EZ LYNK Auto Agent 3: Check Coverage Before You Check the Price

Your engine and your model year pick the tune. The generation number printed on the box does not.

Three EZ LYNK delete tune packs sit on this page, and they land on three separate platforms: GM Duramax, Nissan Titan, and Ford Powerstroke. Each one is built against a specific VIN and a specific set of hardware, which is why the year range decides more here than any spec on the reader itself.

Find your platform below, put your year next to it, and most of the version argument stops mattering.

Is the Version Number Actually the Question?

Not really. A tune is written against one engine's hardware and one control module, and neither of those is settled by which generation of reader is sitting in your glovebox. The number on the case describes the case. Your year and your engine decide whether a calibration exists for you at all.

The same badge covers more than one set of hardware

Diesel platforms do not hold still, and the nameplate on the fender is the last place that shows up.

The LZ0 Duramax 3.0L turbo diesel is the second generation inline-six turbo diesel over the previous LM2.^[1]

That is two generations of hardware wearing one displacement figure. The LZ0 handles its exhaust gas recirculation with a high-pressure circuit that is not cooled.^[1]

Even the brain moves. On the latest 2.8L LWN Duramax, the engine runs a new E71 electronic control module, and it can also use the GM Powered Solutions DMEFI-1 controller instead.^[2]

So the question "will the Auto Agent 3 work on my truck" is really a question about whether somebody has written a calibration for your engine, in your year, and put it on a shelf. That is a much smaller question, and it has a yes-or-no answer.

What a calibration is actually reaching for

Under the hood, a modern diesel is a set of very fast decisions made a few thousand times a minute.

Combustion in a diesel expands high-temperature, high-pressure gas, which moves the pistons and turns chemical energy into mechanical energy.^[3]

The fuel side of that is common rail, and common rail exists precisely so the calibration can be exact. A high-pressure rail feeding each injector independently gives precise control over fuel injection timing and quantity.^[4]

The air side is the turbo, and on a variable geometry unit it is doing three jobs at once. A variable geometry turbo aids engine braking, exhaust gas recirculation and thermal management across engine speeds and loads.^[5]

Change what comes off the truck and you have changed the assumptions behind every one of those decisions. Which is the whole reason a delete tune is a custom file and not a download.

What We Stock, and What Each One Fits

Three packs, three platforms, no overlap between them. Each one is written for the hardware on that specific truck, so the year range under each heading is the part worth reading twice. Pricing across the three starts at $899.00.

EZ LYNK AUTO AGENT DPF Delete Tune | Lifetime Support Pack | GM/Chevy Duramax 2011-2016

The EZ-Lynk DPF Delete Tune with Lifetime Support Pack lets you run your 2011–2016 GM 2500–5500 Duramax with deleted DPF (Diesel Particulate Filter) and EGR (Exhaust Gas Recirculation) components, so there are no codes, no regen, and no warning lights.

It's a DSP5 tune for the EZ-Lynk Auto Agent 3.0 and is also compatible with the Auto Agent 2.0.

DSP5 means the tune carries five power levels on the device at once, and you shift between them on the fly using a rotary switch (a switch is required and not included), so no laptop is needed while you drive.

The five levels run 20hp, 40hp, 60hp, 80hp, and 100hp, with GM trucks receiving the 150hp top-level tune.

After you buy, we email a form to collect your tuner serial number, vehicle VIN, and any modification details, and we build your custom tune from that information.

The Duramax pack runs $899.00 - $999.00.

EZ LYNK AUTO AGENT DPF Delete Tune | Lifetime Support Pack | Nissan Titan 2016-2019

The EZ Lynk DPF Delete Tune for 2016–2019 Nissan Titan is a Lifetime Support Pack with a CSP5 tune that lets you run your Titan with deleted DPF (Diesel Particulate Filter) and EGR (Exhaust Gas Recirculation) components — no codes, no regen, no warning lights.

This is a tune pack for owners who already have an EZ-Lynk device.

CSP5 means the tune carries five power levels on the device at once, and you shift between them on the fly with a rotary switch (the switch isn't included).

The five levels run 20hp, 40hp, 60hp, 80hp, and 100hp […].

Fitment covers 2016, 2017, 2018, and 2019 Nissan Titan, and the tune is compatible with both the EZ-Lynk Auto Agent 3.0 and Auto Agent 2.0 hardware.

The Titan pack is $899.00.

