STOV-002 basic operation description:
Input and output wires (see wiring table on page 5):
The vehicle speed input signal to the STOV is Engine Control Module (ECM) or Powertrain
Control Module (PCM) pulse per mile (PPM) signal from most newer GM and other vehicles. The
STOV will accept 2000, 4000, 8000 or 10,000 pulse per mile square wave 12 volt DC vehicle speed
signals.
Analog voltage output is a 0-5 volt DC analog output proportional to speed. Speed range is 0 – 250
MPH (0 volts = 0 MPH, 5 volts = 250 MPH). Analog output will increase at a rate of .02 volt per
MPH (linear relationship between speed and voltage). The analog voltage output function operates
the same in all modes for each given frequency setting.
The analog voltage speed output can be used to feed vehicle speed to auxiliary data acquisition
systems or to feed vehicle speed to devices that are not able to read the vehicle speed pulse data
directly (some boost and nitrous controllers).
Two Ground active outputs. These outputs can either be simulated stage/gear position pulsed outputs
or can be vehicle speed activated normally open and normally closed switched control wires.
Switches (see switch position image on page 5):
16 position Function switch to select operating mode.
16 position Range switch to select output configuration.
The STOV-002 can be used to:
• Disable the fans above a certain vehicle speed.
• Lock Torque Convertor Clutch (TCC) above a certain vehicle speed.
• Enable a second stage of boost or nitrous above a certain vehicle speed.
• Trigger a buzzer or warning light above a specific vehicle speed (Over-speed warning)
• Activate the door locks above a certain vehicle speed.
• Virtually any other device that needs to be turned on or off at a certain vehicle speed.
