COBB Tuning is proud to announce new calibrations for BMW 135i, 335i and 535i turbocharged performance vehicles. In response to customer feedback, all BMW AccessPORT calibrations are offered with increasing levels of performance. Maps are now available in Drive, Sport and Aggressive configurations. This will simplify AccessPORT map selection and allow drivers to easily tailor their AccessPORT calibration to their specific driving style and performance needs. In addition, expanded throttle mapping options are available and each map includes improvements to power delivery. The latest firmware adds support for the latest ROMs discovered in the field.

Introducing BMW’s New Calibration Line-Up

COBB Tuning introduces a new calibration strategy for AccessPORT equipped BMW’s. This new calibration line-up gives drivers a choice of performance level within the Stage1 maps. Based on feedback from BMW AccessPORT users, one size does not fit all BMW drivers. In addition to offering four different throttle profiles to suit driver preference, COBB Tuning now offers three levels of performance to suit each drivers’ exuberance!

• Drive: The “Drive” calibration is made for the BMW enthusiast that is looking for just a little more power from their turbocharged BMW. These maps are ideal for spirited driving on your favorite back road or just a little more get-up-and-go around town. These calibrations retain the stock rev-limiter and also feature enhanced throttle smoothing for a more linear pedal feel and power-delivery.  For use with all premium pump fuels.
• Sport: The “Sport” calibration for your BMW AccessPORT is perfect for the demanding driver looking for that extra edge.
  These calibrations feature more boost pressure, a raised rev-limiter and removed top-speed limiters. Perfect for high-speed performance driving, but made specifically for all available premium fuels. The Sport maps are great around the autocross course or even for light duty at the racetrack.
• Aggressive: The “Aggressive” calibration is made for the ultimate in plug and play performance for the driver looking for the most from their car. With greatly increased boost pressure and no limiters to inhibit performance, these maps are made for the driver who wants the most that their BMW can deliver. These calibrations are designed for ultimate performance and it is highly recommended that 93 or greater octane is used.

All map performance levels and throttle profiles can be downloaded from the BMW AccessPORT Map Database.

Improved Throttle Mapping

All of our new AccessPORT calibrations feature improved throttle mapping for smoother power delivery and less, on/off feel. This will give your BMW a smoother, more linear feel while still giving that increase in power that enthusiasts desire. All AccessPORT mapping is now available with four different throttle calibrations to give drivers the throttle feel that best suits their driving style.

New Rom Support

COBB Tuning is always adding new support to the BMW AccessPORT. With this update, new ROM support is available for previously unsupported 2007-2009 BMW 135i, 335i and 535i vehicles including “is” and “xi” models. If you encounter a ROM that is not recognized by the AccessPORT, update to this latest firmware as we may have recently incorporated support for your ECU. If your ECU is not recognized using this firmware, please notify us promptly so that we can get you into the BMW AccessPORT family ASAP!

Bug Fix

The v300 maps revealed issues some customers have experienced, such as a possible limp mode when accelerating hard at higher rates of speed and slight surging at part throttle when the motor is cold. A torque limit threshold was adjusted to eliminate the potential limp mode and a fuel based load compensation was changed to smooth out the partial throttle drivability.

These new BMW performance calibrations and ROM support for your COBB Tuning AccessPORT are available for download or via our latest AccessPORT firmware update. To update your AccessPORT to the latest firmware, simply open the AccessPORT Manager application, connect your AccessPORT to your computer via the supplied USB cable, then click on the “Updates” menu icon and follow the on-screen prompts. These new features will be installed automatically. If you do not have AccessPORT Manager, you can find the download link for your free copy on our Support Page. To complete the update, flash one of the new v3.01 calibrations to your ECU. Using older maps with this update may cause poor performance or unexpected issues.
