Features:

• In-Vehicle ECM/TCM Unlock — Unlock the factory ECM and TCM without removing them from the truck, providing straightforward access to Edge performance and transmission tuning.
• Four Pre-Loaded Performance Levels — Choose from Economy (+50 HP/+100 LB-FT), Towing (+75 HP/+160 LB-FT), Performance (+90 HP/+180 LB-FT), or Extreme (+125 HP/+275 LB-FT) to match your truck's performance to how you drive.
• 10-Speed Transmission Tuning Included — Optimize shift strategies, shift feel, power delivery, and drivability to complement each performance level.
• Adjustable Throttle Boost — Fine-tune accelerator pedal sensitivity for quicker throttle response and a more responsive feel behind the wheel.
• Improved Acceleration — Testing showed gains of up to 1.3 seconds and 8 MPH in the quarter-mile, demonstrating the added performance available from Evolution tuning.*
• Built for Daily Driving & Towing — Multiple tuning levels, optimized transmission strategies, and adjustable throttle response let you tailor your truck for commuting, towing, hauling, or maximum performance.
• Advanced Diesel Monitoring — Monitor important supported parameters including DPF soot level, miles since last regen, EGT, boost, fluid temperatures, and other critical engine and drivetrain data.
• Command Manual DPF Regeneration — Initiate a manual DPF regeneration cycle when supported directly from the CTS4.
• Remember Factory Button Settings — Retain supported settings for drive mode, exhaust brake, Tow/Haul, and grade braking instead of resetting them each time the truck is started.
• Adjustable Tire Size & Speedometer Calibration — Correct the speedometer for supported tire sizes from 26 to 38 inches.
• Allison Transmission Relearn — Access the supported Allison transmission relearn procedure directly through the CTS4.
• Adjust Speed & Rev Limiters — Modify supported vehicle speed and engine RPM limiter settings to better match your truck's configuration and intended use.
• Adjustable Idle-Up — Adjust supported idle speed from 600–1,800 RPM for greater control when stationary.
• Customizable Digital Gauges — Configure the CTS4 display around the engine, transmission, DPF, temperature, pressure, and other supported parameters that matter most to you.
• Custom Alerts & Data Logging — Set alerts and warnings for supported parameters and record vehicle data for performance monitoring, towing, and troubleshooting.
• Built-In Diagnostics — Read and clear supported diagnostic trouble codes directly from the CTS4.
• Expandable Monitoring — Add compatible EAS sensors, EGT probes, pressure and temperature sensors, and camera options as your truck and monitoring needs evolve.
• Emissions-Friendly Performance — Calibrations are developed to deliver clean, efficient, DPF-friendly performance and have passed Edge's in-house emissions testing, with CARB EO submissions being processed.
