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.

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).

BUT I AM GOING TO USE THE CAMTRIGGER, NOT DISABLE IT. THEREFORE USING 02 DOSEN'T HELP ME AT ALL, AND I CAN'T FIND ANYTHING ON THIS PAGE RELATED TO HOW TO SET UP SECONDARY TRIGGER. JUST HOW TO DISABLE IT!! 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
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..
