⚙️ Key Components & Recommendations
SOTF Switch (Shift-On-The-Fly):
The SOTF Switch is needed to correctly run SOTF tunes.
Without the switch, your tune will default to the lowest power level. Installing the switch allows you to adjust power levels instantly and maximize your vehicle’s performance.
TCM Tuning (Transmission Control Module):
TCM Tuning increases the line pressure in your transmission so it can handle the added engine power from the tunes.
We highly recommend TCM tuning for anyone with a 68RFE transmission that plans on running anything more than a tow tune.
IMPORTANT: Please specify if you have any transmission modifications when ordering TCM Tuning!
✅ What’s Included & System Features
Smartphone Required: You MUST HAVE A SMARTPHONE (iOS or Android) to download and install tunes.

Unlock Cable: Includes the required unlock cable for 2018+ Cummins or Nissan pickup trucks.

Emissions System Management:
DPF / CAT / DOC / SCR: The EZ LYNK is a delete-capable tuner. These components must be removed.
EGR: The tune will deactivate the EGR system. The EGR can be left installed (but unplugged) or completely removed with the included delete kit (recommended).
DEF: Diesel Exhaust Fluid is no longer required. The tank can be unplugged or removed.
Check Engine Light / DTCs: Prevents emission-related trouble codes. The system will still alert you to other non-emission vehicle issues.
Fuel Mileage: Expect significant fuel mileage gains after removing emission restrictions (e.g., from 13-14 MPG to a combined 18-19 MPG). Results may vary with driving habits and modifications.
️ General Installation Guide

Living up to the brand name, the EZ LYNK installation process is simple.

Download the App: Download the “AutoAgent” app from the App Store (iOS 8+) or Google Play Store (Android 5+).

Key in ‘Run’ Position: Turn your key to the ‘Run’ position without starting the engine. For push-to-start vehicles, press the button twice.
Plug in the AutoAgent: Plug the AutoAgent device into your vehicle’s OBD-II port. A blue and green light indicates it has booted correctly.
Connect via WiFi: Open your smart device’s WiFi settings and connect to the “EZLYNK_####” network. (The AutoAgent 2 also supports Bluetooth).
Open the App: Navigate back to the AutoAgent app. You should now see your vehicle’s gauges.
Lynk Your Vehicle: A message will appear asking you to “lynk” your vehicle to your technician’s account. Follow these prompts to connect.

Here you can view the list of available tunes.
Tap to download your desired profile, then tap ‘Install’ to flash your vehicle.
⚠️ SPECIAL INSTRUCTIONS (Jeep & Ram 3.0L EcoDiesel / 2.8L Duramax)

YOU MUST FLASH THE TRUCK BEFORE INSTALLING ANY OTHER HARD PARTS! FAILURE TO FOLLOW THESE STEPS MAY CAUSE ISSUES.

Preparation
Hook up a Battery Charger: Connect a battery charger set to a low charge (e.g., 10A). New ECUs are very sensitive to voltage drops during flashing. This step is critical.
Connect Bypass Cable: If you are flashing a 2018+ Cummins, a 3.0L Jeep, or a Ram 1500 EcoDiesel, you must connect the Bypass Cable during the flash process.
Flashing Steps
Get the EZ LYNK Auto Agent.
Tune Before Removing Parts: Tune the truck before you remove any hardware. This ensures you are not stranded if you run into an issue.
Connect the Battery Charger. (Crucial Step)
Download the App & Create an Account.
Plug in the EZ LYNK & Bypass Cable (if required).
Connect to the Auto Agent via WiFi and follow the prompts to link your vehicle. Let your technician know when you are linked so they can send the tune files.
Flash The Correct Tune Files (KEY STEP):
Navigate to ECU Profiles.
FIRST, you must flash the RESET or “FLASH FIRST” file. The exact name will be similar to:
Jeep: 68270625AG_1_MUST_FLASH_FIRST
Ram 1500: #0 – MUST FLASH FIRST THE VERY FIRST TIME
Colorado/Canyon: [YEAR]_2.8_RESETFILE
Flashing this file should take about 7 minutes. If it flashes instantly, it has not worked.
After the flash completes, fully disconnect the EZ LYNK and disconnect the vehicle’s batteries for 10 minutes.
Reconnect everything, and now you can flash the desired power level tune (e.g., …_50HP_ECONOMY_…).
Policies & Disclaimers
Return Policy: Since the EZ LYNK provides VIN-specific custom tuning, there are NO RETURNS or REFUNDS.
Processing Time: Custom programming may take up to 1-2 business days. Once your order has been submitted, it cannot be cancelled.
