Cobb Tuning AccessPort for 135i 335i 535i and 1M (N54 Engine 2007-2010) - $895

The Cobb Tuning AccessPort is a flashing tool that installs performance software through the OBD port on your car. No other software is as easy to use and install! If you can program a TV remote, you're over-qualified to install this software. Just plug the AccessPort into the OBDII port under the dash, bring up the AccessPort onscreen menu, select from a variety of engine maps for your desired performance and install. It's that easy. The software is from COBB Tuning - one of the most accomplished software tuners in the business. The Cobb software replaces the conservative factory settings with different maps to make more power.

The AccessPort maintains the sophisticated control logic, refined engine response and excellent driveability of the stock BMW computer while providing impressive power gains and improved performance. Pre-loaded on the AccessPort are engine maps for 91 or 93 octane fuel, and a valet mode, with the capacity to hold up to 100 other tuning files! The AccessPort also saves your stock tune for you to revert back to factory settings at any time. It also has the the ability to download additional maps so that you can run various upgrades with the correct software tune. Additional tunes are available direct from Cobb through their AccessPort manager program (available for PC or OSX). Cobb also provides tech support.

In addition to the performance improvements, the AccessPort includes a variety of other useful tools -
+ performance measurements
+ data logging - up to 10 hours
+ fault code/DTC reading and clearing
+ check/verify performance modifications - measures 0-60 and ¼ mile times and can measure approximate HP

The AccessPort can display boost pressure, oil temperature, pedal position, load, individual cylinder timing, and other engine data channels with the Live Data feature.
