AccessPort ECU Upgrade: The Accessport is a mult-featured ECU reprogramming device for your Subaru WRX or STi. The Accessport comes loaded with multiple maps for various setups (i.e. stock, turboback exhaust, etc.). It also allows for custom tuning through Tuners or self-tuning by downloading Cobb's Racer Tuner program. Your Subaru can easily be returned to stock at any time, as the Accessport retains your stock base map. In addition, the Accesport functions as a scan tool, diagnosing and clearing check engine lights (CELs) and other vehicle parameters. The Accessport's color display allows the user to display a variety of parameters including dynamometer testing and real time data.

NOTE: Under Federal EPA regulation, replacement of original catalytic converters is allowed only if the original converter(s) is missing, or the vehicle has more than 50,000 miles or is at least five years old and the need for a replacement has been established and documented, or a local inspection program has determined the existing converter is in need of replacement. Please note that no aftermarket catalytic converters are legal for installation in California on OBD II vehicles (some 1994 & 1995, and all 1996 and later vehicles). There is a chance of seeing a CE Light: Inefficient cat code when running less than two cats, so if seen, contact us for the mechanical fix (sold separately). All performance parts have been designed and are intended for off highway application only. Installation of these parts on a vehicle intended for use on public roads may violate state or federal laws and regulations including those relating to emissions requirements and motor vehicle safety standards.

**Note: Xcceleration.com highly recommends you install a boost gauge, exhaust gas temperature (EGT) gauge, air/fuel gauge and a knock sensor to monitor your car and ensure safe, reliable performance. Gauges are sold separately - Please appreciate, we just think that if you spent ~$25k+ on a high performance car like the WRX and even more $ to make it perform even better, you should seriously consider spending a few hundred $ additional to monitor some key parameters!
