Subaru didn't give us the VB STi, but that doesn't mean we can't make our own.
iDCCD harnesses the power of your Vehicle's CAN bus Network for a simple install, with serious capabilities.
An STI 6-speed transmission transforms the driving experience of the 2022+ WRX. But without intelligent DCCD control, one of the transmission's most advanced features remains untapped.
The iWire iDCCD brings the sophistication of Subaru's legendary Driver Controlled Center Differential to the modern WRX with seamless integration, refined control, and a level of capability that simply wasn't available from the factory.
Designed specifically for your 2022+ WRX with an STi transmission swap, iDCCD works quietly in the background, continuously optimizing center differential lock to help deliver confidence, traction, and balance in every driving situation.
Engineered for Your VB WRX
Great technology feels invisible.
By communicating directly with the vehicle network, iDCCD monitors real-time vehicle data and makes hundreds of intelligent adjustments as conditions change. Whether navigating a rain-soaked freeway, carving through mountain roads, or chasing lap times, the system responds instantly to help maximize grip and stability.
The result is a driving experience that feels natural, predictable, and remarkably refined.
Precision Without Compromise
Every aspect of iDCCD was designed with simplicity and performance in mind.
- Plug-and-play installation with vehicle-specific harness and bracketry
- Intelligent automatic control modes
- User adjustment within the control modes
- OEM STi control panel integration
- Smartphone app configuration, customization, and display
- Seamless CAN bus integration
- Firmware updates for future enhancements
- Designed, developed, and supported by iWire in the USA
Unlock the Full Potential of Your Drivetrain
An STI transmission is more than stronger gears and a better driving feel. At its core is one of Subaru's most capable performance technologies.
iDCCD unlocks the full capability of the center differential, actively managing torque distribution to improve traction, cornering balance, and driver confidence across changing road and weather conditions.
The difference is not just something you see on paper. It is something you feel every time you drive.
Built for What's Next
The best technology improves over time.
Because iDCCD communicates directly with the vehicle's CAN bus network, it serves as a platform for future expansion. New features, functionality, and performance enhancements can be delivered through firmware updates, ensuring your system continues to evolve alongside your vehicle.
This is more than a DCCD controller.
It is the control center for the next generation of STI-swapped WRXs.
