I checked out some of the the Pico Scope videos and it is awesome.
$1,000++ is a big price tag but that investment works out over time for those who wrench at home.
Their website, documentation, and interface features could use a few more user-friendly tweaks, but it looks to be a powerful tool still.
Find the source of road vibration. Find electric component flaws. Find relative compression. All with hooking up a few sensors and running some tests. No throwing a pile of parts at an unknown problem. And clean hands stay clean.
You notice in the video he points out problems such as the starter motor probably skipping a beat, and the #1 cylinder having over-spec compression and possible causes.
-This is not pointed-out by the software itself and there is some theory applied there which requires mechanical experience.
-All of those could be added as pop-up warnings or highlighted by the software as readings out of normal.
-The entire program routine could be customized by selecting from a simple job menu at the very start and graphs/scales are preset for easy reading.
-The job menu could have stock pictures for which sensors to use and where to attach them. It could even go deeper into standards for each model of vehicle.
-With all 4 sensors attached, it could run multiple diagnostics automatically all at the same time.
-Even better hypothetically would be plugging only one simple plug into the 16-pin OBD2 port and getting it all, but I think the refresh rate on those are too low for these tests.
If you have the time to sit in on discussions by the pros..."Trained by Techs" is also a channel worth watching:
