I bought this before I bought my digital dash. Since the dash has an ECU interface, I can’t use this. It will connect to any AEM EMS and display almost any ECU parameter, it’s customizable in a number of ways. It’s never even been out of the box.
Here’s info from AEM:

The cheapest I found it was 190 shipped.
