DCCD
Let's talk about more about this clever system .
1. DCCD allows drivers to adjust the handling of their car by varying the lock-up between the front and rear differentials.
Initially introduced in the Subaru Impreza Version 2 STi Type RA, DCCD replaced the standard viscous center differential with a mechanical locking unit and an electromagnetic component.
2. Controls and Functionality:
A thumbwheel lets drivers control the center differential settings, which affects the traction provided by the limited-slip differential.
The purpose is to enhance grip in various conditions (e.g., snow, mud), particularly relevant for rally driving, or just a hooligan.
3. Integration in Subaru Models:
DCCD became standard in global-spec STi Impreza models from 2005 onward and was available earlier in Japanese models.
The GD-series STis featured an Auto setting, allowing automatic adjustments by the computer for optimal performance.
4. Technology Evolution:
Starting in 2018, Subaru transitioned to a fully electronic center differential system, indicating advancements in vehicle technology.
5. Sensor and Communication Systems:
On the later model's The factory DCCD system utilizes multiple sensors (ABS, wheel speed, G-sensors, steering rate, and yaw rate) to assess driving conditions.
From 2008 onward, these sensors are integrated into a Controller Area Network (CAN), complicating the ability to retrofit older vehicles with newer DCCD systems.
What are the benefits of the Driver Controlled Centre Differential (DCCD) in Subaru vehicles?
The Driver Controlled Centre Differential (DCCD) in Subaru vehicles offers several benefits that enhance performance and control in various driving conditions:
1. Improved Traction: DCCD allows drivers to adjust the lock-up between the front and rear differentials, optimizing traction when driving on slippery surfaces such as snow, mud, or gravel.
2. Customizable Handling: With a thumbwheel control, drivers can fine-tune the vehicle’s handling characteristics to suit their preferences or the specific driving environment, enhancing the driving experience.
3. Enhanced Stability: The ability to control the distribution of power helps maintain stability during cornering and challenging maneuvers, reducing the likelihood of oversteer or understeer.
4. Adaptive Performance: In models equipped with an Auto setting, the DCCD can automatically adjust the differential tuning based on real-time driving conditions, allowing for better performance without driver input.
5. Rally Capability: DCCD is particularly beneficial for rally enthusiasts, providing the necessary adjustments to handle the diverse terrains and conditions typical in rally events.
6. Advanced Sensor Integration: The system collects data from various sensors (like ABS, wheel speed, and steering rate), enabling it to respond dynamically to changing conditions, which enhances safety and performance.
7. Vehicle Control: The DCCD provides drivers with more control over their vehicle, allowing them to feel more confident and engaged, particularly in adverse weather or challenging driving scenarios.
These benefits make DCCD a valuable feature in Subaru vehicles, especially for those seeking enhanced performance and control in varying driving conditions.
Retro fitting my favourite saying , Question can we fit it to your car ? Answer Of course we can
DCCD System
1. Parts Required:
DCCD gearbox (recommended)
Propshaft
Gearbox mount
Driveshafts
Rear hubs
Rear differential
Gear linkage
2. Standalone DCCD Controller:
A standalone DCCD controller can be integrated, similar to a standalone engine ECU.
It utilizes inputs from both front and rear ABS sensors to calculate vehicle speed.
3. Customization:
The controller can be programmed based on driving style, weather conditions, and road types, allowing drivers to tailor the system for optimal performance.
4. Advanced Technology:
This retrofit represents a significant upgrade, enabling enhanced traction and handling characteristics tailored to the driver’s preferences and specific conditions.
