This is the Cobb AccessPORT V3, a handheld engine tuning device specifically for your 2011-2014 BMW 335i, 335xi, or 2011-2013 BMW 135i. It's designed to let you access and modify your car's engine control unit (ECU) to unlock improved performance and responsiveness. If you're looking to get more out of your turbocharged BMW, this is a popular way to do it.

The AccessPORT V3 allows you to flash pre-loaded maps directly to your car's ECU, or you can use it to load custom maps created by professional tuners. It also functions as a real-time data display, letting you monitor various engine parameters like boost pressure, RPM, and temperature right from the device. This is incredibly useful for understanding how your engine is performing, especially if you've made other modifications. The device itself is well-built and features a color touchscreen for easy navigation. It's a direct replacement for your stock ECU calibration, meaning you don't need to permanently alter your car's wiring.

When you purchase the AccessPORT V3, it comes with a selection of off-the-shelf maps tailored for different fuel grades and modification levels. You can also easily switch back to the stock map if needed. For those looking to fine-tune their setup further, the AccessPORT V3 is compatible with custom tuning services, allowing for highly specific adjustments to match your car's unique modifications and your driving style. Make sure to check the specific map notes for the best results with your vehicle's current setup.
