Page created to cleanup specs
Note that if ECU is manufactured to specs, but the specs is wrong, it will not work. Sectrig=HALL (cam), we can agree on that... However, even after several "we are sure emails", primary trigger=HALL is specified which we think is wrong. On single-Vanos M50 engines (also considering the more detailed info) cranksensor should be VR.
Primary trigger
- according to our information, crankshaft=VR (connected as primary trigger in VEMS)
- please confirm crankshaft=VR.
- Preferrably by DVM measurement: if you find 2 pins that measures same resistance in both directions (usually between 300 and 1400 Ohm) that is VR. Otherwise HALL.
Probably wrong info below, saying crankshaft=HALL (info mounting in emails before this page was created)

3 PIN Hallsensor Crankshaft (editors note: must be wrong)

we are sure - Motorcode M50 S256S2, with single Vanos - Hallsensor Crankshaft with 3 pins (editors note: must be wrong)
