Link CAN Gauge OLED 52mm The Link CAN Gauge is a compact OLED gauge for displaying real-time data from your Link ECUs CAN stream. Supported parameters such as boost pressure, air/fuel ratio, coolant temperature, fuel pressure, ethanol content, etc. can be displayed. The high contrast OLED display is bright for interior use and dims at night. Configure 1, 2, or 4 gauge layouts on up to 10 different pages. Pages can be scrolled through using the easy to access front buttons. Create customizable warning points, such as the coolant temperature being too high, which trigger a special warning screen and bright LED on the face of the gauge. Easily customize your CAN Gauge to display the data you want to see with the free to download app (compatible with Android 4.4 or later and Apple iOS). The easy-to-use app works with your smartphone or tablet to wirelessly customize your gauge in minutes and is a lot easier than trying to configure your gauge with only buttons on the front!  Box Contents
