The BigMotronicPnP is on hold for a while until I have time again.
In the mean time I´ll be supplying VEMS PDF wiring info.

Here is crank and cam captures for BMW M52 engine single vanos.
Can this cam sensor be made to work?
The ignition signal is number 1 cylinder.
Back to the above question , Can this be made to work?
What is happening is that the frequency changes during the toothed section and then go back to lower frequency when the tooth has passed, surely this can be implemented?
Would need fw mode. Currently the supported method (also see MembersPage/JasonVoytilla/BMW/Sensors
) : '''HALL replacement sensor: BMW 12 14 1 438 081 - Hall Effect Falling Edge. Pinout (from 1993 BMW .. .pdf document page#106 (m50 vanos)
- 1) power
- 2) signal
- 3) ground
Note: m52 page#98 has camshaft sensor middle (pin#2) going to mot88/pin64
That matches Gunnar's xls for camshaft (just forgot to mention HALL). So
- EC36/13 camHALL input= BMW88/pin64 (middle pin on the replacement HALL sensor connector)
- EC36/26 GND BMW88/pin43
- MOT88/pin54 +12V BMW88/pin65 +12V for HALL sensor (powered by the main relay, actuated by EC36/16)
