Lingenfelter Performance Engineering STOV-004 Vehicle Speed Based Switches

The Lingenfelter Performance Engineering STOV-004 is a vehicle speed-based switch that can be used to enable or disable devices based on vehicle speed—much like an RPM switch or RPM window switch, but instead based on vehicle speed. The STOV-004 also provides a 0-5 volt analog output corresponding to vehicle speed that can be used to provide a vehicle speed signal to many other add-on devices.

These switches can accept the vehicle speed output signal from most engine control modules and can also connect directly to many common speed sensors. The Lingenfelter STOV-004 can also provide a stage/gear shift output for boost controllers and other devices that need to see a gear shift position switch output to change stages.

Product features:

* Accepts a wide range of pulse count frequencies from 100 to 60,000 pulses per mile (PPM)
* Works with ECM output signals and stand-alone Hall effect-type speed sensors
* Easy-to-use vehicle speed learning mode using push-button switch in the back of the module
* Set the PPM count even when you do not know the PPM configuration of the vehicle
* Built-in vehicle speed sensor signal pull-up resistor that is enabled by a DIP switch setting inside the back cover for applications that require a pull-up resistor
* Simplifies wiring
* Easy to adjust high and low vehicle speed settings via four front-mounted 10-position switches
* Provides switched outputs or window switch outputs based on vehicle speed
* Provides ECM/PCM vehicle speed frequency to analog voltage conversion

Available output types:

* Normally ON ground
* Normally OFF ground
* Normally ON +12vdc
* 0-5vdc/0-250 mph linear analog output

Stage/gear shift output mode works with multi-stage boost and nitrous controllers including:

* Turbosmart eBoost2
* NLR AMS1000
* Leash Electronics Boost Leash Gear-Based controller

Benefits:

* Easily adjustable activation point in 1 mph increments
* Enable nitrous or an additional stage of nitrous-based on vehicle speed
* Enable a boost controller for increased boost above a certain vehicle speed
* Disable fans above a certain vehicle speed
* Lock a torque converter clutch above a certain vehicle speed
* Disable a 2-step once the vehicle is moving so that it does not activate on each gear change
