When an upgrade to KW coilovers is performed, your vehicle’s original ECU electronic control module may not recognize the different operation and coding of your new components when it sends commands that affect the dampening. This broken loop of data can lead to confusion by the system, undue error messages, and even possible ECU failure. KW offers the Electronic Damping Cancellation Kit to address this issue. It’s a set of compact circuits that plug in and block dampening commands from your vehicle’s original ECU electronic control module. Only the factory damper signal is cancelled, leaving the electronic control unit fully functional otherwise. This kit is also usable for suspension made by other manufacturers, and it also works with original equipment aftermarket suspensions.
