Cobb 2008-2010 BMW 135i / 335i / 535i / 2013 BMW 335iS AccessPORT V3

The COBB AccessPORT V3 is a handheld tuning device that lets you adjust your BMW's engine computer to get more power and better responsiveness. It's designed to work with a range of BMW models, including the 135i, 335i, 535i, and Z4, allowing you to tailor the engine's performance to your liking. This device lets you load different engine maps, or 'tunes,' which can change how your engine behaves, often resulting in improved acceleration and a more engaging driving experience.

This V3 AccessPORT features a larger, brighter, and more responsive touchscreen display compared to older versions, making it easier to navigate menus and view real-time data. It also includes an updated USB port for faster data transfer and firmware updates. The device allows you to flash custom maps from tuners like COBB directly into your car's ECU. You can also monitor live engine data, read and clear trouble codes, and even perform diagnostics, all from this single handheld unit. It's a well-built tool that gives you significant control over your vehicle's performance characteristics.

When you get the AccessPORT V3, it comes pre-loaded with a stock map for your specific vehicle. You can then choose to load a COBB Off-The-Shelf (OTS) map, or if you're looking for something more specific, you can get a custom tune from a COBB-certified tuner. The device is designed to be a direct plug-and-play solution, meaning you don't need to permanently modify your car's wiring harness. It's a popular choice for BMW owners looking to unlock the full potential of their turbocharged engines.
