Accessport V3 ECU Upgrade

The COBB Accessport V3 (AP3-MAZ-002) is the world's best-selling and most flexible ECU upgrade solution for your Mazda, designed to unlock hidden performance by replacing conservative factory settings with more aggressive calibrations. This handheld tuner offers a comprehensive package for ECU flashing, adjustable live gauges, and datalogging, all in one in-cabin mountable device. The Accessport V3 boasts a large, full-color, higher-resolution screen that can monitor up to six parameters in real-time. Its customization options extend to its appearance, with multiple bezel colors, and its layout, allowing for the creation of custom gauge clusters for race, street, or dyno use. The device also features increased processing power, memory, and storage for faster flashing and ample space to save all your maps and logs. It comes with interchangeable faceplates and an on/off switch for convenient in-vehicle mounting. Beyond basic tuning, the Accessport V3 provides advanced features for performance enthusiasts. These include adjustable live gauges to monitor boost or any other ECU data, the ability to store up to 100 maps from COBB's Off-The-Shelf (OTS) database or custom maps from a tuner, and the functionality to read and clear engine trouble codes. For performance measurement, it can track 0-60 mph times, 60-foot and ¼-mile ETs, and trap speed, alongside a programmable shift light. Specific to the MAZ-002 model, advanced tuning settings allow for direct adjustment of features such as launch control, flat-foot shift, and wastegate duty cycle. Launch control helps build boost for instantaneous horsepower off the line, while flat-foot shift allows drivers to maintain throttle during gear changes to keep boost levels consistent. Wastegate duty cycle adjustments can be made to correct underboost or overboost conditions. The device is also 50-State Legal, carrying a California Air Resources Board (CARB) Executive Order (EO) number D-660-116. Installation is straightforward with intuitive on-screen instructions, and reverting the ECU to its original settings is equally simple with the Uninstall option. The Accessport V3 is compatible with the AP Manager software for PC/Mac, facilitating map management, datalog downloads, and firmware updates. It is important to note that installation over anything other than OEM or COBB software may result in ECU/TCU failure; users should contact COBB Support if they have any questions. This Accessport is exclusively for USDM (United States Domestic Market) vehicles.