EZ LYNK AUTO AGENT DPF Delete Tune | Lifetime Support Pack | Ford 2008-2022

This DPF Delete Tune for Ford Powerstroke is the Lifetime Support Pack with DSP5 tuning for the EZ-Lynk Auto Agent 3.0, and it's compatible with the Auto Agent 2.0 as well.

It lets you run your Powerstroke with deleted DPF (Diesel Particulate Filter) and EGR (Exhaust Gas Recirculation) components, with no codes, no regen, and no warning lights.

The five levels are 0HP with emissions deleted, +50HP, +100HP, +150HP, and +200HP.

Fitment covers the 2008-2019 Ford Powerstroke F250-F550 and the 2018-2020 Ford 3.0L.

Specify your year and engine on the vehicle info form and we'll build the correct tune.

The Powerstroke pack runs $899.00 - $1,425.00.

How to read those year ranges

A range is a promise that a calibration exists for the trucks inside it. It is not a promise about trucks that merely look similar, and that distinction is where most of the disappointment on this kind of purchase comes from.

Read yours the boring way. Find the range your model year falls inside, check the engine named beside it, then stop. If both match, you are covered. If either one does not, the answer is no, and no amount of forum reading is going to change it.

That is also why the year and the engine get asked for on the form rather than read off the order. Two seconds of typing beats rebuilding a file later.

What a range cannot tell you

A year says nothing about what has already been done to your truck. A stock engine and one running a different turbo with bigger injectors are two different calibration problems, and that is exactly what the modification section of the form is there to catch.

Which Pack Should You Buy?

Your platform picks it for you. Find the heading below that matches your engine and your year, and you have your answer. The decision that is genuinely yours sits one step further on: whether you are wiring in a rotary switch, and which power level you want to live on.

On a 2011 through 2016 6.6L LML Duramax

On a 2011 through 2016 6.6L LML Duramax, the Duramax pack is the one to buy.

Start low and work up over a few passes rather than reaching for the top rung on day one. Your fuel system and your right foot both need a chance to learn the truck again.

On a 2016 through 2019 Nissan Titan

The Titan pack is the only one here that fits.

There are fewer decisions to make on this one, which is worth something on a Friday afternoon. Get your year and your serial number together and you are most of the way to ordering.

On a 2008 through 2018 6.7L or 6.4L Powerstroke

On a 2008 through 2018 6.7L or 6.4L Powerstroke, the Powerstroke pack is the one.

If the hardware is already off the truck and you are not chasing a number yet, run it on the lowest setting until everything else is settled. Then climb.

Sort the switch question out first

This is the one thing worth deciding before you order rather than after, because it changes which file you end up flashing at the end of the job. Wiring a rotary switch in is not difficult work, but it is a lot easier to plan for than to retrofit around a truck you have already put back together.

Running the Coverage Check Before You Pay

Two minutes and you will know where you stand. You need four facts in front of you — year, engine, what has already come off the truck, and the serial number on your reader — and you need them before the card comes out, not after.

The four facts, and why each one is asked for

Year and engine settle coverage. That is the yes-or-no.

The modification history settles the file. A truck that already has a turbo-back and no EGR cooler is not the same calibration problem as a stock one, which is why we ask for it in writing rather than guessing from the order.

The serial number ties the tune to your reader rather than to somebody else's. And your VIN is what the file is actually written against.

When your year sits on the edge

Year ranges have edges, and edges are where returns come from. A truck built late in a model year can carry the next year's hardware, and no listing anywhere solves that for you.

Ford is the platform to be careful with here, because two different engines and a long run of years sit inside one range. That is exactly why the vehicle info form asks for both.

Not sure which side of a range your truck falls on? Call (888) 830-2588 before you order. We would rather spend four minutes on the phone than process a return on a file that was never going to load.

What the Factory Hardware Is Doing While It Is Still Bolted On

It is running a cycle you mostly cannot see. The filter collects soot, the computer decides when it has collected enough, and then the engine burns it out by deliberately raising exhaust temperature. Every part of that is a calibration decision, which is why removing the hardware without a tune goes badly.

The filter fills, and the computer lights it off

The Duramax engine is equipped with a Diesel Particulate Filter (DPF) that will filter or trap particulates.^[6]

The DPF is under the vehicle in the exhaust system.^[6]

It is not a service item in the normal sense. The DPF will clean itself as part of normal operation.^[7]

What triggers that is the engine computer watching a running tally. Hours of engine operation and miles driven are monitored by the Engine Control Module (ECM).^[8]

That tally is what decides it. When a cleaning is needed, the engine computer will initiate a cleaning action by warming the exhaust gas temperature.^[6]

There is a manual path as well, but it is gated. Manual regeneration can only be used when the DPF has become at least 90% full.^[6]

Why idle time is the enemy

This is the part that catches people out in the pits, where a truck spends far more time sitting than it does moving.

