You can just take a coil from BMW E30 or any other car that doesnt have that stupid module and release yourself a trouble! I think a coil from 325i will do the work and it will work with ur current ignition setting in MT

i was checking injector output , with dvm and i get beep while crancking. it grounds, and seems ok.
but no beep on pin35 coil00.

2bmw :  i have coil without ignition module connected. problem seems to be in vems, it doesn't connect coil trigger to ground.
so i was thinking to change ign output to pin36 and use coils 4pin ignition module, but i dont know what changes need to be done on vems board. (i have onley ign00 driver onboard).

don't have any spares...

changed rpm constant to 2000. got 173 rpm

also changed refrence table to

40
20
0
40
20
0

as suggested by fire. still no beep or reading from dwm from ign00 to ground.
;D
seems like dead ign driver ...

any suggestion how to use external bosch? onley connect it from pin 36 to pin4 ond coil driver  without driver soldered to board? will it work? or do i need to bridge somethig?

i just looked at youre msq,this is 1.1.44? maybe you should try with 1.0.73 first...
Mine engine (bmw m20) doesnt start when set to Alternate (only when set to All banks) in Injector Setting>Fire banks while cranking (at the bottom of the settings),just a note...

thx bmw.

got spark today,  using diefferent coil DOH! fire says that my cheap dvm can't measure short as 2ms ingn output.... so new coil and voila! :)

but, i made a mistake.

when i got the spark, i put fuse for injectors and tryed to start the car. nothing.

didn't re check wiering, and after connecting and disconecting everything when trying to get the spark.
i didn't conected injector outputs 1 2 3 4 5 6. flyback was connected , and fuse to flyback / injectors was installed.
so i think i maybe blown some fets? ? ?

got no beep using DVM. later rechecked and i  hear beep on chanels 3 4 5 6. on 1 and 2 nothing.

after trying to start every time this on vems gets "corrupted"




insted 20 and 0




and here under #6 adn #7 idestead 64 and 128

after correcting valeues  if i try to start the car, same thing happens. with random values... in the same place.
