Adjust Damping Force from the Driver's Seat!

MSRP JPY 34,500 excl. Tax

Revamping the long-popular pioneer electronic damping force control system EDFC, the EDFC II features functional touch-ups, white LED light and an affordable price. EDFC II brings the convenience of damping force adjustment from the driver's seat to a wider audience. Please note that this product does not adjust vehicle ride height.


Control from the Driver's Seat

To adjust damping force, you do not need to get out of your car, remove interior parts or even open your hood/trunk. With EDFC II you can stay in your seat and simply press some buttons.

One-Touch Setup Activation

With one push of a memory button, damping force instantly adjusts to a previously stored setup. Three presets are available.

Super Simple Operation

All basic operations can be performed with just one button: (+) or (-) for front or rear to adjust damping force, or a preset button.

Affordable Price

Priced from JPY 29,500 (excl. tax) per car, even while boasting high-performance and high-precision stepper motors, EDFC II is an exceptional bargain.

Functions / Features

High-Performance Stepper Motors to Adjust Damping Force

Each shock absorber's adjustment dial is replaced with a high-performance stepper motor ("EDFC motor" or "adjustment motor"), and a controller unit is installed in the cockpit for remote damping force adjusting.

System Layout

16- and 32-Level Adjustment Modes

The EDFC II features two modes of precision for your damping force setup: either 16 or 32 damping force adjustment levels. Where the standard for damping force adjustable TEIN dampers is 16 levels, the 32-level mode enables finer adjustment.

One-Touch Setup Activation

You can store up to 3 preferred damping force setups in memory. This memory preset function allows you to instantly switch to damping force levels that you have set in advance for certain driving conditions, such as city, highway or winding roads.

Resume Feature

This function allows you to start driving with the same damping force setup as when the last drive stopped. (This requires the main power of the controller unit to stay on)

Sound Volume Adjustment

The volume of the button push sound can be set between levels 0 (mute) and 3 (loud).

Display Dimmer Function

The display dims at night, in conjunction with the vehicle's illumination signal. The dimmed display offers 3 levels of brightness to choose from.

Self-Diagnosis and Alert

When the system detects an abnormality (disrupted connection, short-circuiting, etc.), an alarm sounds while the 3 memory buttons flash red and the screen shows what is wrong.

Button Lock

The buttons can be disabled, to prevent accidental operations.
