It's hard to speed up. Please convert the administrator to MWF format. Thank you very much

Hi,
Your waveform has been converted to *.mwf format.
Unfortunately, your file contains 8 frames and script results are not accurate.

I recommend you to download Pico 4225/4425 settings needed to record properly the cylinder pressure waveform:
viewtopic.php?f=3&t=29

Record your waveform again according this test procedure:

Thank you very much, administrator. It's the first time for me to talk with international auto repair colleagues

I'm a 22-year-old car repair guy from China. All my English is translated into English after I input Chinese

I really like your diagnosis


If USB oscilloscope can have Chinese language like Pico, it will be perfect

Thank you thank you

Thank you for sharing this detailed explanation and resources. It's great to see such collaborative troubleshooting. I was wondering, would compressing and optimizing waveform files make them easier to share and analyze?
