How fast should the Emu Pro switch off after Ignition OFF

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.

You need pull down on switched 12v
