The Accessport V3 is the world’s best selling, most flexible ECU upgrade solution for MAZDASPEED. Unlock power hidden within the vehicle by replacing conservative factory settings with more aggressive calibrations. Upgrade forever with off-the-shelf (OTS) calibrations for most bolt-on modifications. It’s the last engine management solution you’ll ever need.
Throw away your gauges!! The new in-cabin mountable Accessport V3 has a large, full color, higher resolution screen which allows you to monitor up to six parameters in real time. Fully customizable from the look (multiple bezel colors), layout (set up a race, street or dyno gauge cluster) and mounting options (choose from 1,000s of standard vehicle mounts). Of course, all of the great COBB tuning is included – with enough space for 100 calibrations.
This is your new Accessport – and maybe the last one you’ll ever need.
Advanced Tuning Settings: Dial in performance features such as launch control, flat-foot shift, and wastegate duty cycle, directly from the Accessport.
- Launch Control – Launch Control builds boost and generates instantaneous horsepower off the line. Once enabled, these settings can be adjusted before each flash of a compatible map.
- Flat-foot Shift – Keep the throttle on the floor during shifts and maintain boost between gears with this customizable RPM setting. Once enabled, these settings can be dialed in on the Accessport before each flash of a compatible map.
- Wastegate Duty Cycle – Adjust your wastegate duty cycle during flashes (-50% to +10%) to correct underboost, overboost, and boost cut conditions (requires COBB OTS maps).
Everything is included for the simple installation! Intuitive on-screen instructions identify your exact vehicle and available maps.
