Mazdaspeed Accessport & Accesstuner Updates/Improvements

Our Mazda Expert Group is extremely excited to announce the immediate availability of some major updates for the Mazdaspeed platform! New Accessport features, firmware improvements, and Accesstuner updates are all now available.

Accessport New Features

Windows 8.1+ Support for V2 Accessports

Original Version 2 Accessports are now compatible with Windows 8.1 and newer Operating Systems. Accessports must first be updated on a non-Windows 8.1 (or newer) machine. Once on updated firmware(1.6.8.55-10931), the Accessport will be compatible with those Operating Systems. This feature has already been available for the V2b and V3 Accessports.

User Customizable Start-up Screens

Users now have the ability to customize the Start-up Screen on their Accessport V3! Configuring this feature is straight forward, simply download Accessport Manager and follow the instructions in this knowledge base article: How To : User Customizable Accessport V3 Startup Screen

Readiness Monitor Reader Support

Version 3 Accessports now have the ability to scan for emissions readiness states whether installed or uninstalled. To read emissions readiness, simply select I/M Readiness in the Troubleshooting menu.

From there, you can view an extensive list of readiness monitors.

Restore OTS Maps

Accessible through the Tune menu, this feature allows users to restore OTS Maps from firmware without having to Uninstall the Accessport or download maps from cobbtuning.com/maps.

Accessport Firmware Improvements

All Gen2 ECUs will now see flash times up to 35% faster than before. A minimum threshold of 2500 RPMs has been added to Launch Control / Flat Foot Shifting as some customers were experiencing driveability issues when those values were set at unnecessarily low values. Engine Auto On/Off Detection has also received updates to integrate RPM detection in order prevent power cycling while driving. Finally, all V3 Accessport datalogs will now include a header with the Accessport’s firmware version, vehicle information, and map information.

Previous Map Delete Prompt (after flash)
