Summary of change:
'''The car''' The project car is a BMW E30 325i with a 3.0 litre stroker engine with turbo. The stock Motronic system is not good enough for this engine, and it has been decided to install a Genboard. Many details will be the same as for the installation of MembersPage/GergelyLezsak. ---- '''Engine details''' Some of these things are still not decided upon: * Engine: M20B25 , 6 cyl inline, 12 Valves, SOHC. * Primary trigger: Stock 60-2 VR crank-trigger. * Ignition system: Single coil, mechanical distributor. * Idle control : Stock solenoid, two coils - only one used. ** I heard that both coils must be used, "A" powered to decrease opening and "B" used to increase it * Fuel injectors: Yet to be determined. * TPS: Yet to be determined. * IAT: Yet to be determined. * CLT: Stock coolant sensor has NTC curve 2.5kOhm@20C. (NTC's are normally rated at 25C ... not a big difference though) '''Issues''' * '''TPS''' needs to be converted to potentiometer-style for best result. Resistor network cold be hacked together to get three unique positions or a modern TPS could be mounted. * There is no stock '''IAT''' with the AFM gone. It could be custom made with a NTC thermistor (found in Webshop) or maybe a commercial GM/Delco IAT sensor ($16 at Summit Racing). * Fuel injection needs to be sorted out, this depends on keeping the stock harness or building new one which wires to separate injector drivers for each injector. ---- '''Genboard wishes and details''' Order'''ed''' an assembled unit and should be configured like: * Primary trigger : VR sensor / 60-2 wheel * Secondary trigger: Currently no cam sync, but prepare the board for Hall. * Low voltage flyback. * One channel EGT mounted. * knock is also mounted for most v3.3 (and all that is in stock at the moment) * stepper is usually mounted for assembled units (unless explicitely required otherwise, of course) Please note that order is apparently not checked out, it's among the "problematic orders". Please see if you can do something about it (check out). If you fail, for some reason, we can service it from there too. ---- *WikiAdvert: mailto:yourgo@sympatico.ca
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.
