EZ LYNK Tune Package with Auto Agent 3

The Spelab EZ LYNK Tune Package offers a streamlined, cloud-connected solution for tuning and diagnostics specifically designed for 2011-2023 GM Duramax LML and L5P trucks. This system utilizes the EZ LYNK Auto Agent 3 device, which connects to your truck's OBD2 port and interfaces with the EZ LYNK mobile app via Wi-Fi. This enables remote management of performance, real-time data monitoring, and direct technician support without the need for cables or traditional handheld tuners. Key features include Switch-On-The-Fly (SOTF) support, where 2017-2023 L5P trucks utilize factory steering wheel buttons to switch between power levels, eliminating the need for an external switch. Setup is designed to be quick, taking approximately 60 seconds: plug the Auto Agent 3 into the OBD2 port, install the EZ LYNK app on your Android or iOS device, and connect via Wi-Fi. The package also functions as an advanced diagnostic scan tool, allowing you to read and clear Diagnostic Trouble Codes (DTCs) and perform other recommended functions. Tune management is facilitated through the EZ LYNK cloud, enabling access and installation of tune files remotely. Automatic data synchronization ensures VIN-locked tuning integrity. This system is also fleet-ready, supporting data log sharing, maintenance reports, and remote diagnostics for both individual owners and fleet managers. The Auto Agent 3 device connects via OBD2, communicates through Wi-Fi with the mobile app (iOS 12.0+ and Android 8.0+ supported), and allows for cloud-based remote tune installation and over-the-air updates. Installation is straightforward, taking about a minute. For L5P Duramax models from 2017 to 2018, an ECM unlock service or an unlocked ECM is required before installing tuning files. This package is **not compatible with** E66 ECM or Global B electrical architecture (found in some late 2022 trucks). The package is compatible with GM 6.6L Duramax LML engines from 2011–2016 and L5P engines from 2017–2023, specifically for Chevrolet Silverado HD and GMC Sierra HD 2500HD and 3500HD trucks. All tunes are custom and non-refundable, and tuning files require 7–10 business days to create.
