Tein EDFC units are manufactured to allow most Tein coilovers with dampening adjustability to be tweaked on the fly! You can change the dampening settings of your coilovers from the comfort of your cockpit with any of the Tein EDFC kits offered. Below is a quick run through about the difference between each model. If you have any questions about what components you will need for your application, we are a phone call or an email away from helping you out!

EDFC II Controller:
The original TEIN EDFC, which has been popular for the past decade, is reborn as "TEIN EDFC II" with a new appearance using white LED and at a new affordable price.
"EDFC II" brings the convenience of in-car damping force adjustment system to the hands of more people than ever.
Easily Controlled from the Inside!
To control the damping force, the driver usually needs to get out of the car, raise the hood and/or take off rear interior parts such as the speaker board or rear seat. With EDFC II, all the driver has to do is simply push the buttons on the controller to adjust damping force without even setting a foot outside the vehicle.
Easy-to-Recall Memory Contents!
With just a touch of a button, damping force is adjusted to the preset setting instantly. Up to 3 presets are available to store the preferred settings.
Simple Operation at Your Fingertip!
It is so easy to operate. All the basic operations can be done with just a single touch of either damping force adjustment buttons for front and rear (+/-) or 3 preset buttons.
Despite the use of high-performance & high-precision stepping motors, EDFC II is very attractively priced.
Functions / Features
High-Performance Stepping Motor for Damping Force Control
High-performance stepping motor is attached to the shock absorber, in place of the damping force adjustment knob. Damping force is adjusted by controlling the motor remotely from the controller unit installed inside the vehicle.
2 Damping Force Adjustment Modes (16 levels / 32 levels)
Damping force adjustment levels can be set in 2 different types; 16-level or 32-level. Most TEIN damping force adjustable dampers come with 16-level adjustment. Use of EDFC II adds 32-level adjustment capabilities within the same range for finer adjustments.
Up to 3 damping force settings can be stored into a memory. With this feature, preferred setting can be recalled instantly with only a touch of a button, according to various driving conditions; from streets, highways to winding roads.
The system remembers the damping force setting when the ignition key is turned off and automatically returns to the same setting when the key is turned back on. (Main power switch for the controller unit should stay on, for this function to work.)
Volume of button sound can be set to level 0 (mute) and between level 1 (low) & 3 (high).
Display Dimmer Function
Brightness of the display is dimmed automatically at night in conjunction with the illumination power supply. Brightness at dimmed state can be set to 3 levels.
Self-Diagnosis & Alert
When the system detects any abnormality (wire breakage, short circuit etc), an alarm sound is emitted, all 3 memory buttons flash in red and an error message is displayed on the screen.
Operation of all buttons can be locked to prevent operation mistakes.
*This product does not adjust vehicle ride height.
EDFC ACTIVE makes it possible to adjust damping force with ease from the driver's seat, by controlling stepping motors installed on each shock absorbed Built-In G-Sensor allows G-actuated automatic adjustment of damping force while driving. Additional automatic speed-sensitive damping force adjustment feature is available with the use of optional "GPS kit" (sold separately).
More Aggressive Damping Force Control
To control damping force more actively according to driving conditions, 2 automatic adjustment modes are available; "G-actuated automatic adjustment mode" and "speed-sensitive automatic adjustment mode (optional GPS kit is required)". Damping force adjustment levels can be set in 3 different types; 16-level, 32-level or 64-level.
Motor driver units, located at front and back of the car, and controller unit are connected wirelessly, to reduce troublesome wiring works. Controller unit has all the sensing functions, with built-in optical sensor to detect brightness in its surroundings and connectivity with optional GPS kit to detect vehicle speed. The power supply cable is the only wiring required between the controller and the vehicle, making it possible and easier to install onto wider varieties of vehicle models. Well-considered size and design enable controller unit to be installed to most desirable position easily without any bulky wiring.
Better Visibility & User-Friendliness
Larger display is used for improved visibility and one-dial operation allows for easier handling.
