Product Description
EDGE PRODUCTS 26402 EVOHT2 WITH ECM UNLOCK TOOL – FOR 2017–2019 GM L5P DURAMAX
The EDGE PRODUCTS 26402 EVOHT2 WITH ECM UNLOCK TOOL is the complete tuning solution for the 2017–2019 GM Silverado/Sierra 2500/3500 L5P Duramax. Because the factory L5P ECM is encrypted, tuning requires both a handheld programmer AND a proprietary unlock device. This kit includes everything needed to legally and correctly unlock your ECM so you can apply Edge’s EVOHT2 calibrations for improved towing power, throttle response, and driveability.
The EVOHT2 provides multiple power levels depending on fuel quality, driving style, and load demands. This handheld tuner also offers speedometer correction, DTC reading/clearing, tire size calibration, throttle sensitivity changes, and other important adjustments. After the ECM unlock procedure is completed using the included hardware, you simply flash your desired tune using the EVOHT2 handheld.
This kit is ideal for daily driving, towing, and enthusiasts who want enhanced drivability from their L5P without altering emissions hardware. The EVOHT2 maintains OE emissions equipment functionality and is designed for emissions-equipped trucks.
