Evolution CTS4 2020-2023 GM L5P Duramax

The Evolution CTS4 for GM L5P Duramax delivers powerful tuning, a sleek touchscreen, and real-time engine monitoring. Boost towing power, throttle response, and efficiency with this premium all-in-one tuner and performance upgrade.

**Device can unlock and tune only one vehicle. Once the ECM is unlocked and flashed, the vehicle can be returned to the factory calibration, but the unlock process cannot be reversed. Once VIN lock and ECM/TCM unlock have been completed, the device is non-returnable.

• 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.
