Unlike other tuning options, the AccessPORT is truly unique in its capabilities that go far beyond typical chipping or reflashing solutions. This is where the AccessPORT clearly stands out from the competition:
Simple Installation - Just about anyone with even the most basic of automotive knowledge can quickly and easily install an AccessPORT. No computers, wire cutting/splicing or tools of any kind are required.
Base Maps - COBB Tuning provides several preloaded maps for common power modifications. Each base map is dyno developed and rigorously tested in multiple COBB Tuning facilities across the country These tests cover the spectrum of altitude, temperature, humidity, octane and fuel quality variables to ensure proper calibration and performance wherever the car is driven.
Change Maps - Since all base maps and custom tune maps are stored in the AccessPORT, you can change maps any time you want. Switch to a race gas map for that extra performance at the track. Go to the Fuel Economy map for those long boring drives. Load the Valet map to keep revs below 3,200 when you drop your car off with the parking attendant. The Anti-Theft map does not allow the car to start, keeping it safe in suspect areas or during extended parking.
Performance - Turn on your own portable performance evaluation suite! Measure 0-60mph time, 60 foot and 1/4 mile ETs and Trap Speed. Switch to Dynamometer simulation and calculate your vehicles horsepower and torque.
Live Data - Monitor OEM sensor data on-the-fly. Use the AccessPORT as an additional gauge to monitor a huge number of signals, like: RPM, Intake Air Temp, Boost Pressure, Baro Pressure, Abs Pressure, MAF, Ign Advance, Injector Pulse Width and many more!
Datalogging - Onboard datalogging allows multiple channels of data to be recorded simultaneously for later review. This allows for analysis of current engine performance. Datalogs can be sent to professional tuners to provide additional power gains remotely through email!
Trouble Codes - The AccessPORT allows you to read engine codes to troubleshoot issues and potentially save you from an expensive trip to the dealership. Once the issue is resolved, clear the codes and turn off the check engine light.
Uninstall - In the event the car must be returned to the stock configuration, the AccessPORT can be completely removed and the ECU restored to its factory condition. Perfect for trips to the dealership.

Subaru WRX, STi, Legacy, Others
The ultimate personal tuning solution for your Subaru. Reprogram your vehicle's computer (ECU) by selecting one of the pre-installed performance "maps" that automatically optimize settings such as the air/fuel ratio, ignition timing, boost and more for performance results you can instantly feel!
However, the AccessPORT is so much MORE than just a REFLASH DEVICE. It allows you to monitor your Fuel Economy (average and real time), perform performance tests in order to estimate your 0-60mph and 1/4 mile time, read and decipher ECU trouble codes (CELs), and monitor live data via the OEM vehicle sensors which eliminates the need for costly aftermarket gauges.
WRX: This is where to start your quest for additional power and response from the WRX. Included in the Stage 1 Kit is the highly regarded AccessPORT which is used to reprogram the factory engine computer, unlocking an additional 33 HP (power) and 43 lb-ft (torque) from a WRX and increases boost to approximately 14.7psi.
STi: This is where to start your quest for additional power and response from the STI. Included in the Stage 1 kit is the highly regarded AccessPORT which is used to reprogram the factory engine computer, unlocking an additional 25 HP (power) and 40 lb-ft (torque) from a STI and increases boost from 14.5psi to approximately 16psi.
