Cardash

Cardash uses a Raspberry Pi witha 2.8" TFT touchscreen to display ECU data via the OBD-II protocol.

The data is processed by Nodejs and sent to a webpage that uses Socket.io to update in real time. Chromium is used to display the web page. Tapping the touchscreen display allows you to cycle through different gauges.
