COBB Tuning has just released an AccessPORT firmware update for the 2002-2003 and 2004-2005 Subaru WRX (AP-SUB-001). This update repairs two minor bugs with the AccessPORT, adds new functions and streamlines  the menu screens. This update supports v2 and v2b units, meaning that both versions  use the same firmware release: 1.6.0.0-12994. In addition, all “BETA” versions have been consolidated into this update.

The bug fixes in this release resolve the AP slowdown associated with extensive use  as well as the ECU identification errors that have been occurring in the field.

Additional data monitors (Absolute Pressure, Barometric Pressue and Fuel Economy) have been added to the v2 AccessPORT to match the data monitors available on v2b. The “About” screen on both v2 and v2b has been simplified for easier interpretation and support and the “Change Map” feature has been updated for both units to give an explanation for any gray-out “locked-out” maps.

This update is available immediately through AccessPORT Updater and requires no other updates to maps or tuning software be performed. Further information can be found on our Firmware Information Page.
