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
