Couldn't load pickup availability
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 on it. 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. If you would rather have the device and the tuning together, we sell DIESELR tune files for the platforms below, and we can load a support pack for your truck.
If you are unsure which you need, call us at +1 (877) 223-5018 before ordering. It is a short conversation and it avoids buying the wrong thing.
Platforms we tune
- Ford Powerstroke — 6.4L (2007.5-2010), 6.7L (2011-2026), 3.0L (2018-2019)
- RAM Cummins — 6.7L (2010-2024)
- GM Duramax — LMM, LML and L5P
- Ram EcoDiesel — 3.0L (2014-2019)
- Nissan Titan XD — 5.0L Cummins (2016-2019)
The device itself covers a wider range than this. The list above is what DIESELR writes tune files for.
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
