Understanding CAM and crank sensor
I have attached an image of injectors, ignition, CAM- and cranksensor at cranking speed. The vertical red line indicates signal from the CAM sensor - and approx. 60 degrees later the first cylinder is fired (green line). Can anyone tell me the relationship between the CAM sensor and the angle of the system?
To me it seems that the CAM sensor is triggered 90 degrees before TDC but I'm not sure that's correct. Furthermore the CAM sensor sends two more signals - anyone who know what they are used for?
By the way the data is from a CBR600RR 2005 engine.
