Transform Your Subaru's Performance with Professional ECU Tuning

Transform your Subaru's performance with the Cobb Accessport V3 (AP3-SUB-003), the industry's most trusted handheld ECU tuning device. This powerful tuner unlocks your turbocharged Subaru's hidden potential through professional-grade engine management, delivering instant power gains, improved throttle response, and enhanced drivability for your WRX STI, Forester XT, Legacy GT, or Outback XT.

✓ Compatible Vehicles

  • 2008-2014 Subaru WRX (All trim levels)
  • 2008-2014 Subaru STI (Including Special Editions)
  • 2007-2013 Forester XT (Turbocharged models only)
  • 2007-2012 Legacy GT (2.5GT and Spec.B)
  • 2007-2009 Outback XT (All turbocharged variants)

⚡ Instant Performance Gains with Pre-Loaded Maps

Right out of the box, the Accessport V3 includes Cobb's extensively tested Stage 1 and Stage 2 off-the-shelf (OTS) maps, engineered specifically for your Subaru's ECU. Stage 1 maps deliver immediate gains of +35 HP and +40 lb-ft of torque on completely stock vehicles using 91-93 octane fuel. For modified vehicles with upgraded intakes and exhausts, Stage 2 maps can unlock +65 HP and +70 lb-ft of torque, transforming your daily driver into a genuine performance machine.

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.

Went from open source to cobb

Great product and my tuner is great we have 2 STI in the house so this is a necessity. Great to be able to see what is going on real time with the vehicle and makes diagnostic of issues a breeze with recorded data.

Always a great product.

It’s been a long time since I had to get a new AP. Easy to set up and works exactly as I wanted/remembered. I did need to add the stage 2 map but my fault for not checking. Great support also when needed. For sure recommend this product.

Worth the price

The monitors are extremely useful for understanding how your car is behaving under certain conditions. I loaded the Stage 1 tune, and it completely changes the feel of the car. With 93 octane fuel, I use the 91 octane tune to be safe. The shipping process and customer service were both great.
