EZ LYNK FAQ
Why Buy from SPELAB
What Is EZ LYNK?
EZ LYNK is a connected diesel tuning and diagnostics platform that links the truck, driver, and technician through one system. Instead of relying only on in-person shop visits or manual file transfers, EZ LYNK uses the Auto Agent device, mobile app, and cloud connection to simplify diagnostics, data sharing, and supported tune delivery.
For diesel owners, the platform can support several important jobs: reading and clearing Diagnostic Trouble Codes (DTCs), viewing live vehicle data, recording data logs, sharing diagnostic information with a technician, and receiving supported updates remotely through a wireless connection.
EZ LYNK is also written as EZLYNK, ez link, or AutoAgent — these all refer to the same cloud-connected diesel tuning platform and Auto Agent 3 device.
What Is the EZ LYNK Auto Agent 3?
The Auto Agent 3 is the hardware device that connects the EZ LYNK ecosystem to the truck. It plugs into the OBD-II port, pairs with the EZ LYNK mobile app, and acts as the access point for diagnostics, cloud-based communication, and supported tune-related workflows.
In practical terms, Auto Agent 3 is what makes the platform usable on the vehicle. It allows the truck to send live data, access app-based functions through Wi-Fi, and communicate with a technician when support or file management is needed.
What Comes in an EZ LYNK Tune Package?
An EZ LYNK tune package may include the Auto Agent 3 device, supported custom tune access, diagnostics, live data monitoring, and remote technician communication, depending on the selected product option. Always check the product page before ordering to confirm whether the package includes device hardware, custom tune files, platform-specific support, or other required steps.
Optional Heavy-Duty OBDII Diagnostic Cable
Some installations benefit from a more secure diagnostic connection — especially cab & chassis trucks, medium-duty Ram applications, and other HD configurations. The EZ LYNK heavy-duty OBDII diagnostic cable provides a stable link between the Auto Agent 3 and the vehicle's OBD-II port for these demanding setups. It is offered as an optional add-on; confirm availability and fitment on the product page or with SPELAB support before ordering.

Using Your Auto Agent 3 Day to Day
The Auto Agent 3 plugs into your truck's OBD-II port and connects to the EZ LYNK app over Wi-Fi. It does not need to stay connected all the time — it only needs to be plugged in while you're using it, for diagnostics, live data, data logging, or loading and switching tunes. It can be unplugged for normal driving, and unplugging it when the truck is parked avoids drawing on the battery.
No permanent mount is required. Most owners keep the device in the OBD-II port or within easy reach while using it, and store it when not in use. Once your tune files are available on the platform, you can select and load tunes through the EZ LYNK app, and if your tune supports Shift-on-the-Fly, you can switch between supported power levels without reloading.
The EZ LYNK app runs on iOS 12+ and Android 8+ devices and works directly on your phone rather than through Android Auto or Apple CarPlay. If the app won't connect, make sure the ignition is on, the device is fully seated in the OBD-II port, and your phone's Wi-Fi is enabled. For a factory reset or a Wi-Fi password reset, follow EZ LYNK's official in-app reset steps or contact support.
CAN Commands, Secure Idle & Shift-on-the-Fly
Beyond diagnostics and tune delivery, EZ LYNK supports several platform features. CAN commands are custom commands a technician can build into a tune so you can trigger supported vehicle functions from the EZ LYNK app — what's available depends on your truck's platform and the technician who built your file.
Secure Idle lets the engine keep running while the truck is locked with the key removed, which is useful on work trucks to keep equipment, climate control, or accessories powered while the vehicle stays secured. Shift-on-the-Fly (SOTF) lets you change between supported power levels while driving, without reflashing — often selected with a switch, such as a 5-position switch that selects among up to five levels. Availability of these features depends on your platform and tune.
Using One Device on Multiple Trucks
The Auto Agent 3 hardware can be moved between vehicles, but tune files are vehicle-specific and tied to your VIN. Driving a different truck generally requires a tune file built for that vehicle, and some platforms also require additional unlocks. Confirm with your technician or SPELAB before planning to share one device across multiple trucks.

| Ram / Nissan Package |
6.7L Ram Cummins diesel trucks and supported Nissan Titan XD 5.0L Cummins applications |
Confirm pickup vs cab & chassis fitment, model year, and current modifications. |
| Ford Package |
6.4L, 6.7L, or 3.0L Powerstroke applications, including F-Series pickups and cab & chassis trucks |
Confirm engine size, year range, F-Series model, and whether the truck uses PTO equipment. |

Warranty, Data & Platform Availability
Aftermarket tuning can affect factory powertrain warranty coverage — a dealer may decline a claim for a failure they attribute to the tune. Review your vehicle's warranty terms before tuning, and note that custom tune files are non-refundable.
EZ LYNK uses vehicle data — such as VIN, diagnostic data, and logs — to deliver tune files and support, and shares the relevant data with the technician you choose. Review EZ LYNK's official privacy policy for full details on how data is handled.
EZ LYNK / Auto Agent 3 is an active platform, and SPELAB currently offers the Auto Agent 3 tune packages for Ram, Ford, GM, and select Nissan diesel applications — contact SPELAB to confirm current stock and fitment for your truck. Certain platform operations may use tokens (platform licensing/credits); check with your technician or EZ LYNK for current details.
