You have set wheels in motion in my head again and so I will try to capture a vehicle on site where by we can assess the compression waveform in relation to Cam and Crank correlation.
Thanks again for the input
Here again is where I am at a loss and would value any input. I have attached a psdata file looking at CAM-CRANK-CYLINDER PRESSURE-IGNITION PRIMARY NO.1 cylinder. Moving along to next ignition event after NO.1 cylinder (identified by time rulers) I have added a maths channel to channel A measuring frequency which you might expect to see increase momentarily after the ignition event whilst on the power stroke, but the data does not support this theory!
