PicoScope 7 Automotive
Available for Windows, Mac, and Linux, the next evolution of our diagnostic scope software is now available.
My best guess not seeing your capture is that you didn't select opposite polarity ignition probes in the software. On your paired cylinders, one cylinder will fire negatively (electrons from center to side electrode of plug) and the other cylinder fires positively (electrons from from side to center electrode).Why could I not see the spark pattern on all four HT leads when testing with picoscope?
