ive never owned a bm so cant say for that

the z20net and the lsj have individual coils its the z22se coil pack that has to be adopted to the z20net in this case
so trying to reverse engineer the single coils back on to the z20net but with the drive of the z22se ecu
they do look better on the engine than the modified z22se dis pack

think the main problem now is the simulated cam signal but other than that it will work
