ELECTRONIC RATIO ADAPTER (ERA)
The Electronic Ratio Adapter (ERA) is a universal speedometer signal interface that is designed to easily recalibrate your electronic speedometer after a change in your vehicle's tire size or rear axle ratio. The ERA is a "speedometer calibrator" that receives your current speedometer signal from your vehicle speed sensor (VSS) and will recalibrate to the correct speed signal.
