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?
