Edge Evolution CTS3 w/Locksmith (85400-262) For 2017-2019 Duramax L5P

Edge Evolution CTS3 L5P Duramax Tuner and Monitor

The Edge Evolution CTS3 delivers advanced tuning and monitoring for 2017–2023 Chevy Silverado and GMC Sierra trucks equipped with the 6.6L L5P Duramax. This device combines flash tuning, real-time monitoring, and diagnostic tools into one system. As a result, L5P Duramax owners gain improved horsepower, stronger towing performance, and detailed engine data.

The kit includes the Edge Locksmith module, which unlocks the factory ECM through the OBDII port. Once unlocked, drivers can install emissions-friendly performance calibrations directly from the device. These calibrations support daily driving, towing, fuel economy, and performance use. After flashing the calibration, drivers can unplug the tool and enjoy reliable power gains.

Power Gains and Tuning Levels

This system delivers significant performance improvements for the L5P Duramax platform. Depending on the selected tune level, power gains can reach up to 150 horsepower and 350 lb-ft of torque at peak RPM.

Drivers can choose from several tuning levels designed for different driving conditions.

Economy tune provides up to 75 horsepower and 150 lb-ft of torque
Tow tune provides up to 100 horsepower and 200 lb-ft of torque
Performance tune provides up to 125 horsepower and 250 lb-ft of torque
Extreme tune provides up to 150 horsepower and 350 lb-ft of torque

These tuning options improve throttle response and provide stronger pulling power. As a result, towing and heavy-load driving become smoother and more controlled.

Advanced Monitoring and Display

The CTS3 monitor features a large 5-inch high-resolution touchscreen display. This screen provides real-time vehicle data and customizable gauge layouts. Drivers can monitor important parameters while driving.

The monitor displays information such as soot levels, miles since the last regeneration cycle, exhaust gas temperatures, boost pressure, and fluid temperatures. Therefore, drivers can track engine performance and identify potential issues before they become serious problems.

The touchscreen interface also allows drivers to swipe between monitoring screens quickly. In addition, the device supports performance data logging for reviewing engine performance after a run.

Transmission Tuning and Vehicle Controls

The Evolution CTS3 also supports advanced transmission tuning features. The system includes TCM calibration through OBDII flashing. This feature improves shift behavior and drivability on trucks equipped with compatible transmissions.

Drivers also gain access to several adjustable vehicle features. For example, the system can recalibrate tire sizes for 26–38 inch tires. The device also allows adjustment of speed and rev limiters.

Additional features include Throttle Boost, which adjusts pedal sensitivity for quicker throttle response. Drivers can also command a manual DPF regeneration cycle when necessary. The system also includes Allison transmission relearn and idle-up adjustment from 600–1800 RPM.

Diagnostics and Data Logging

The device includes built-in diagnostic tools that simplify vehicle maintenance. Drivers can read and clear diagnostic trouble codes directly from the monitor.

The system also supports data logging and performance monitoring. Drivers can record vehicle data while driving or during performance runs. Later, they can review the logs to evaluate vehicle performance and tuning results.

Installation and Compatibility

Installation remains quick and straightforward. The device connects directly to the OBDII port and mounts inside the cab for easy viewing. The touchscreen monitor provides a modern digital gauge system inside the vehicle.

A PC with the Edge Update Agent software is required to complete the tuning process. The device can unlock and tune only one vehicle. Once the ECM unlock occurs, the device becomes locked to that VIN. Although drivers can return the truck to the factory calibration, the unlock process cannot be reversed.

The calibrations maintain factory emissions systems and support DPF operation. However, the device does not support the removal of emissions equipment.
