Do U-Scope? (Episode 4) Real-World Scope Tests: Relative Compression Test
In this video, I break down how to perform a Relative Compression Test using an oscilloscope. This fast, non-invasive diagnostic method lets you check engine health without removing spark plugs. You’ll learn how to set up the test, connect a current clamp, record the waveform, and interpret compression peaks to identify low or dead cylinders.
This test is extremely useful for misfires, hard-start conditions, and high-mileage engines. We cover good vs bad waveforms, timing issues, sync channel setup, and real shop examples.
If you’re learning automotive oscilloscope diagnostics, fuel trim, waveform analysis, or Subaru mechanical failures—this is for you.
