What makes our iVSS the best vehicle speed sensor replicator on the market? Its integration with the iWire Connect App, precise calibration, easy-to-install plug-and-play wiring, and ability to work with MPH and KPH speedometers. 

Transmission Swap from a Newer Vehicle

Most available transmissions come from 2005 and newer Legacy and Outback models, 2008 and newer Impreza models, or 2009 and newer Forester models. These transmissions are all CANbus-based and do not include vehicle speed sensors. This lack of a speed sensor poses a challenge for older vehicles, such as the 2002-2007 WRX, which are not CANbus-based. These older models require a mechanical gear within the transmission that spins a sensor to generate a signal that the ECU and cluster can understand.

Broken Speedometer Gear

Don't spend a fortune to pull the transmission, tear it apart, and replace the gear. Instead, just utilize the VSSPro and you'll be back to reading speed in no time for far less expense.

Bigger Tires, No problem.

Accurate speed sensors can be a challenge for the overlanding crowd. With our built-in calibration tool and the iWire App, you can easily match the speedometer to an accurate vehicle speed.

Tired of translating KPH to MPH with your JDM Cluster?

If you are tired of translating KPH to MPH on your JDM cluster, we have a solution for you, too. During the unit's setup, you can choose to have the cluster's output read in MPH time, eliminating this problem.

iWire App Connectivity

Long gone are the days of little set screws, wonky dials, and not knowing if the unit is even on. Get the iVSS installed and powered up. Then log into the iWire Connet app (IOS and Android) to set up the unit as well as calibrate the output to the speedometer and ECU for your tire size with an easy-to-use GPS-powered interface.
