The newest marvel from Tein isn’t a coilover system but rather an accessory to their existing coilovers. It is a G-Force and Speed sensing EDFC that sets the dampening force according to these two forces; Tein calls it the EDFC Active. The Brand New EDFC Active still allows the driver to adjust the dampening force from within their own cockpit, but now one is also able to configure the unit and correlate dampening force with G-forces!

The EDFC active has built in G-sensors that allow automatic adjustments to the dampening force while cruising on the highway or in a spirited outdoor race. It has 2 aggressive automatic adjustment modes; The “G-Force actuated adjustment mode” and the “Speed-sensitive automatic adjustment mode” (The latter mode would require their optional gps kit). Both of these modes can then be further adjusted in a 16-level, 32-level, or even 64-level way. So there is lots of personalization allowed in the system.

A Motor Kit and Strut Kit are needed to physically move the dampening settings on the Tein Coilovers. (Sold Separately)

** In order to use the “Speed-Sensing automatic adjustment mode” the optional GPS Kit is needed and sold separately.

FEATURES:

EDFC ACTIVE Offers Front and Rear  independent control	EDFC Active PRO Offers Front+Rear AND Left+Right  independent control

Longitudinal Control - braking and accelerating - The Tein EDFC Active PRO Controller takes suspension control to the next level offering independent front and rear control and adds ACTIVE control based on the built-in G-sensor, and even speed-sensitive control with the optional GPS unit! You can program it to be soft when driving straight and then automatically go firmer when you get on the brakes and then full firm if you brake hard. It can be programmed to automatically adjust the front and/or rear to match the intensity of your stopping and starting.

Lateral Control - left and right - Unique to the Tein EDTC Active PRO, you can fine tune your suspension to independently set left and right damping force, greatly improving overall handling when making turns and cornering. And the ACTIVE component means the you can set it so the harder the corner (higher G-forces sensed by the controller) the stiffer the suspension on the counter-side.

Optional GPS Unit

You also can add the optional GPS Unit which then allows you to additionally program for vehicle speed as well a G-forces. For example, on streets, damping force can be set to a softer level while driving slower for softer ride without any bumpy feel and set to harder level when driving faster for better stability and handling. On a road course, damping force can be controlled according to speed range to change handling performance, such as reducing understeer a bit at low speed corners and reducing oversteer a little at high speed corners. This truly gives you full control over your suspension so you can program it for higher speed turns as well as lower speed turns, as well as factoring in accelerating and braking forces.

Signal Converter for Vehicle Speed Input

In addition to the vehicle speed calculated by the use of optional GPS kit, EDFC ACTIVE PRO can adjust damping force according to the vehicle speed signal data obtained via external input port. This enables uninterrupted speed-sensitive adjustment even when/where GPS signal is not available. It is required to know the type of speed pulse because it varies quite a bit by vehicle models, but EDFC ACTIVE PRO can be programmed easily without such details. To set up, nothing other than the controller is needed. *Acquisition of speed signal might not be possible with some vehicle models. In such case, the speed-sensitive adjustment is only available with optional GPS kit used.

3 Levels of Adjustment Precision

Damping force adjustment levels can be set in 3 different levels of precision; 16-level course adjust, 32-level or 64-level fine adjust within the same range allowing for smoother transition with active / automatic programming modes.

Wireless Installation & Control

Tein EDFC ACTIVE features a wireless control system for easy installation and wiring. The control unit is connected wirelessly to the motor driver units which control the motors, eliminating the need for troublesome wiring such as putting cables through bulkheads and/or placing/anchoring cables inside the car. With the latest wireless communication technology, 16.77 million ID patterns are available for motor units and hence there is no chance of confusion with other units. Motor driver units are built to provide tougher protection against dust and water, to make it possible to install outside the vehicle.

Tein EDFC ACTIVE Controller

The main controller features a large 60x22mm LED display screen which is color programmable and displays various information depending on the selected display mode. Simple is key. All the basic operations can be done via the single knob and 2 option buttons. This unit houses the triaxial G-sensor (meaning it can be mounted at any angle) and wireless functions to control the motors. It even houses an optical sensor to support the auto-dimming function so it is not as bright at night. The only hookup needed for the controller is power and ground, and the optional GPS Unit if you get that.

The controller features a host of features:
* Triaxial Acceleration Sensor - The controller has a built-in triaxial G-sensor, which offers the ability to install the controller unit at any desired angle & direction.
* Automatic Display Dimmer Function - Brightness of the display can be automatically adjusted according to the brightness of its surroundings detected by an optical sensor. This eliminates the need for connecting cables to your vehicle's illumination power supply. The auto-dimming function can be turned off. 
* One-Dial Operation - A simple one-dial operation is adopted with emphasis on convenient handling. This user-intuitive interface requires only a few basic operations to remember; turn the dial to select/adjust, push the dial to confirm and push 2 buttons above the dial to switch between the different functions. 
* Switchable Display View Angle - Viewing angle of display can be adjusted in 2 different angles to offer better visibility even when the controller unit is installed at an angle. 
* Buzzer Volume Adjustment - Volume of "button sound/buzzer" and "auto-adjustment buzzer" can be set separately between level 0 (mute), 1 (low) and 3 (high). 
* Self-Diagnostic Function - The self-diagnostic function checks the status of driver unit and/or wireless communication. If it detects any errors in driver unit (disconnection / short circuit) and/or problem in wireless connection, the result will be shown on display. 
* Programmable Display Color - In addition to 4 default colors (white, green, amber & blue), fine-tunable custom colors are available.

* Various Display Functions - In addition to the usual damping force display (with G-force bar graph on/off), G-force (numerical values & bar graph) can be shown. With the optional GPS kit, vehicle speed, altitude, longitude, latitude, trip meter and clock can be displayed.
