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] MembersPage/IrbensA/Wiring ---- 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:
