Performance Module is designed to optimize fuel pressure and boost in the lower RPM band where most daily driving is spent.

Because modules do not download over the ECM like a tuner, once the module is unplugged it is untraceable. Essentially, a diesel module is telling a lie to your trucks ECM in order to get the desired output.
The module manipulates the signal from the sensor(s) and provides a different one to the ECM. And with a voided warranty, you will be stuck footing the bill.Ī diesel module (sometimes called a chip) plugs in between your trucks ECM and one or more of the engine sensors. Because the truck is now operating outside of the safety parameters designated by the manufacturer, you are more likely to encounter costly part failures. Tuners are capable of creating significant power gains for your truck, and sometimes even fuel gains. Be cautious though – even if you set your tune back to stock, the dealership is able to see that changes were made. Other tunes are installed via a computer at your local diesel shop (these are much more custom tunes). Most of these tuners also come with the ability to download the stock tune back to your ECM. Some companies sell handheld tuners that come preprogrammed with one or more tunes.
Once the download is complete, there is no need for the tuner to remain plugged in. Tuners are typically plugged into the OBD-II port under the steering wheel and then the tune is downloaded to the ECM. This overrides the trucks original ECM and voids any existing warranty. For example, your trucks ECM knows to shut down the engine or go into reduced power mode if the engine hits a certain temperature.Ī diesel tuner, or programmer (they are the same thing), downloads a new set of parameters and a new lookup table to your trucks ECM. In addition to knowing how much fuel and air to add, a trucks ECM is programmed with minimum and maximum parameters for each of the variables. The ECM uses a lookup table to determine how much fuel and air to add based on the values of the other variables. The ECM knows how much fuel and air to add based on how the ECM is programmed (often referred to as “tuned”). These variables in combination with throttle input determine how much fuel and air the ECM will add to the engine. The ECM is constantly monitoring things like engine temperature, exhaust gas temperature (EGT), coolant temperature, injection timing, fuel rail pressure (FRP), manifold absolute pressure (MAP), revolutions per minute (RPM), and much more. Simply put, the Engine Control Module (ECM), is the brain of the engine.
To understand how tuners and modules are different, we will first learn about what an Engine Control Module (ECM) is. People in diesel forums seem to use these terms interchangeably, and when you ask your buddy about it he frantically changes the subject to secretly cover the fact that he has no idea either.įear not – the team at Dr. You want to make an easy modification to your diesel truck, so you start doing your research and come across tuners, programmers, chips, and modules. What is the difference between a diesel tuner and a diesel module?