Extended idle should be avoided because the DPF system is not capable of self cleaning at idle.^[6]

That is not a warning about wear. It is a straight statement that the cycle physically cannot run, because the exhaust never gets hot enough to burn anything.

Short-run use has the same problem. If the vehicle is used for numerous short trips or extended slow-speed operation, the engine computer may not be able to adequately heat up the exhaust system to clean the DPF effectively.^[6]

And when conditions are wrong, the cycle does not simply take longer. Under certain conditions, such as idling or very short trips, the self-cleaning process has less efficiency and cannot be completed.^[8]

A filter that never finishes a cycle is a filter that only ever fills up. That is the trap a lot of sled-pull and event trucks fall into without ever doing anything wrong.

What it feels like from the seat

You can hear a cycle start if you know what you are listening for.

During self-cleaning there will be a change in the exhaust sound and engine idle speed.^[9]

Your nose gets there before your ears sometimes. A burning smell and a reduction in fuel economy may be noticed too.^[9]

There is a consumables bill attached to all of it, too. Damage can occur to the DPF components if the required Ultra Low Sulfur Diesel (15 ppm sulfur maximum) fuel and either CJ-4 or CK-4 engine oil are not used.^[7]

We get it — none of that is why anybody bought the truck. But it is the behaviour a delete tune has to take over cleanly, and it is why the file has to be built for your engine rather than pulled off a shelf.

Getting the Tune Onto the Truck

The order matters more than the tools do. Tune first, hard parts second, with a charger on the batteries and a phone that can see the reader. Get that sequence right and the job is a quiet afternoon. Get it backwards and you have a truck on stands waiting on a file.

What to have within arm's reach

Nothing exotic, and nothing you have to order in. A phone or tablet, a battery charger long enough to actually reach the terminals, and an afternoon where nobody needs the truck.

Do the software side at the kitchen table rather than on your back under the dash. Go to the App Store or the Google Play Store and download the EZ-Lynk Auto Agent App.^[10]

Make the account there too, while you have signal and both hands free. The number of jobs that stall because somebody is trying to confirm an email address from under a dashboard is higher than you would think.

Tune first, hard parts second

This is the single most important line in our own instructions, and it is the one people skip.

Install delete tune BEFORE installing your Exhaust & EGR delete parts.^[10]

Tune your truck before removing the hard parts.^[10]

The logic is not complicated. If the flash gives you trouble, you want a truck that still runs while you sort it out — not a workhorse in pieces on the floor with the exhaust already in the scrap pile.

Put a charger on it before you flash

Voltage is the quiet killer on this job, and it catches brand-new batteries as often as tired ones.

The new ECM's are very sensitive to voltage and the flash can fail if the voltage drops too low.^[10]

So hook up a battery charger and set it to a 10A charge.^[10] Ten minutes of setup before you start beats an interrupted flash.

Plugging in and getting linked

Plug the EZ-Lynk into your OBDII port under the dash.^[10]

Then connect your phone or tablet to the Auto Agent over wifi.^[10] Once you are connected you can open up the app, and the Auto Agent should detect your VIN number and recognize the connection.^[10]

Do not start pulling fuses if that screen comes up empty. If your device is not auto linked, or it prompts you to connect to a technician, review the support article covering exactly that.^[11]

Which file to pick, and the one you cannot undo by accident

Select ECU Profiles from that screen, this is where your delete tunes are stored.^[10]

That list is where the switch decision from earlier comes back. The tune that has "SOTF" is the Shift on the Fly tune, and you only use that file if you install the DSP5/CSP4/CSP5 switch.^[10]

One more thing worth knowing before you start, because it confuses people mid-job. You cannot overwrite an Engine Tune with a TCM Tune and ViceVersa.^[10]

The good news? The reader does not have to live in the dash afterwards. It only needs to be plugged in while you install your tunes or make changes.^[10]

What actually slows an order down

Not shipping. Not the file. The form.

Every one of these packs is built from what you send back on the vehicle info form, and nothing starts moving until it lands in our inbox. That is the whole bottleneck, and it is the one part of this that sits entirely on your side of the fence.

Fill it in the day it arrives and the job collapses into a single evening. Leave it in a tab for a week and you have added a week, with a truck sitting there and nothing wrong with it.

One field is worth double-checking before you hit send. The serial number wants to come off the reader itself rather than off the carton it shipped in.
