Summary of change:
Placeholder until I figure out how this works a bit better. Planning on converting my N/A BMW 87 325is to VEMS. Purchased the parts early December. Hope to have working system sometime mid Jan 2006. Similar engines: maybe a page could be created for the 6cyl club ? * MembersPage/GergelyLezsak * MembersPage/BengtR * MembersPage/MattiasSandgren * MembersPage/FredrikEriksson There is about 15 more "BMW" on MembersPage, but many I know are in early phase of the install. 12/28/2005 Finally received all the VEMS stuff I ordered: 1 x Wideband O2 sensor 1 x Hall Sensor - Unipolar 1 x Temperature sensor 1 x Wideband connector - With wire: with crimped wires 1 x 250kPa MAP sensor - Model: MPX4250AP 1 x Assembled v3.3 controller - primary_trigger: VR - secondary_trigger: HALL - PowerFlyback: yes - ignition driver: 6+2 - Knock and EGT: yes - LCD and PS2: yes - MAP connection: offboard(electronic) 1 x LCD4x20 - Color: green 1 x Econoseal36-harness 1 x Econoseal18-harness In the past couple days I mapped out most of my basic wiring, and the BMW stock wiring. I am planning on making a harness to link into existing sensors. I am then going to have a 2nd harness for all the new stuff I will need. The main reason for this is so I can return the car to stock computer if needed. Think this is the safest plan for my 1st setup. Even if it might make things a bit more complex then required on the wiring part of things. Tonight I made up my DB9 cable to the computer and DB9 to LCD. Question: What is the bare minimum I need to hook up in order to connect to the computer and not fry the board? I figure all the grounds and power. But do I need to hookup the injectors and flyback, even if I don't have injectors or plan to test those outputs? I really just want to test that my LCD is wired up right, get the contrast and such.
