Aftermarket standalone Automatic DCCD controller for JDM and USDM 6 speed transmissions as well as older 5 speed DCCD transmissions.
Did you swap the transmission in your car and need to control the DCCD?
This product is specifically designed for swapped cars, and includes everything required for automatic and manual DCCD operation, including an advanced hardware and software design of the custom control module in a water resistant enclosure, with a nice adjustment knob for setting the locking force, this system is infinitely adjustable between fully locked and unlocked levels.
Each control module is fully bench tested prior to shipment.

- Microprocessor Controlled
- 2 axis high resolution g-sensor
- custom firmware with driver adaptive capability
- several internal modes based on driver throttle behavior and g- sensor behavior that switches on the fly automatically
- DCCD calculations are using advanced formulas instead of unintelligent static mapping or lookup tables
- This controller also features direct manual control of the center diff
- Unique and exclusive Left Foot Braking option
- Can be optioned with both the OEM STi thumbwheel control and OEM STi Auto / Man switch so that you can maintain the factory look
- Can also be optioned with an interface to the STi cluster display to show "real time" power output to the DCCD
The hardware and firmware were designed to work together to be as "driver transparent" as possible. My philosophy is that the less you need to adjust or monitor while driving the more you can concentrate on the road / race.
During development I considered various options including a knob to select "modes" and / or different formula as well as an LCD to monitor the DCCD output, but when it came down to it they added greater cost to the final product and had little to offer in terms of real functionality. The control knob for the system is used to scale the DCCD "aggressiveness". Fully CCW turns the unit essentially "off" which will heavily bias the rear wheels, full CW gives it full "aggressiveness" maximizing traction and thusly increasing under-steer. In this setting the system will attempt to give you maximum traction at all times by trying to maximize the amount of DCCD lock at all times. The system is infinitely variable between these two extremes. Start at lower settings (over-steer) and increase the knob setting until you find the car handles the way you would like it to in the corners. You can alter the setting at any time and on the fly as conditions change.
This DCCD controller constantly and frequently monitors the attached sensors, updating the DCCD output based on how the car is behaving in reaction to driver inputs. It features several firmware modes that it switches between on the fly. Without going into a detailed explanation of the firmware formulas, the system automatically switches between formula appropriate for "parking lot / highway cruise", aggressive cornering", "aggressive straight line", and "stuck in snow/mud" based on what information it receives from the sensors.
It monitors the output level as well as the speed at which the various sensors change. For example it can differentiate between slow gradual throttle application vs. rapid throttle acceleration and respond accordingly. The internal firmware formulas try to mimic the behavior of the OEM STi DCCD auto mode.
When the led illuminated switch is pressed, this controller can manually control the output to the dccd from the control knob or STi thumbwheel.
The controller features both auto and direct manual control of the dccd. It can also be interfaced to the STi dccd display in some STi clusters to display the output level of the dccd signal. The display will rise as power levels increase.
