VC4000DAQ Performance Computer "Internal 10Hz GPS and automatic pitch adjustment"
Over 25 years of research and development have gone into the design of the Vericom VC4000DAQ making it the most innovative instrument for measuring tire to road friction and vehicle performance. Vericom’s reputation for excellence is truly displayed within the workings for the VC4000DAQ. Vericom is known world-wide for its accuracy in calculating vehicle speed and distance from acceleration and time. Used by accident reconstructionist and transportation authorities because of its accuracy and acceptance into court. Vericom is the only performance computer in its price range that can accurately synchronize acceleration, speed, time and distance during vehicle braking which is partially due to Vericom’s RDP ™ (Run Duration Protocol). Now with OBDII CAN and 10Hz GPS interface the VC4000DAQ is its own working test module allowing the Vericom speed to be easily confirmed.
