EZ LYNK AutoAgent 3 Tuners & Tune Files
Shop EZ LYNK tuners and tune files for a diesel setup built around your truck. Choose an AutoAgent 3 device, tune-only service for an interface you already own, or a device-and-tune package. Available products cover selected Ford Powerstroke, RAM Cummins, GM LML Duramax, and Nissan Titan XD diesel applications.
The first decision is simple: do you need the device, the tuning service, or both? Once that is clear, match the engine and model year, then compare Single Tune and available Shift-on-the-Fly options. You can keep useful equipment you already own and put your budget toward the service you need.
What Does an EZ LYNK AutoAgent 3 Tuner Do?
AutoAgent 3 connects to the truck’s OBD-II diagnostic port and communicates wirelessly with the Auto Agent app. You use a supported phone or tablet to view available live data, read diagnostic trouble codes, record logs, and access assigned vehicle profiles.
Unlike a traditional handheld tuner with its own screen and buttons, the EZ LYNK system centers on the mobile app and technician connection. The device provides the vehicle interface. Your purchased tune service supplies the calibration for the truck.
The device’s Wi-Fi connection links your phone to the vehicle. Internet access is used for tasks such as retrieving assigned files and communicating with the technician. Follow the supplied instructions when switching between the vehicle connection and an internet connection.
Device Only, Tune Only, or Device + Tune?
-
Device Only: Choose an AutoAgent interface when you need the hardware. Vehicle-specific tune service is not included with a device-only selection.
-
Tune Only: Choose the listed service for your truck and use a compatible AutoAgent you already own.
-
Device + Tune: Choose the AutoAgent hardware and the selected tune service together when you need a new setup.
Product cards show a starting price across the available selections. The final EZ LYNK tuner package price depends on the vehicle, device requirement, and tuning option you choose.
EZ LYNK Tune Files for an Existing AutoAgent
Already own a compatible device? EZ LYNK tune-only options let you purchase the vehicle-specific service without buying another interface. This is useful when you are adding service to your current truck or arranging a new service for another supported vehicle.
For a secondhand device, identify the AutoAgent model and account access first. Previous ownership of the hardware does not establish access to another truck’s paid profiles. The vehicle details, technician association, and purchased service need to match your order.
Single Tune vs. Shift-on-the-Fly Tuning
A Single Tune option uses one selected calibration. It suits an owner who wants a chosen setup without switching between power levels while driving.
Shift-on-the-Fly, commonly called SOTF, allows switching between supported power settings without reflashing. The available levels and switching method depend on the truck and supplied tune. Review the selected package for the required switch, wiring, and included accessories.
Choose a service around the way you use the truck. Describe the load, terrain, transmission, and current modifications when discussing a towing setup. The highest power setting is not automatically the best towing choice, and tuning does not increase the manufacturer’s rated towing capacity.
EZ LYNK Tuners for Ford Powerstroke
When choosing an EZ LYNK tuner for a 6.7 Powerstroke, match the model-year group and Pickup or Cab & Chassis selection. The current 6.7L tune-package listing covers selected 2011–2025 applications, with separate year choices inside the product.
Ford 6.4L and 3.0L Powerstroke applications use separate products. The current 3.0L F-150 tune listing covers 2018–2019 and offers Single Tune selections. Do not assume a SOTF option from another Ford listing applies to it.
EZ LYNK Tuners for Cummins, LML Duramax & Titan XD
For an EZ LYNK tuner for a 6.7 Cummins, match the listed year, chassis, and transmission. RAM selections can distinguish Pickup, Cab & Chassis, Aisin, and 68RFE applications. These details help identify the service for the actual truck.
The standalone GM package in this collection is for selected 2011–2016 6.6L LML Duramax applications. It is not an L5P tune package. Nissan Titan XD owners should select the 2016–2019 5.0L Cummins diesel application within the matching product.
Monitor, Diagnose & Work with Your Technician
Use the Auto Agent app to view available readings such as boost, coolant temperature, and transmission temperature. Record a log when your technician needs more information about how the truck is running.
Diagnostic trouble codes help identify what needs investigation. Clear them after the cause is repaired. Available gauges and functions vary by vehicle and controller, so a general monitoring connection does not establish coverage for every service function.
The EZ LYNK tune-service guide explains how the interface, account, technician, and assigned files work together.
Understand Tune Delivery and Support
Tune files are accessed through the Auto Agent app after the required preparation and vehicle linking. Physical delivery of the AutoAgent is separate from file readiness. Keep your VIN and modification details ready, and follow the setup instructions supplied with your order.
Engine tuning and TCM transmission tuning are separate services. A SOTF selection does not automatically include a transmission calibration. Likewise, a Lifetime Support label describes the selected service terms rather than a promise of replacement hardware or transferable tuning for every truck.
Current tune listings state that PTO tuning is not supported. Owners of work trucks with PTO equipment should address that requirement before ordering.
Need Physical Hardware with Your Tuning?
An EZ LYNK delete tuner or tune-file service does not include EGR or exhaust parts unless they are listed in the order. If you also need those components, compare the EZ LYNK delete kit packages instead of assuming a tuner purchase supplies the hardware.
Emissions-delete calibrations are not street-legal replacements for required emissions controls. AutoAgent diagnostic and monitoring functions are separate from the calibration service selected for the vehicle.
