It is important to distinguish EAP from traditional pre-release software. Please note that the quality of EAP versions may at times be way below even usual beta standards.

You can setup auto-update of Scala plugin EAP builds in IntelliJ IDEA.
Simply select desired update channel from a drop-down menu at "Updates" tab in Scala plugin settings page.
