The Cobb AccessPORT is a user friendly and extremely powerful ECU Flash Tuner for BMWs N54 Twin-turbo engine. Within each AcessPORT for your BMW are ECU programs that you, the end user can flash and simply replace the boring conservative factory fuel, boost and spark settings with far more performance oriented calibrations that result in dramatic gains in power, torque and response while still maintaining a high degree of safety for your engine.

This flexible solution allows you to choose at your convenience what map you would like to extract the best performance from your BMW.

The latest version of the AccessPORT even allows for custom mapping by COBB authorized tuning centers.  Typical performance gains from the Cobb AccessPORT are increases of 30% peak horsepower and an amazing 38% increase in peak torque over stock! You can even gain more when used along with other performance modifications!

The AccessPORT is not a Piggyback computer, but is a tool along with performance software that is used to "flash" new ECU maps into the factory computer. This allows for a high degree of safety and a very elegant solution; there will be no added devices to your vehicle's ECU or wires to contend with. Truly great technology that is easy to update and easy to use by anyone, and installation is a breeze: literally requiring only minutes of time.

Important Note - Occasionally an "Unrecognized ROM" will be discovered during the AccessPORT Install process. If an "Unrecognized ROM" is encountered, the user will be prompted to dump the ROM using the onboard Dump ROM tool built into the AccessPORT. Simple step-by-step instructions for dumping an "Unrecognized ROM" can be found here. The ROM is then emailed to COBB Tuning and incorporated into the firmware. COBB Tuning will make every effort to incorporate these new ROMs as quickly as possible. This process can take up to five business days. See the "Supported ROMs" Tab above for a complete list on what ROMs are currently supported.
