''wiring - whatiswhat'''. see PlugAndPlayJetronic, it saves some time with the wiring (not only for PlugAndPlay but for the econoseal install as well). Try to find other sources and measure yourself too for verification. *** trigger signal (from the engine, actually, not the L-jetronic) *** tables: OnlineCourse/AlienIgnitionLogging is theoretically possible, but requires more experience or experimentation than the rest of the install. I think better tables can be found faster from the web, maybe from others from MembersPage. '''Current plan for Ignition''' I keep the distributor, lock plate in the distributor and rotate so that the inductive pickup triggers 50-60° before TDC, remove vacuum hose. Q: Will this signal be controlled by an ignition IGBT and fire the coil by another ignition IGBT? A: The input from the distributor trigger is sent to trigger input #1 in the EC36 connector. The ECU then timing advance and fires the coil using one IGBT, also in the EC36 connector. ---- ITEMS TO BUY: * genboard v3.3 * injector FET 4x * WBO2 FET 1x * ignition IGBT 2x? * mapsensor 2.5 bar * idle stepper moter driver * econoseal PCB connector 36 + 18 * econoseal harness 36 + 18 * CNC case * LCD * tempsensors (are these only airtemp sensors?what about coolant temp sensor?) * WBO2 connector + sensor I recommend buying a pre-assembled Genboard to avoid this part of the project, but in case you feel confident with electronics and like the idea of saving some money - then go ahead. I would advice you to fully populate the board with as many fuel injector FETs and ignition IGBTs as you can afford - they can be used for a lot of other things and the minium I'd recommend is 6xFET + 5xIGBT. That allows you to run a direct-fire (distributorless) setup in the future.
