Dang, No I don’t have the truck anymore.

Experiment on another vehicle. You can pull a spark plug to create an obvious compression problem. Then screw in a compression tester hose to make it less obvious.

Once you get the voltage settings figured out then experiment with filtering to clean the waveform up.
