So, you've got a 2016 Subaru WRX and you're thinking about unlocking its true potential? Smart move! The Cobb Accessport is a game-changer for these cars, allowing you to remap the ECU and optimize performance. Let's dive into everything you need to know about using a Cobb Accessport on your 2016 WRX. We will cover the basics, benefits, installation, tuning, and even some troubleshooting tips. By the end, you’ll be well-equipped to make the most out of this awesome tuning tool.

Understanding the Cobb Accessport

The Cobb Accessport is essentially a handheld device that allows you to flash new maps, monitor engine parameters, and datalog your car's performance. Think of it as a mini-computer that plugs into your WRX's OBDII port, giving you unparalleled control over its engine management system. For the 2016 WRX, it's a particularly popular choice because it addresses some of the factory tune's shortcomings, such as inconsistent power delivery and less-than-ideal throttle response. It’s not just about adding more power; it’s about making the car smoother, more responsive, and more enjoyable to drive. The Accessport comes pre-loaded with several off-the-shelf (OTS) maps designed for various modifications, like intakes or exhaust systems. This makes it easy for beginners to get started without needing a custom tune right away. However, the real magic happens when you start exploring custom tuning options, which we’ll get into later. One of the best features of the Cobb Accessport is its ability to monitor a wide range of engine parameters in real-time. This includes things like boost pressure, air/fuel ratio, coolant temperature, and ignition timing. By keeping an eye on these values, you can ensure your engine is running safely and efficiently. Datalogging is another crucial function. The Accessport can record these parameters over time, allowing you to analyze your car's performance and identify any potential issues. This data is invaluable for custom tuning and troubleshooting. Furthermore, the Cobb Accessport is incredibly user-friendly. The interface is intuitive, and the device walks you through each step of the installation and tuning process. Even if you're not a seasoned mechanic, you should be able to get up and running with minimal hassle. Cobb also provides excellent documentation and support, so you're never truly on your own. In summary, the Cobb Accessport is a powerful and versatile tool that can significantly enhance the performance and driving experience of your 2016 Subaru WRX. Whether you're looking for a simple boost in power or a fully customized tune, the Accessport has you covered.

Benefits of Using a Cobb Accessport on Your 2016 WRX

Using a Cobb Accessport on your 2016 WRX unlocks a plethora of benefits that enhance both performance and driving experience. First and foremost, you'll notice a significant improvement in power and torque. The factory tune on the 2016 WRX is often conservative, leaving plenty of room for improvement. With the Accessport, you can flash a new map that optimizes the engine's parameters for increased output. This translates to quicker acceleration, better throttle response, and an overall more engaging driving experience. The Accessport isn't just about adding raw power; it also smooths out the power delivery. Many 2016 WRX owners complain about the stock tune's inconsistent power curve, which can make the car feel jerky and unpredictable. The Accessport addresses this issue by providing a more linear and predictable power delivery, making the car easier to control and more enjoyable to drive in daily situations. Improved throttle response is another major benefit. The stock throttle mapping on the 2016 WRX can feel laggy and unresponsive. The Accessport allows you to remap the throttle, making it more sensitive and responsive to your inputs. This results in a more connected and engaging driving experience, especially when accelerating from a standstill or maneuvering through corners. Beyond performance gains, the Cobb Accessport also offers valuable monitoring and diagnostic capabilities. The device can display a wide range of engine parameters in real-time, allowing you to keep a close eye on your car's health. This includes things like boost pressure, air/fuel ratio, coolant temperature, and ignition timing. By monitoring these values, you can catch potential issues before they turn into serious problems. Datalogging is another crucial feature. The Accessport can record these parameters over time, allowing you to analyze your car's performance and identify any anomalies. This data is invaluable for troubleshooting and custom tuning. For example, if you notice your car is experiencing knock, you can use the datalog to pinpoint the cause and adjust your tune accordingly. The Accessport also provides access to Cobb's extensive library of off-the-shelf (OTS) maps. These maps are designed for various modifications, such as intakes, exhaust systems, and intercoolers. This makes it easy to optimize your car's performance for your specific modifications without needing a custom tune right away. However, if you're looking for the ultimate in performance, a custom tune is the way to go. The Accessport allows you to work with a professional tuner to create a map specifically tailored to your car's modifications and driving style. This can result in even greater power gains and a more refined driving experience. In summary, the Cobb Accessport offers a wide range of benefits for your 2016 Subaru WRX, from increased power and improved throttle response to enhanced monitoring and diagnostic capabilities. Whether you're a seasoned enthusiast or a casual driver, the Accessport is a valuable tool that can significantly enhance your driving experience.

Installation Process

The installation of the Cobb Accessport on your 2016 WRX is a straightforward process that can be completed in under an hour. Before you begin, make sure your car is parked on a level surface and the ignition is turned off. You'll also want to gather a few basic tools, such as a laptop, a USB cable, and the Cobb Accessport itself. The first step is to download and install the Cobb Accessport Manager software on your laptop. This software allows you to update the Accessport's firmware, manage maps, and datalog your car's performance. You can download the software from Cobb's website. Once the software is installed, connect the Accessport to your laptop using the USB cable. The Accessport Manager will automatically detect the device and prompt you to update the firmware if necessary. It's important to keep your Accessport's firmware up-to-date to ensure compatibility with the latest maps and features. After the firmware is updated, you can disconnect the Accessport from your laptop and head to your car. Locate the OBDII port, which is typically located under the dashboard on the driver's side. Plug the Accessport into the OBDII port. The Accessport will power on and guide you through the installation process. The first step is to identify your car's ECU. The Accessport will automatically detect your car's year, make, and model, but it's always a good idea to double-check to ensure accuracy. Next, the Accessport will ask you to read the factory ECU data. This process can take several minutes, so be patient and avoid turning off the ignition or disconnecting the Accessport. Once the factory ECU data has been read, the Accessport will prompt you to select a map. If you're just getting started, it's recommended to choose one of Cobb's off-the-shelf (OTS) maps that is designed for your car's modifications. For example, if you have an aftermarket intake, you would select the OTS map that is designed for use with an intake. After you've selected a map, the Accessport will begin flashing the new map to your car's ECU. This process can also take several minutes, so be patient and avoid turning off the ignition or disconnecting the Accessport. Once the map has been flashed, the Accessport will prompt you to start your car. If everything went smoothly, your car should start up without any issues. The Accessport will then ask you to drive the car for a short period of time to allow the ECU to learn the new map. During this learning period, you may notice some slight changes in your car's performance. After the learning period is complete, your car should be running optimally with the new map. You can now use the Accessport to monitor your car's performance, datalog engine parameters, and make adjustments to the tune as needed. In summary, the installation of the Cobb Accessport on your 2016 WRX is a simple and straightforward process that can be completed in under an hour. By following these steps, you can unlock the full potential of your car and enjoy a more engaging and rewarding driving experience.
