Summary of change:
Hi I have a BMW 1991 520i that i really think needs more power. The plan is to use the genboard with a 1991 325 engine. The engine will hopefully be supercharged, but initially I will try to get the engine running on the genboard with all the original features, like camsync and sequential ignition. My setup will be something like this: BMW m50b25 Lowered compression with JE forged pistons (8.5:1) Total seal gapless rings ARP headstuds MLS headgasket m30 flywheel stronger clutch(havent decided on this one yet) stock crankshaft, connecting rods and heads. EATON m90 supercharger from an american FORD supercoupe 490cc/min injectors (ACCEL) MSD blaster ss coils Aeromotive FPR Walbro GSS 340 fuelpump The engine is 6cyl, 24 valves, DOHC, non-vanos Vems genboard v3.2 serial 203 Using stock triggers (VR/VR) WBO2 heater #1 IGBIT 1-6 for ignition and FET A-F for injectors Using modified bosch motronic casing for this so i can retain the stock wiring loom for the coils and many of the sensors. But I will use other non-stock coils and in a while when i am coming to supercharging the engine the throttlebody on the supercharger unit will be used. This all in all results in that I will have to make a seperate wiring loom for many of the components. Therefore the motronic case will also contain the Econoseal connectors, making it a rather strange casing. ---- '''22.05.2005''' Questions about camsync. I've been trying several configurations now, but when I try to enable secondary_trigger, the only thing that happends is that the rev counter on the LCD counts the revs, which are correct btw. (I am simulating this with a file recorded from the engine that is in the car now) None of the light bulbs connected seem to react). ...The triggerpart of my config file... <code> ############################################################# # # Triggers, HW determines VR or Hall # software defines how it reacts # # # ========== 60-2 Trigger Configration ==================== # # ======Primary_Trigger ==================== # FE: Rising Edge trigger # FF: Falling Edge trigger # 01: Multi-tooth configuration primary_trigger=01 # Multi-Tooth configuration # tooth_wheel: # Used for multi-tooth wheels # Total number of teeth # eg For 60-2 wheel, 58 teeth between the missing tooth = 3A # eg For 36-1 wheel, 35 teeth between the missing tooth = 23 tooth_wheel=3A # tooth_wheel_twidth1: # width (in degrees) of each tooth # eg For 36-1 wheel, each tooth is 10 degrees = A tooth_wheel_twidth1=6 # trigger_tooth: # Used for multi-tooth wheels (Tooth that triggers event) # so that trigger tooth is ~60 degrees BTDC trigger_tooth=00 # so that trigger tooth is ~60 degrees BTDC cam_sync_r_edge_phase = 141 (dec) # ======Secondary_Trigger ==================== # FE: Rising Edge trigger # FF: Falling Edge trigger # 01: Multi-tooth configuration # ??: Cam Sync setup? # FF = disable, even prevents inj and ign firing # 02 = disable, but allow inj and ign firing # http://www.vems.hu/wiki/index.php?page=GenBoard%2FUnderDevelopment%2FFirmwareChanges # please help identify/kill bad recommendations about this found anywhere secondary_trigger=02 cam_sync_r_edge_phase=FF cam_sync_f_edge_phase=FF reset_engphase_after=FF # another_trigger_tooth: decimal 20 is used for 60-2 toothwheel and 6 cylinder (3 events per crankrot) another_trigger_tooth=14 # not used without camsync tooth_wheel_twidth2=12 </code> '''And if someone could explain these parameters for me..''' ''cam_sync_r_edge_phase'' ''tooth_wheel_twidth2'' ''trigger_tooth'' ''cam_sync_r_edge_phase'' ''cam_sync_f_edge_phase'' ''reset_engphase_after'' And how they are to be set up. I am kinda out in the fields here..
