EZ Lynk Auto Agent 3 Tuner - Blank

The EZ Lynk Auto Agent 3 is a cloud-based tuning and monitoring device for diesel trucks. It plugs into the OBDII port and pairs with the EZ Lynk app on a phone or tablet, so tune files, live data and diagnostics are all handled from the driver's seat. No laptop, and no trip to a shop to change a tune.

This listing is the blank device: hardware only, with no tune files loaded. Tuning is purchased separately.

What it does

• Loads and swaps tune files over the air through the EZ Lynk cloud
• Displays live engine data — coolant temperature, boost, throttle position, injection timing, transmission temperature and exhaust pressure
• Reads and clears diagnostic trouble codes
• Supports more than one vehicle from a single device, with an additional support pack per vehicle
• ELD certified as an electronic logging device

What "blank" means

A blank Auto Agent 3 ships with no tuning. That is the right choice if you already have a tuner you work with, or if you want to buy the hardware now and decide on tuning later. 

Platforms we support

• Ford Powerstroke — 6.4L (2007.5-2010), 6.7L (2011-2026), 3.0L (2018-2019)
• RAM Cummins — 6.7L (2010-2024)
• GM Duramax — 6.6L L5P (2017-2025)
  

The device itself covers a wider range than this. 

Cables

The Auto Agent 3 connects through a vehicle-specific cable, and the correct one depends on your truck. Later RAM 2500/3500 trucks need the SGM adapter cable, the Nissan Titan XD uses the Titan cable, and heavy-duty applications use a 9-pin or 6-pin Deutsch cable. We stock the full EZ Lynk cable range — check the fitment on the cable listing, or call and we will confirm it.

Who it suits

• Owners running a custom tuner who need the hardware but not the files
• Custom tuners developing and distributing files across platforms
• Fleet operators managing several trucks from one device and one account
