The SS1 Speed Sync Unit is a compact signal conditioning module designed to convert variable reluctance (VR) sine wave speed sensor signals into a clean 0–5 volt square wave output. This allows factory or aftermarket VR speed sensors to interface seamlessly with modern electronic speedometers, engine management systems, data loggers, and other devices requiring a digital speed signal.
 
Engineered for reliable operation across a wide speed range, the SS1 cleans and conditions noisy analog sensor signals to produce a stable, accurate square wave output for consistent speedometer performance.
