Tein EDFC5 Active Pro Controller Kit - EDK04-R6655

The Tein EDFC5 Active Pro Controller Kit (EDK04-R6655) is Tein's most advanced electronic damping force controller, engineered for drivers who want intelligent, on-the-fly suspension adjustment without ever reaching for a wrench. Compatible exclusively with select Tein shock absorbers, this universal controller kit brings together AI-driven learning, jerk-reactive technology, and multi-mode automatic adjustment to deliver a suspension experience that adapts to your driving style and road conditions in real time.

Key Features & Benefits

• Jerk-Reactive Adjustment (Patent Pending No. 2022-188410): Developed in industry-academia collaboration with Prof. Dai Watanabe of the Shibaura Institute of Technology, this technology calculates jerk rate from changes in G-force to predict how the vehicle is about to move. Damping force is adjusted at the very moment cornering, acceleration, or braking begins — striking a balance between sharp handling and a comfortable ride that traditional G-actuated systems cannot match.
• AI Learning Function: The system studies your driving behavior over time and refines its automatic adjustment patterns for highways, city streets, winding roads, and track environments — eliminating the sense of discomfort that can come with abrupt damping changes.
• Longitudinal & Lateral G-Actuated Adjustment: Separate control logic for acceleration/deceleration and cornering G-forces lets you run a soft damping force at steady cruise for road-noise compliance, then automatically stiffen up under braking or in corners to suppress body roll and control under/oversteer balance.
• Speed-Sensitive Adjustment: Damping force can be mapped to vehicle speed — soft at low urban speeds for comfort, progressively firmer at highway speeds for stability — automatically, without driver input.
• Quieter Motor Operation: EDFC5 employs a new motor-control approach to reduce operating sound, maintaining the quietness expected of OEM-level components.
• VA LCD Screen with 262K-Color Display: The controller uses a VA (Vertical Alignment) panel instead of the HTN panel found in previous EDFC generations, delivering a noticeably more vivid, easier-to-read display with automatic brightness adjustment.
• Finer 96-Level Adjustment Mode: Selectable precision levels of 16, 32, 64, or 96 steps allow fine-grained tuning suited to both street and motorsport applications.
• Manual Mode & Combined Control Mode: When you want direct control, manual mode lets you adjust front and rear damping force independently with a single dial. Combined control mode links front and rear for quick global adjustments.
• Preset Memory Function: Save your preferred damping setups and recall them instantly — useful when switching between street and track configurations.
• Wireless Control: Adjust settings without fumbling with wired connections.
• Various Color Options: Controller display is available in multiple color themes to suit cockpit aesthetics.

Fitment

The Tein EDFC5 Active Pro Controller Kit is a universal kit designed to work exclusively with compatible Tein shock absorbers. It is not compatible with non-Tein dampers. Confirmed compatible Tein shock absorber lines include:

• EnduraPro HC PLUS
• EnduraPro PLUS (SP KIT, Street Use)
• RX1
• 4x4 DAMPER
• SPORT
• STREET ADVANCE Z4
• FLEX A
• FLEX Z
• STREET ADVANCE Z
• MONO RACING

Important: This unit does NOT work with the older EDFC Active or EDFC Active Pro controller units — it is not a drop-in replacement motor driver for those systems. A compatible EDFC Motor Kit is not included and must be purchased separately. A GPS Kit is required if a speed pulse signal cannot be sourced from your vehicle, or if you wish to use all available automatic functions. Depending on your specific vehicle model, a Strut Kit or Motor Extension Kit may also be needed. Use Tein's compatibility search tool to confirm fitment for your exact vehicle before ordering.

Frequently Asked Questions

Is the EDFC Motor Kit included with the EDK04-R6655?

No. The EDFC Motor Kit is not included and must be purchased separately. This listing covers the EDFC5 Active Pro Controller Kit only. You will need the appropriate motor kit to complete your installation.

Can I use the EDFC5 with my older EDFC Active or EDFC Active Pro controller?

No. The EDFC5 motor driver unit is not compatible with the older EDFC Active or EDFC Active Pro controller units. Do not attempt to mix components from these generations.

Do I need a GPS Kit?

A GPS Kit is required if your vehicle cannot supply a speed pulse signal to the EDFC5, or if you want all automatic functions — including speed-sensitive adjustment — to operate correctly. If you are unsure whether your car provides a usable speed pulse, contact our team before ordering.

Will the EDFC5 work with non-Tein coilovers or shocks?

No. The EDFC5 is designed exclusively for use with Tein shock absorbers. It cannot control damping force on dampers from other manufacturers.
