Here's a guide from https://www.powerpyx.com/borderlands-3-dlc-2-guns-love-and-t...
it has pictures for those who don't wish to watch the videos or just prefer a text & picture guide.
Borderlands 3 (BL3) has 18 ECHO Logs in the Guns, Love, and Tentacles DLC #2. They are needed for the Whispers on the Wind trophy or achievement.
None of the ECHO Logs are missable! You can still find all of them after the story in free roam. However, they are not marked on your map or tracked by region. You might want to collect them all in one go to avoid confusion about what you’ve already picked up.
They are referred to by their Names. If you have picked up a few, check your ECHO, go to Log and hit D-Pad right to get an overall list of what you’ve collected.
