One bundle. No compatibility guesswork. This complete LWN tuning package is designed specifically for 2016–2022 Chevrolet Colorado and GMC Canyon trucks equipped with the 2.8L LWN Duramax. It includes the required OBD2 flash interface, delete tuning file, and activation credits—so you can plug in, read, and flash without mixing separate hardware and software components.
For off-road use only.
Instead of sourcing an interface, purchasing credits separately, and wondering if files match your hardware, this bundle delivers everything required to write your LWN delete calibration immediately. Built for off-road applications, it provides selectable power levels and a streamlined installation process through the vehicle’s factory OBD2 port.
