Magnetic crank trigger?

[buzzinhalfdozen]

OK Art, I'm seeing what you're dealing with. Without the missing teeth the only way the ECU can determine crank angle is to have a sync event just propior to the trigger event, is that correct? Seems like you should be able to calculate the offset shift based on how many degrees you change the cam shaft phasing divided by 2? Don't know why but I love this stuff as it can easily fry a mind as challenged as mine. Good luck and please let me know how you make out. Joe BTW, I believe what you're seeing as far as the point at which your timing light is showing the sensor as being in the middle, more or less instead of the edge of the tooth has more to do with "time" it takes time to trigger, then to fire the coil, then to trigger your light, at least that's how I see it, I wouldn't overly concern myself with that aspect.
