• Realtime Tuning: Make changes to the map in real-time, even while the engine is running. Speeds up tuning and allows quick adjustments to features like Launch Control, Flat Foot Shift, and map switching. (Coming soon for DIT Subaru Forester XT models!)
• Adjust Idle: Modify engine idle on-the-fly to accommodate aftermarket accessories such as lightweight flywheels and upgraded cams. Separate Accessport menus for adjusting idle speeds in A/C ON and A/C OFF conditions.
• Adjust Timing (STI Only): Globally reduce timing on the fly to compensate for poor-quality pump fuel.
• Flat Foot Shifting: Keep the throttle to the floor during gear shifts and maintain boost between gears with customizable RPM settings. (Not available for WRX CVT.)
• Launch Control: Set an RPM threshold for high-performance launches from a standstill. Builds boost and delivers instantaneous horsepower off the line. (Not available for WRX CVT.)
• Launch Mode (Forester XT & WRX CVT Only): Manipulate factory torque limiters to build boost and generate instant horsepower during launches*. Includes driver-controlled activation. (*Requires Accesstuner software to fine-tune the Launch Mode feature.)
