The Edge Insight CTS4 digital gauge monitor puts live engine, transmission and emissions-system data on a 5.5-inch touchscreen without tuning the truck. It plugs into the OBD-II port, covers most domestic gas and diesel trucks from 1996 on, and replaces a pillar full of mechanical gauges with one configurable display.

Insight CTS4 is the monitor-only model of the CTS4 family. When you want power, the same hardware upgrades to Evolution tuning or Insight+ custom tuning through an online update. No new device required.

What CTS4 Changes Over CTS3

• 5.5-inch high-resolution touchscreen with 21% more viewing area than CTS3
• 1.7GHz dual-core 64-bit processor: 3.4x the processing power of the previous generation
• 2GB of 3400MHz LPDDR4 RAM, a 300% increase in memory
• 50% faster PID changes, so gauge data updates without lag
• 70% faster cold boot: gauges are live sooner after key-on
• New Quick Action buttons, Maintenance Minder and Peak Value Recall
• Smooth 60 FPS display with customizable gauge layouts and backgrounds
