MAZDASPEED3/6 AccessPORT and AccessTUNER Updates Now Available!

Posted on 01 December 2010

COBB Tuning has just released significant updates to the AccessPORT firmware and AccessTUNER software for the first gen MAZDASPEED3 and MAZDASPEED6. AccessPORT enhancements include improved usability with four higher precision data monitors, a simplified menu system  and support for higher boost pressure data logging. AccessTUNER software improvements include a large selection of new tables, two important bug fixes and the addition of software auto-updating to simplify future software upgrades. These new additions continue to expand AccessPORT control of the ECU, letting users dig deeper into the OEM logic to extract even more power from the MAZDASPEED3/6, with unmatched simplicity, functionality, convenience and control!

AccessPORT Firmware The latest firmware update (version 1.6.3.2) is currently beta. The full release of this firmware will include map support for included Off The Shelf Maps and will be available soon. The changes in this beta firmware version include:

  • Boost pressure data logging limit has been increased to log pressures above 24PSI. Existing maps must be opened in the latest version of AccessTUNER, resaved and flashed back to the ECU to implement new feature.
  • Precision of the following monitors has been increased by another decimal place:
    • STFT (Short Term Fuel Trim)
    • LTFT (Long Term Fuel Trim)
    • MAF Voltage
  • Calculated Load data monitor display has been reworked to reflect the display shown in AccessTUNER (units displayed as Load Value instead of %)
  • Expose ECU Data feature allows the stock ROM to be backed up to a PC using AP Manager
  • Uninstall AccessPORT menu option moved back to the top menu level
  • Installed Stock Mode maps removed from firmware to reduce end user confusion regarding Uninstall vs. Installed Stock Mode
  • Demo Mode added to Settings Menu to enable AP navigation of all menus when powered up while not connected to ECU
