Accessport V3 ECU Upgrade

The COBB MAZDASPEED Accessport V3 (AP3-MAZ-002) is a comprehensive ECU upgrade solution for select Mazdaspeed vehicles, offering simple ECU flashing, customizable live gauges, and advanced datalogging capabilities. Its in-cabin mountable design features a large, full-color, higher-resolution screen capable of displaying up to six real-time parameters. The device offers extensive customization options, including bezel colors, gauge cluster layouts (race, street, dyno), and mounting preferences, powered by enhanced processing power, memory, and storage for faster flashing and ample map/log storage. Unlock hidden performance by replacing conservative factory settings with more aggressive calibrations. The Accessport supports a staged upgrade path with pre-loaded Off-The-Shelf (OTS) maps and custom mapping for various modification levels. Key features include a larger, full-color screen, customizable multi-gauge display, an in-vehicle mount with an on/off switch, and faster operation. It can also read and clear engine trouble codes, store up to 100 maps, and measure performance metrics like 0-60 mph times and quarter-mile ETs. Specifically for the MAZ-002, advanced tuning settings allow direct adjustment of features like launch control, flat-foot shift, and wastegate duty cycle from the Accessport itself. Launch control helps build boost for instantaneous acceleration off the line, while flat-foot shift allows keeping the throttle pinned during gear changes to maintain boost. The wastegate duty cycle can be adjusted between -50% to +10% to address underboost, overboost, or boost cut conditions (requires COBB OTS maps). Installation is straightforward with all necessary components included, and intuitive on-screen instructions guide you through vehicle identification and map selection. The Accessport can also be easily uninstalled, reverting the ECU to its original state. A critical warning states that installing this Accessport over anything other than OEM or COBB software may result in ECU/TCU failure; contact COBB Support if you have questions. The device is 50 State legal with CARB Executive Order D-660-116.
