How fast should the Emu Pro switch off after Ignition OFF?

I recently noticed the ECU is still logging in the client while I switch off the Ignition.

I even tried to remove the usb to can usb cable from the laptop and connect it later on.

Still channels logging was running.

The ECU has permanent power and switched.
