My EDS seems to take a few goes before it connects.

After initial installation and with the engine running the EDS may take a minute to establish a reliable data link. If EDS cannot find a reliable connection it will switch off within a minute.

Once EDS has established a reliable data link with your vehicle it will generally link immediately every time you start your vehicle.
