The crash has been rectified Victor and we are testing a "Release Candidate" version as we speak.
Hello,
Some good news about the improved version?
Will be available an"automotive brother" of Pico 5442D MSO?
Thank you

Re: Limitation of waveform buffer memory

Hello,
I will upload the crash report from waveform buffer memory,if the CAN decoding is enabled the PICO crash every time,if not then I can store more than 70 frames in memory buffer.
Best regards

Re: Detonation Waveform

Hello,
I think your knock sensors signals captured by a scope and a reference will be the best option,other option is to check with a scanner the ignition advance for bank 1 and bank 2 when the knocing occur :)
