Summary of change:
Just starting to put together an un-assembled VEMS v3.3 for a Turbo BMW 1989 325i. *BMW M20B25 *VEMS v3.3 *Stock 60-2 Crank Trigger Wheel and VR Sensor *Hall Sensor (from VEMS Web Shop) for Cam Sync (Magnet on Cam Gear) *6x Low-Z 893cc/min (85lb/hr) Injectors *6x Coil "Near" Plug *Bosch 3-Wire Idle Valve I have some questions. Here are the changes I have planned so far. '''Power Supply''' *'''Question''': What kind of fuse for "450mA F1 on PCB"? Is there a recommended fuse type or installation method? *'''Question''': Do I need to connect D45? I am not using a Stepper Motor. *'''Question''': Is PCB v3.3 supposed to have "D37 Transient supression diode"? My PCB v3.3 board does not have a big diode on it. '''Genboard Changes for Primary Trigger: VR''' *Jump JS6 *Short JP2 to JP7 '''Genboard Changes for Secondary Trigger: Hall''' *Remove C103 - '''Question''': Is this the small diode in the middle of the last picture? De-solder and remove it? '''Genboard Changes for Low-Z PWM Injector Driving''' *Install Power Flyback Board (pictured below) *VEMS Wiki Low-Z PWM Pages **GenBoard/VerThree/LowZInjectors **GenBoard/Manual/DDFlyback **GenBoard/Manual/PowerFlyback **http://vems.hu/www.vems.co.uk/VEMS/InjectorFlyback.html '''Anti-Lag VEMS Wiki Pages''' *MembersPage/GaborRacz/NewAlsLaunchAndOthers *AntiLagSystem '''PCB v3.3 Assembly and Testing VEMS Wiki Pages''' *BuildProcedures/SectionThree *GenBoard/Manual/InitialTesting/VerThree '''VEMS Distributorless Ignition Wiki Pages''' *DerrickScirocco/DistributorlessInstallation http://kai.caltech.edu/e30turbo/VEMS-assembly/IMG_1373_resize.JPG http://kai.caltech.edu/e30turbo/VEMS-assembly/IMG_1374_resize.JPG http://kai.caltech.edu/e30turbo/VEMS-assembly/IMG_1375_resize.JPG http://kai.caltech.edu/e30turbo/VEMS-assembly/IMG_1376_resize.JPG http://kai.caltech.edu/e30turbo/VEMS-assembly/IMG_1377_resize.JPG http://kai.caltech.edu/e30turbo/VEMS-assembly/IMG_1378_resize.JPG http://kai.caltech.edu/e30turbo/VEMS-assembly/IMG_1379_resize.JPG
