The Edge Insight CTS4 is the next generation of digital vehicle monitoring, giving truck owners and performance enthusiasts a faster, clearer, and more powerful way to see what's happening under the hood. Designed as a dedicated in-cab digital gauge monitor, the Insight CTS4 connects directly to the vehicle's OBD-II port to display supported engine, drivetrain, temperature, pressure, and other critical vehicle parameters, all without adding a performance tune.

Built on an all-new, more powerful hardware platform, the Insight CTS4 delivers a major performance upgrade over the previous CTS3 generation. A 1.7GHz dual-core 64-bit processor provides 3.4x more processing power, while 2GB of high-speed RAM delivers 300% more memory capacity to support faster gauge updates, programming, and overall responsiveness. The result is 50% less set up time and 70% faster boot times, so you can get the information you need faster.

The Insight CTS4 is designed with an easy upgrade path, allowing you to unlock additional capabilities through an internet update at any time. Upgrade to an Evolution CTS4 to add Edge's emissions-friendly performance tuning, or step up to an Insight+ CTS4 for vehicle-specific custom tuning support.
