Summary of change:
What we have at the moment is: BMW 325iX with stock M20B25 (inline 6 cyl) engine planned to be turbocharged, but before it the GenBoard v3.x should take its place on the car. As I am not an electronics expert, any help from others who have successfuly managed to install Genboard on their cars will be appreciated! As we have a spare engine, while studying / installing Genboard these changes will be made on it and later it will be installed on the car in the place of the stock engine: * larger 440cc low impedance injectors (available at the moment); * head porting, slight combustion chamber changes; * custom inlet, outlet manifolds; * lighter valve retainers, rods, flywheel etc.; * turbocharger; * ignition: '''got COPs from M52 (Bremi 11860)''' '''Q: What parameters of coils are neccessary to know (resistance etc.)? Or is it enough?''' [MembersPage/PhatBob] How many connections do the wires have? Can you get hold of the wiring schematic for the installation that has these coils as this makes working out the connection a hell of a lot easier. I guess this is what you mean: [http://photobucket.com/albums/a97/crushcars/Turbo%20project/?action=view&current=M52_electrical.jpg wiring] [http://photobucket.com/albums/a97/crushcars/Turbo%20project/?action=view&current=COP1.jpg coil_1] [http://photobucket.com/albums/a97/crushcars/Turbo%20project/?action=view&current=COP2.jpg coil_2] [http://photobucket.com/albums/a97/crushcars/Turbo%20project/?action=view&current=COP3.jpg coil_3] Resistance measured: primary coil: 0.7 Ohm; secondary: 7 kOhm. There are 3 connections on each COP. Weight ? These look like very standard transformers. If they are good for inductive ignition app, GenBoard can drive them. If they are for CDI only (inductivity should be measured to know, if their datasheet is not available. Or experiment from 800 us dwell, and measure spark energy, see DummyIgnition, DwellControlIgnition). Got specification for 11860T, that should be very similar to 11860: [http://photobucket.com/albums/a97/crushcars/Turbo%20project/?action=view&current=data_sheet.jpg Data sheet]. '''Comments?''' ---- Shopping cart: * 1 x Assembled v3.3 controller ** ignition driver: 6+2; (this means 6 power outputs, 3 or 6 of which you apparently plan to use; and 2 logic-level - these will be unused) **Knock and EGT: yes; **LCD and PS2: no; **MAP connection: 250kPa onboard; **primary_trigger: VR; **secondary_trigger: HALL input should be fine, usually not used for this engine *1 x EC36-harness *1 x EC18-harness *1 x Wideband O2 sensor ** 1 x WBO2 connector * 1 x EGT sensor would come handy '''Q: What else is needed?''' ---- '''Links to similar engines''' * MembersPage/GergelyLezsak * MembersPage/BengtR * search for BMW on SiteIndex
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.
