What are your thoughts on Active suspension?

The link shows what is below allot better
http://www.tein.com/products/edfc_active_pro.html







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. (Patent Pending)
 
* This product does not adjust vehicle ride height.

EDFC ACTIVE & EDFC ACTIVE PRO Users Forum Facebook Page. Please use this forum to publish & share setting data and/or to explore & discuss about usage examples, ideas & tips.
Setup sheet is available in Excel and PDF formats. Please download from the links below.



[Concept 1] 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.

      
Four-Wheel Independent Adjustment       Front/Rear Separate & Right/Left Simultaneous 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.
This lateral G-actuated adjustment can be combined with longitudinal G-actuated adjustment for a full 360-degree adjustment and/or with speed-sensitive adjustment for most comprehensive adjustment.
This is useful not only for improving times on tracks/circuits and drivability, but also for daily driving as stable cornering can probably have positive effects on reducing burden on drivers and on minimizing tire abrasion.



      

[Concept 2] 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.

      

[Concept 3] Added Control Functions Responding to Driver's Intention

■2 Additional Input Ports for External Signals
EDFC ACTIVE brought the automatic damping force adjustment into reality, but there are customers asking more.
"I want to have more control over the car."
"I want to give my own cue, independent of G-force and speed change."
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.
For example, it can be connected to the parking brake signal for better drifting, to a universal switch to turn it on when the driver sees the slippery surface, and so on. Each and every driver can use these ports as he/she likes, for wider varieties of purposes.

Examples of Use for External Inputs
      
Connected to Parking Brake Signal      Connected to Universal Switch (not included)



●Manual Mode
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.

Examples


●G-Actuated Automatic Adjustment Mode
■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.
For example, damping force is set to softer level while running on street roads to absorb unevenness on road surface smoothly and set to harder when cornering to suppress side rolls for smoother handling and ride comfort.
On circuits, understeering/oversteering can be controlled by setting damping force to increase stability while braking and setting up front/rear damping force separately to correspond to degree of acceleration/deceleration.
*Damping force is adjusted by the set value (relative value) from the manually set level according to the changes in lateral G-force.

■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.
For example, on streets, damping force is set to softer level while driving at constant speed to absorb unevenness on road surface smoothly and set to harder level when accelerating/decelerating to suppress unnecessary vehicle movement for better handling and ride comfort. On circuits, understeering/oversteering can be controlled by setting damping force to increase stability while braking and setting up front/rear damping force separately to correspond to degree of acceleration/deceleration.
*Damping force is adjusted by the set value (relative value) from the manually set level according to the changes in longitudinal G-force.

●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.
For example, on streets, damping force is set to 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 circuits, 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.
*Speed-sensitive adjustment program for EDFC ACTIVE PRO differs from that for EDFC ACTIVE, as the former adjusts by the set value (relative value) from the manually set level while the latter adjusts to the set value (absolute value). Refer to the manual for further details.

●G+Speed Integrated Control Mode
While EDFC ACTIVE combines 2 modes; longitudinal G-force and speed, EDFC ACTIVE PRO can combine all 3 modes; longitudinal G-force, lateral G-force and speed.

●3 Damping Force Adjustment Modes
Damping force adjustment levels can be set in 3 different types; 16-level, 32-level or 64-level. Most TEIN damping force adjustable dampers come with 16-level adjustment. Use of EDFC ACTIVE PRO adds 32-level and 64-level adjustment capabilities within the same range for finer adjustments especially in automatic adjustment modes.

Soooo - what's it like? Saw you posted that you've got it in and running on another thread - but really interested to hear more about how much, how hard and whether it's worth the investment?
C'mon, do it!

I have only driven with it twice at this stage and that was also with new Tyres and suspension.

I will have a better idea after next weekend and will do a review.
I only had the front and back on this weekend and plan to have all 4 corners working individually.

But i think it will be good. The car was tight and pointed really well. Also more comfortable than before when set to soft.

Sounds great, thanks for the reply mate. Look forward to hearing more as you experiment with the setup.
C'mon, do it!
