COBB Tuning is happy to announce a new firmware update which includes new mapping for all automatic BMW 135i, 335i and 535i vehicles. These maps address the “rough shift” and poor shifting experienced by some users during full throttle driving and shifting at redline.

This update also adds more ROM support to the AccessPORT. Users that are currently supported via beta firmware can now update to this final release-version. If you are currently experiencing issues with a non-supported ROM, update your AccessPORT to this release to add full support.

To update your AccessPORT to 1.6.3.2-2309 firmware, simply plug the AccessPORT into your computer, launch AccessPORT Manager, and click the Updates button in the top icon bar. The AccessPORT will not need to be uninstalled to perform this update.

These newest calibrations are available right now from the COBB Tuning BMW Map Database. For more detailed information on maps and revisions, please consult the BMW Map Notes, Firmware Release Notes or call COBB Tuning at 1-866-922-3059.
