What Is A Speed Limiter?

This is a Speed Limiting Device(SLD) to electronically control the maximum speed without affect engine power and the vehicles’ normal operation. At a pre-set maximum speed, for example 80km/h, Sabo speed limiter will prewarn at a speed 5% less than pre-set speed for warning drivers, when the vehicle reach at pre-set speed 80km/h, the ECU will transmits a signal to Engine Management System which will control the vehicle’s maximum speed. The vehicles’ travelling data,incluidng gps vehicles tracking,speed,date,time will be recorded and could be save as PDF format.
