TEIN EDFC ACTIVE Controller: Suspension tuning at its best

,

While you can hear the shock motor units adjusting, at least in the case of the Supra they’re so quiet that I’m only sometimes reminded they’re there when I turn the key to “on” without turning the engine over. I don’t hear them when the MKC-tuned 2JZ is idling, however.

If you don’t opt for the GPS-based system, the EDFC ACTIVE and ACTIVE PRO comes with a signal converter to tell the display unit what the vehicle speed is.

Our Project MKIV Supra, however, is using the GPS-based system, which is a worthwhile upgrade.  Installation of this small unit is easy—we just put it inside at the base of the windshield.

TEIN did a superb job in coming up with a display unit that is both up-to-date, ergonomic, and compact. Because of its small size, there are many possible install locations. In the case of our Supra, we put it in the center console compartment because we don’t expect to be constantly adjusting it, thanks to its GPS/MPH customization capabilities.

The dimensions of the EDFC ACTIVE display unit measures 98mm x 40mm x 0.8mm, which converts to 3.9-in by 1.6-in by 0.8-in. It’s pretty small indeed.

Depending on where you mount it, TEIN made it easier to be able to hide the wiring by allowing you to run the wire down, left, right, or even straight back so that the unit stays flush against whatever surface it’s secured to.

TEIN still sells the original EDFC we used to run on the Supra, and the firm sells it for a bargain today.  TEIN reports it’s sold over 100,000 of these units, too.  As you can see, it had three preset channels but you had to toggle them on the fly (say for “soft”, “sport” and “race”).  The unit is also much larger than the EDFC Active.
