Stage 1 maps deliver immediate gains of +35 HP and +40 lb-ft of torque on completely stock vehicles using 91-93 octane fuel.

The device features intelligent real-time ECU remapping that optimizes ignition timing, boost control, fuel delivery, and cam timing across the entire RPM range. Unlike generic tuning chips, the Accessport provides vehicle-specific calibrations tested on thousands of Subarus, ensuring safe, reliable performance gains without compromising engine longevity.
🎯 Advanced Features Beyond Basic Tuning
Performance Monitoring Dashboard
The full-color, high-resolution display transforms into a customizable gauge cluster, monitoring up to six parameters simultaneously. Track boost pressure, air/fuel ratios, coolant temperature, knock detection, oil temperature, and dozens of other critical engine parameters in real-time. This diagnostic capability helps identify issues before they become problems, potentially saving thousands in repair costs.
Launch Control & Flat-Foot Shifting
Activate factory-style launch control for consistent starts at the track, with adjustable RPM limits for different tire and surface conditions. The flat-foot shifting feature maintains boost pressure during gear changes, eliminating turbo lag and delivering seamless acceleration that shaves seconds off quarter-mile times.
Data Logging & Performance Testing
Record detailed data logs for professional tuning analysis or track your performance improvements with built-in 0-60 mph and quarter-mile testing modes. Export logs directly to your computer for analysis in Accesstuner software or share with professional tuners for custom map development.
🔧 Installation & Daily Use Benefits
Installation takes less than 10 minutes with no tools required - simply plug into your OBD-II port located under the driver's dashboard. The Accessport automatically backs up your factory ECU settings, allowing complete reversibility for dealer visits or vehicle sales. The compact design fits perfectly in your cupholder or glovebox, ready for map changes based on fuel quality or driving conditions.
Switch between performance and economy modes instantly. Run aggressive maps for weekend canyon drives or track days, then switch to economy-focused calibrations for daily commuting, potentially improving fuel economy by 2-3 MPG during highway cruising.
💻 Professional Tuning Platform
For enthusiasts seeking maximum performance, the Accessport serves as the foundation for professional custom tuning. Compatible with Accesstuner Pro software, professional tuners can create bespoke calibrations for heavily modified engines, including those with upgraded turbochargers, fuel systems, and internal modifications. The device supports unlimited custom map storage, allowing you to save tunes for different fuel types, elevation changes, or seasonal adjustments.
