Tein EDFC Active Pro + GPS

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) [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. - 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. - 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.
