EDFC ACTIVE PRO

*Can only be used with TEIN shock absorbers

Automatic damping force adjustment, based on the vehicle's speed.
For example on urban streets, you can automatically have soft damping force at low speed for a cushioned ride, and stiff damping force for stable handling while driving fast.

Likewise on circuits, you can enjoy the right handling quality at any speed, for instance automatically adding a pinch of oversteer at sharp turns, and slight understeer at moderate turns.

Automatic damping force adjustment, based on acceleration and deceleration G-force (longitudinal G-force).

On the street you can unite ride comfort with handling stability, setting a soft damping force at constant speed to smoothly absorb the road's unevenness, and a stiff one at acceleration/deceleration to constrain vehicle movement.

Furthermore on circuits, setups allow for increased stability at braking, as well as under- and oversteer control by varying front-rear damping force balance depending on the accel/deceleration amount.

Automatic damping force adjustment, based on lateral G-force such as during cornering.
Want to combine a comfortable ride with smooth cornering? Just set damping force to be soft while driving straight to compensate surface flaws, and stiff only at turns, suppressing the vehicle's roll velocity.
You can pre-set the damping force to the amounts of the lateral G-forces, and also customize the balance between front and rear damping.

With just one dial, front and rear damping force levels can be adjusted as desired.
The preset memory function stores up to 10 setups. You can instantly switch to your preferred damping force levels for any situation.

EDFC ACTIVE PRO features wireless control, for easy installation and wiring.
The controller wirelessly communicates with the motor driver units that command EDFC motors. No more need to pierce cables through trunk or engine firewalls and snaking them about the vehicle.

The latest wireless technology enables instant and reliable adjustment motor response upon operating the controller unit. Of course, the network signal is reliable. Also interference is no worry, since each motor driver unit has one in 16.77 million unique IDs.
Motor driver units are made extremely dustproof and waterproof, so that they can be installed outside the vehicle's passenger compartment, such as in the engine bay.

You can choose the degree of fine-tuning for damping force adjustment: 16, 32 or 64 levels. TEIN shock absorbers usually offer 16-level adjustment, and EDFC Active Pro offers an additional scope of precision. This is especially effective in automatic adjustment modes.

You can adjust the color of the display, button and dial illumination. In addition to 4 default colors (white, green, amber and blue), the EDFC5 offers a spectrum of 262,000 colors to customize your controller unit.

EDFC Active Pro is able to control up to 8 motors for individual damping force adjustment, with just the one controller unit. This requires additional motor driver units.
The controller unit displays compression and rebound damping force levels simultaneously, and it can adjust each separately. All functions of EDFC Active Pro are available, including automatic adjustment modes.

The brightness of the screen, buttons and dial adjusts automatically to the surroundings. Detecting the ambient light intensity with a sensor, EDFC5 does not need to connect to the vehicle's illumination signal.
You can set the basic light level manually (3 levels), and brightness auto-adjustment fine-tunes it for optimal visibility. The auto-adjustment function can be switched on/off.

The EDFC Active Pro controller features a handy speedometer display option. It includes a peak speed memory function, and allows you to see your speed in km/h or mph as you prefer.

With just a simple external trigger, such as a touch or action, preset damper settings can be activated. This requires connecting the controller to an existing signal or separately purchased switch (2 ports available).
For example: connect to parking brake signal for instant damping force adjustment when you're drifting

Save the suitable setup for that particular situation, and you can activate it instantly with a single touch.

A variety of features, such as a G-sensor and wireless communication, are combined into one compact unit. The wide display (22 x 60 mm) offers good visibility.

A wiring duct at the back lets you neatly route the cables, offering more flexibility to install the EDFC controller where you want.

Other than its default Damping Force Level Display, the EDFC screen switches to G-Force Display (numerical as well as graphic) and Speedometer Display. In addition, the optional GPS kit enables a further array of display modes: Altitude, Longitude, Latitude, Tripmeter and Clock.

Both acceleration/deceleration G-force and cornering G-force show in numbers as well as bar graphics.
With peak G-force memory.
G-Force bar scale can be switched: 0.3 or 1.0 G.

A motor reset function is built in for the upkeep of correct damping force levels. At every start-up, the adjustment motors first rotate to maximum stiffness (level 0), before resuming their previous positions. Especially for users who mind the sound, the option is included to change the reset frequency from each start-up to once in every 10 start-ups or never.

Please note:

• We recommend to perform a reset regularly, to maintain correct damping force adjustment levels.
• The start-up reset is performed each time the controller unit is manually turned on.

You can specify a minimum vehicle speed, at which to start accel/deceleration- and cornering-reactive automatic damping force adjustment. This is convenient if you don't need it when you drive slowly, or if you mind the sound of the EDFC motors. The start speed can be set between 0 and 50 km/h (or 0 to 50 mph); under that speed g-force-reactive auto-adjustment will be off.

For easy operation, EDFC Active Pro features a one-dial system. Intuitive and simple, the dial is turned to scroll, and pushed to confirm. The 2 buttons above it switch the mode and display.

Since the G-sensor contained in the controller unit works along 3 axes, the controller can be installed at just about any angle.

The controller's display settings offer an alternative view angle, to ensure visibility.

The volume of the button/dial push sound can be set between levels 0 (mute) and 3. This also applies to the volume of system signals during auto-adjustment.

EDFC Active Pro offers a lock function to disable the buttons and dial, for instance during driving. This prevents accidental operations.

The system boasts a self-diagnosis feature that can determine the performance of motor driver units, wireless communication, etc. Any problem will appear on the screen, such as a disconnected or short-circuited motor driver unit, or trouble with the wireless signal.

The housing of the motor driver units is made of highly heat resistant material.

EDFC Active Pro requires a Controller Kit and an EDFC Motor Kit.

A GPS Kit is required if the speed pulse cannot be taken from the vehicle, or if you want all functions to work.

A Strut Kit or a Motor Extension Kit may be needed depending on the vehicle model.

1. Setup Programming: How to input your preferred setup into a memory space.
2. Relative: Specify the damping force adjustment of each damper, compared to your standard levels.
   E.g. -12, 20 (for +20), etc.
3. Absolute: Simply input the damping force level for each damper, e.g. 32, 48, etc.

Feel free to download our template to jot down your personal damping force presets, for handy reference. It's available in Excel as well as PDF format, via the buttons below.

Your EDFC Active controller unit can be upgraded to the EDFC Active Pro version, by updating its software. Purchasing a signal converter will add functions that use the vehicle’s speed signal, such as the speed-reactive adjustment mode and instant damping force setup activation by external signals, so that you have complete EDFC Active Pro functionality.

To upgrade, please contact your nearest TEIN dealer. You can also use the Contact Form to send us your request or questions.
