EZ LYNK AutoAgent 2 Tuner with Custom Tuning by GDP

IMPORTANT: As tuning is customized to your vehicle, it will take 24-48 hours (2 business days) after connecting to your truck for GDP to deliver the tuning files to your EZ LYNK device. Tuner REQUIRES an iOS, Android or EZ LYNK Compatible Monitor (not included) to download and apply tuning.

The Future of Diesel Tuning Delivered Now

The revolutionary EZ LYNK AutoAgent is changing the way modern vehicles are tuned. Using cloud-based tuning and diagnostic delivery, wireless access point technology and the expert tuners at GDP, the EZ LYNK from GDP ensures that the provided tuning is perfectly suited to your truck. Further, because the tuner can be linked to any technician, should problems ever arise, information can easily be exchanged and parameters updated.

Power and Performance to Suit Your Needs

The GDP Tuning EZ LYNK can be configured in a variety of different ways to suit the specific operational requirements and the needs of your truck based on your current modifications. Whether you have a daily driver, a towing workhorse or a race truck, GDP provides a choice of tuning that fits you. Each unit includes "Switch-on-the-Fly" (SOTF) tuning with 4 custom power tunes and a stock power tune. A switch is REQUIRED for "on-the-fly" tune changing. See "Power Levels" for details.

Modern Simplicity

The EZ LYNK AutoAgent connects to your truck through the OBDII port and broadcasts a WiFi Access Point (WAP) which allows a wireless connection to the vehicle using any iOS or Android device. By launching the free EZ LYNK application on your device, engine data is seamlessly streamed and updated in real time on your screen. The AutoAgent also has the capability to re-flash vehicle system controllers with ECU profiles shared by technicians.

The Power of Knowledge

End users can conveniently share data-logs and other vehicle information to any technician with the touch of a finger without even leaving the driver seat. Datalogs can be quickly started and stopped from the main gauge display screen and bookmarks can be added to draw interest to specific points of a datalog if desired. A graphical web based datalog viewing solution will soon be incorporated into the EZ LYNK Cloud as well. A fully customizable user interface allows the end-user to create a gauge interface that suits their particular needs. Technicians can also create default PID configurations that are automatically loaded during a re-flash procedure to further assist in the troubleshooting and diagnostic process.

How It Works

Because this tuning is custom made for your specific needs and modifications, the GDP EZ LYNK will not come pre-loaded with tuning. Upon receiving the product, the EZ LYNK will need to be installed in your truck. Once the tuner is installed, GDP will be able to recognize the unit on their cloud based software. After this, you will send a profile to GDP Tuning that contains information about your truck such as tire size, injectors, and other modifications. GDP Tuning will then build the tuning specifically for your truck within 48 hours (2 business days).

GDP EZ LYNK Monitor (Optional)

Designed for Ease of Use

The Monitor System from GDP is designed to seemlessly work in sync with your EZ LYNK AutoAgent Tuner. Freeing up your mobile device, this monitor from GDP automatically connects to the AutoAgent and has the EZ LYNK app built in.

Dash Cam, Bluetooth and More

Not only will this monitor work effortlessly with the AutoAgent, it also features a built-in 1080p Dash Cam with WiFi and Bluetooth connectivity. The system also includes GPS Maps and other applications.

Mounting Choices

The kit includes a suction mount as well as a magnetic connector for easy removal when not in use.
