Cobb Audi S4/S5/SQ5 (B9/B9.5) AccessPORT V3

This is the COBB AccessPORT V3, a handheld tuning device specifically for the Audi S4, S5, and SQ5 models with the B9 and B9.5 chassis. If you're looking to unlock more performance from your turbocharged Audi, this device is designed to let you load custom maps and monitor your vehicle's data right from the palm of your hand. It's a popular way to get more power and responsiveness out of these cars without needing to permanently install a bulky computer module.

The AccessPORT V3 acts as a bridge between your car's engine computer and the performance you want. You can use it to flash updated engine control software, often called a 'map' or 'tune,' which can adjust parameters like fuel delivery, ignition timing, and boost pressure to make more power. It also has a built-in datalogging feature, allowing you to record various engine parameters while you drive. This is crucial for understanding how your engine is performing and for working with a tuner to create a custom map tailored to your specific car and modifications. The device itself is well-built and features a clear, color touchscreen display that makes it easy to navigate menus and view live data. It connects directly to your car's OBD-II port, so installation is straightforward – you simply plug it in, load your map, and you're ready to go. You can also use it to revert back to the stock map if needed, making it a versatile tool for both performance enthusiasts and those who want to keep their options open.

When you purchase the AccessPORT V3, it comes with everything you need to get started, including the device itself, a USB cable for connecting to your computer (for map updates and data transfer), and a windshield mount. Remember that loading a performance map will change how your car operates, and it's always recommended to consult with a professional tuner to ensure you're using the right map for your vehicle's specific modifications and to maintain engine health. This device is a key component for anyone serious about maximizing the performance of their B9/B9.5 Audi S4, S5, or SQ5.
