nigel bobbin Posted February 6, 2011 Report Share Posted February 6, 2011 I am tying to understand how the cam sync signal works, i have a bmw M10 engine that i am going to use a link ECU on. This engine did not have cam/crank sensors on originally. I have made the crank sensor with a 36/1 missing tooth wheel with a reluctor sensor and understand how to set it up. No problem there My question is how to trigger another reluctor for the cam sync signal. where do i need to trigger the cam sensor. I.E do i use a pulse at TDC on cylinder 1, or just put a pulse at any crank angle. also what are the correct settings in the link software ?

Jurgen Biggelaar Posted February 6, 2011 Report Share Posted February 6, 2011 Hi Nigel. The sync pulse usually appears between the last, and first in the firing order. When the ECU sees the sync, it will want to fire from #1 on the next firing event. Here is an example set up of how I think yours should look when done. Please keep in mind I am not aware of the sensor locations on your vehicle, so the multi-tooth posn. on trig1 & Sync mode on trig2 should resemble their actual physical location. http://i903.photobucket.com/albums/ac236/linkelectro/examplemultimissing.jpg Jurgen Quote Link to comment Share on other sites More sharing options...
