Limited Support Package. Our limited support packs give you access to all tuning compatible with your vehicle for 4 weeks. This is convenient if you’re seeking a single tune to install on your vehicle. Once the 4 week expires the tune that is currently in your truck will remain. Upgrading to Full support will give you access to all tuning and software updates indefinitely.

Full Support Package offers unlimited flashes and basic tune revisions on ALL TUNES. You’ll receive automatic tune updates so that you can take advantage of the progress that we make and enjoy the timelessness of the EZ LYNK AutoAgent.

The SOTF Switch is needed to correctly run SOTF tunes. Without the switch installed, your tune will default to the lowest power level. Installing the switch will allow you to adjust power levels and maximize your vehicle’s performance instantly.

TCM Tuning will increase the line pressure in your transmission so it can keep up with all the added power your engine will be producing from the tunes. We highly recommend TCM tuning to anyone with a 68RFE that plans on running anything more than a tow tune. Please specify if you have any transmission modifications when ordering TCM Tuning!!

Installation Steps

Living up to the brand name, EZ LYNK has made the installation process simple. We’ve broken down each step and provided some valuable information that will help you understand how your AutoAgent works.

Step One: Download & Install the AutoAgent App
The AutoAgent app is available for most smart devices. It requires iOS 8+ or Android 5+ to operate. You can download the iOs app here and the Android app here.
Step Two: Create an Account
From the AutoAgent app, select ‘create an account’. You will need to verify that your email address is valid upon creation. Dealers should always create an account for the end-user or use the account that the end-user has already created.
Step Three: Place Your Key in the ‘Run’ Position
Turn your key all the way over without starting the vehicle. This will boot your vehicle’s engine computer allowing the AutoAgent to communicate with it. If you have a push-to-start vehicle, you should press the Start button twice.
Step Four: Plug the AutoAgent into your OBD-II Port
With the key in the ‘Run’ position, plug your AutoAgent into your vehicle’s On-Board Diagnostics port. You can verify that it has booted correctly when you see that a blue and green light are illuminating from the device.
Step Five: Connect to your AutoAgent from your Smart Device
Navigate to the WiFi settings of your smart device and select the ‘EZLYNK_####’ network. A check mark will appear next to the network name when you have successfully connected. The AutoAgent 2 also allows you to connect via Bluetooth.
Step Six: Open the AutoAgent App
After you’ve successfully connected, you can navigate back to the AutoAgent app. You should now be able to see your vehicle gauges.
Step Seven: Lynk your Vehicle
When you purchase from Unlimited Performance or an authorized dealer, your vehicle will be AutoLynked. If your smart device has cellular data, you will notice that a message has appeared asking you to lynk the vehicle. Follow these prompts to connect your vehicle with your mechanic/technician. If your smart device does not have cellular data, you will need to connect to an internet available network and re-open the app to complete the lynking process.
Step Eight: Program Your Vehicle
After completing the lynking steps you are ready to flash your vehicle.
Navigate to > Vehicle > ECU Profiles. Here you can view the list of tunes or ECU profiles that are available to you.
Tap the button to download your desired ECU profile, followed by the ‘Install’ button to flash your vehicle. The app will guide you through the flashing procedure.
(When using a smart devices without cellular data you will need to switch to an internet available network to download the ECU profile, then back to the EZ LYNK network to install the ECU profile.)
