I've had a Picoscope for a good while now and love it, trying to find the time to collect good data can be pain though.
I look forward to getting to grips with it and hope I can help add some useful resources at some point.
Spending a bit of time collecting (and saving) known good waveforms is time well invested. You learn so much about how a modern vehicle works as well as learning how to use the PicoScope. It is worth doing your homework
