I made a video of my measuring the electromagnetic valve and the camshaft waveforms of a BMW E66 740LI with DS203. It is really helpful for car maintenance.

There you go on the Youtube!
I thought this DS203 nothing special. But it turns out that it serves well to measure the waveforms for diagnose of car problems. I love it!
I hope I can develop more improved firmware in the future such as one with an electric current measurement function. That is what I badly need.
03-15 update. Practical case: the diagnose of problems of a BMW E70 X5 351 by K-CAN waveforms.

04-22 update. Measure the BMW X5 E70 E52 engine timing waveforms with the oscilloscope to see if the engine timing reaches the right position.
