Edge Insight+ CTS4 Monitor with Custom Tune License

Note: CTS4 is a new release from Edge. Orders placed now are pre-orders and ship in the order received as stock arrives, expected early November 2026.

The Edge Insight+ CTS4 is a full digital monitor with a pre-loaded custom tune license. Run it as a gauge display, or use it to back up the factory calibration and flash custom tuning from approved third-party tuners on supported Powerstroke, Duramax and Cummins diesels.

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

Monitor First, Custom Tune When Ready

• Custom Tune License included: flash calibrations from approved third-party tuners as the build grows
• Saves the factory calibration before any flash, so returning to stock is a single step
• Runs as a full-featured monitor with or without a tune loaded

Monitoring and Diagnostics

• Real-time gauges for EGT, boost, transmission temperature, coolant temperature, DPF soot load, regen status and dozens of supported parameters
• Custom alerts and warnings on supported parameters
• Integrated data logging with export
• Read and clear diagnostic trouble codes
• Built-in performance tests: 0-60 MPH, 1/4 mile and more
• Wi-Fi updates keep the device current without a computer
• Expandable Accessory System (EAS): add EGT probes, pressure and temperature sensors, or the CTS4 backup camera

Installation
