***This package includes the hardware AND tunes required to tune your truck. If you are interested in using a friend's hardware, you will only be able to use a EZ LYNK single tune, and should visit the EZ Lynk TUNE ONLY product page.
Once you have placed the order for EZ Lynk tuning, you will receive a confirmation email and a second email stating your order has been PROCESSED. After you have received the email stating your order has been PROCESSED, please carefully read and follow the steps below.
1. Connect the Auto Agent to the OBDII port, and then turn the ignition to the RUN position.
2. Connect to the EZ Lynk WiFi.
3. Open the Auto Agent app.
4. You should see a prompt stating your VIN is set up to link with firstname.lastname@example.org.
5. Click the Lynk button.
6. Once linked, click the Main Menu button in the upper left corner. Click Vehicles, and then ECU Profiles.
7. You should now be able to see the available profiles shared to you.
If you manually linked your vehicle to CTT Tuning before your order has been processed, this will disrupt the sharing process. To access the tune files, unplug the Auto Agent from the OBDII port, and remove the vehicle from your Garage on the EZ Lynk app. Once the vehicle has been removed from your account, follow the steps above.
If you have modified the fuel system (injectors or injection pump) you will initially receive tuning for a STOCK fuel system. Please wait to flash the vehicle until you have received the proper tuning for those modifications.
If you have a 68RFE transmission, you MUST follow the transmission relearn procedure noted in the instruction manual, regardless if you’re installing transmission tuning or not!
If you have questions or complications with the EZ Lynk Auto Agent or the EZ Lynk app such as difficulty connecting to the Auto Agent or issues after a firmware update, please contact EZ Lynk at 877-207-5530 or email@example.com.

Gauge’s are able to monitored in multiple different views as seen in the pictures. All gauges can be set up for specific desired ranges, if in the range you are ok with the gauge will be green. When not, the gauge will be in a red warning state. If you pass through the warning state you will be able to set up defuel settings and the gauge will be white and make sure you do not hurt your truck.

Data logging Features:
End users can conveniently share datalogs and other vehicle information to any technician with the touch of a finger without even leaving the driver seat. Data logs 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 data log viewing solution will soon be incorporated into the EZ LYNK Cloud as well. 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.
30 Minutes of available Logging Time
Bookmarks for added notes when noting anything
Ability to e-mail data log file
Ability to Read Codes
Ability to Clear Codes
The AutoAgent connects to the vehicles via the OBDII-port and broadcasts a Wi-Fi access point (AP) which allows a wireless connection to the vehicle using any iOS device Or Android 5.0 and up smart devices. By launching the free EZ LYNK application on an iOS device, engine data is seamlessly streamed to the phone or other smart devices. The AutoAgent also has the capability to reflash vehicle system controllers with ECU profiles shared by technicians.
Technicians will quickly learn to appreciate the EZ LYNK Cloud where they can easily manage customers/vehicles and all the data associated with them (datalogs, engine profiles, vehicles information). Transferring engine profiles via USB connection, SD card or e-mail are now a thing of the past as technicians have the capability to share engine profiles with the click of a button to completely eliminate user-error from the equation.
On the other side of things, the end-user can conveniently share datalogs 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 the 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 reflash procedure to further assist in the troubleshooting and diagnostic process.
