The Tactrix Openport 2.0, a powerful tuning tool, interfaces with most OBDII-compliant vehicles via a standard J2534 interface. When paired with EcuFlash software, it enables reflashing numerous Subaru and Mitsubishi vehicles, with expanding support for other makes. While the Openport 2.0 connects through the OBDII port, certain older Subaru models require a separate reflash adapter for successful ECU reflashing. This article focuses on identifying the Subaru Reflash Connector and when an adapter is necessary.
Understanding the Need for a Subaru Reflash Connector
The Openport 2.0 typically connects directly to the OBDII port for data logging and reflashing. However, some early Subaru models, specifically the 2001-2005 WRX (excluding STi), utilize a different connector for reflashing the ECU. This necessitates a specific reflash adapter to bridge the connection between the Openport 2.0 and the vehicle’s ECU. Non-USDM STis from this era may also require the WRX adapter.
Identifying Subaru Models Requiring a Reflash Adapter
As mentioned, the 2001-2005 WRX requires a reflash adapter. It’s important to note that the STi models from these years do not typically require the adapter. Other Subaru models, including the Forester, Baja, Legacy, and naturally aspirated Impreza, connect directly to the OBDII port for reflashing without needing an adapter. For Mitsubishi vehicles, the adapter is generally necessary for most pre-CAN models, including the Evolution 5-9.
Locating the Subaru Reflash Connector
The Subaru reflash connector, when required, is usually located under the dashboard on the driver’s side. It is a green, rectangular connector with multiple pins. Consult your vehicle’s service manual for the precise location of the reflash connector for your specific model year.
Using the Reflash Adapter
If your Subaru requires a reflash adapter, connect it to the Openport 2.0 before plugging it into the vehicle’s reflash connector. Ensure a secure connection to both the adapter and the vehicle’s connector. Once connected, you can proceed with the reflashing process using the EcuFlash software.
Conclusion: Ensuring Proper Reflashing Procedures
Understanding the need for and location of the Subaru reflash connector is crucial for successful ECU reflashing. While most Subaru models utilize the standard OBDII port with the Openport 2.0, certain older WRX models require a specific adapter. Always refer to your vehicle’s service manual and the Tactrix Openport 2.0 documentation for accurate information and instructions to ensure a safe and effective reflashing process.
