We include a USB cable with each OpenPort, which is all the hardware you'll need unless you have one of the few vehicles that require a separate reflash adapter. For Subaru you'll only need a reflash adapter for the 2001 through 2005 WRX, but not STi, unless you're working on an early non USDM STi in which case you made need one of our WRX adapters. No other Subaru vehicles require reflash adapters including Forester, Baja, Legacy, or naturally aspirated Impreza models. For Mitsubishi, you'll need the adapter for most pre CAN vehicles which include the 5-9 Evo. Choose the adapter you need from the 'Reflash Adapters' drop down list on the right side of this page.
