The Cobb Tuning Accessport V3 is a multi-featured ECU reprogramming device for your 2008-2010 BMW 135/335/535. The Accessport V3 comes loaded with multiple maps for various setups (i.e. stock, turboback exhaust, etc.). It also allows for custom tuning by Cobb certified 'Pro-Tuners' or self-tuning with the purchase of Cobb's Street Tuner system and a laptop computer. Your BMW can easily be returned to stock at any time, as the Accessport V3 retains your stock base map. In addition, the Cobb Tuning Accessport V3 functions as a scan tool and on board data logger, diagnosing and clearing check engine lights (CELs) and logging numerous other vehicle parameters. The new larger color display with higher resolution allows the user to display up to 6 parameters at once. The display is fully customizable from the look, layout, and mounting solution (works with 1000's of standard mounting hardware). The Accessport V3 not only looks better, but is also upgraded internally with a faster processor as well as more memory and storage space. Best of all, the Cobb Accessport V3 installs via the under-dash diagnostic port, meaning you don't have to pick up a tool or even open your BMW's hood to install it.
Cobb's Accessport V3 Stage 1 map is designed for showroom stock cars, meaning you can boost your power and prepare for future modifications by simply plugging in the Accessport V3! As you add upgrades (i.e. exhaust or intake) you can download the appropriate map to get even more power from your BMW! If you already have an exhaust or other modifications, Cobb's Stage 2 map will eliminate the check engine lights (CELs) resulting from removing the catalytic converters, and maps with lowered wastegate duty cycles are available to reduce boost spikes on stock turbo BMWs and aftermarket exhausts. The Cobb Accessport V3 functions as a 'chip' for users working within the guidelines of the included maps, but it can also be tuned by a Cobb Protuner, or the end user using Cobb's optional Street-Tuner software for additional modifications including bigger injectors, turbos, etc. All the while, the Accessport retains the driveability and simplicity of a stock ECU.
