The v4.01 and v4.02 Off-The-Shelf maps for BMW N54 AccessPORTs have been promoted to General Release. The v4.01 and v4.02 maps now supersede v3.01 maps, which have been archived. COBB Tuning recommends upgrading to the latest version of the maps for optimal performance. These maps can be downloaded from the BMW AccessPORT Off-The-Shelf Map Database. For instructions on downloading maps, transferring them to the AccessPORT and flashing them to the BMW ECU, please see the Step-by-Step Map Download and Install Tutorial.
