I started playing with my new Picoscope 4425A and found a “cylinder balance test” in the included software program. This is a guided function that involves connecting leads to the 12V battery, cranking the engine and allowing it to idle, followed by selecting the number of cylinders and allowing the software to perform its analysis. Here is more info on the test:

I am curious how battery/system voltage alone will allow a software program to determine cylinder balance. The software must be using differences in voltage drop to signify differences in compression between cylinders? I wonder if the test is as accurate as a relative compression test.
