EDFC ACTIVE PRO is a high-spec version of EDFC ACTIVE, which enables automatic adjustment of damping force according to the changes in longitudinal G-force and vehicle speed, and comes with new and upgraded functions.
Newly-added features, such as individual adjustment of 4 shock absorbers, lateral (cornering) G-actuated automatic adjustment, vehicle speed pulse input and 2 additional input ports to communicate with drivers, are sure to bring out the full potential of each shock absorber as well as the vehicle itself. Please enjoy another dimension of shock absorber performance that EDFC ACTIVE PRO brings.
* This product does not adjust vehicle ride height.
Includes:
- EDFC Controller Kit
- EDFC Motor Kit
* EDFC GPS Kits are available as an optional add-on!
EDFC Active Pro vs EDFC5 Comparison
Further Improvement in Cornering Performance
- Four-Wheel Independent Adjustment
EDFC ACTIVE adjusts front and rear damping force separately, but left and right simultaneously. With EDFC ACTIVE PRO, damping force for all 4 suspensions can be adjusted separately. This enables finer adjustment according to the road layout and conditions. This feature also works with automatic adjustment.
- Lateral G-Actuated Adjustment
While EDFC ACTIVE enables automatic adjustments based on changes in acceleration/deceleration (longitudinal) G-force and vehicle speed, EDFC ACTIVE PRO adds the capability to adjust to lateral (cornering) G-force change. This feature offers the advantages of ability to suppress side rolls, to balance distribution of left/right cornering loads and/or to increase cornering speed. In addition, understeering/oversteering can be controlled by adjusting front/rear damping force separately.
Acquisition of Vehicle Speed Data, Unaffected by GPS Reception Conditions
- External Input for Vehicle's Speed Pulse
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.
Added Control Functions Responding to Driver's Intention
- 2 Additional Input Ports for External Signals
EDFC ACTIVE PRO comes with 2 external input ports in order to meet such needs. While the signal is on, the damping force is adjusted to and stays at the preset level.
Operation Modes (ACTIVE PRO + EDFC5)
There is only one simple dial to set damping force to desired levels. Up to 10 presets are available to store and quickly recall preferred settings, according to the changes in situation.
- G-Actuated Automatic Adjustment Modes
- Lateral G-Actuated Automatic Adjustment Mode
This mode enables automatic adjustment according to the changes in lateral (cornering) G-force. 2 separate modes available; "G-Arrange Mode" to adjust damping force when G-force reaches the preset value (max 10 memories) each time, and "G-Linear Mode" to adjust linearly according to the preset G-force values, automatically supplementing the values in between.
-
- Longitudinal G-Actuated Automatic Adjustment Mode
This mode enables automatic adjustment according to the changes in longitudinal (acceleration/deceleration) G-force. 2 separate modes available; "G-Arrange Mode" to adjust damping force when G-force reaches the preset value (max 10 memories) each time, and "G-Linear Mode" to adjust linearly according to the preset G-force values, automatically supplementing the values in between.
- Speed-Sensitive Automatic Adjustment Mode
This mode enables automatic adjustment according to the changes in vehicle speed. 2 separate modes available; "S-Arrange Mode" to adjust damping force when vehicle reaches the preset speed (max 10 memories) each time, and "S-Linear Mode" to adjust linearly at all speed according to the preset points, automatically supplementing the values in between.
- G+Speed Integrated Control Mode
EDFC ACTIVE PRO can combine all 3 modes; longitudinal G-force, lateral G-force and speed.
Operation Modes (UNIQUE TO EDFC5)
The system learns driver's behavior and controls how jerk-reactive adjustment is made. Vehicle moves differently under different conditions; from highways, city streets, winding roads to racing tracks. AI works to determine and apply the most suitable adjustment patterns, eliminating sense of discomfort, for various driving situations.
By calculating jerk rate from changes in G-force detected, the system predicts how the vehicle will soon move and hence the adjustment can be made automatically at the very moment when the cornering, acceleration or deceleration starts. This makes it possible to strike a good balance between sharp handling and comfortable ride.
