The TPRS-002-LV Window Switch provides a +12 volt output that is controlled by RPM and/or a 0 to 5 volt signal such as Throttle Position or Gear Position. This unit can be connected to the Gear Position or Throttle Position sensor and/or RPM input to activate a nitrous system. This can be configured to activate a nitrous kit at 8,000 RPM and when the throttle is great than 90%. It will also de-activate the nitrous system when you reach a preset RPM (just before the rev-limiter is recommended). Or, you can choose to activate the system based on gear position. Great for those wanting more consistency or for those who want to wait and have their nitrous kit come on in 2nd or 3rd gear.
The Throttle Position Input has been designed to tolerate a +12 volt input signal. The allows a Typical, Mechanical Nitrous Wide Open Throttle Switch to be used with the RPM Window Switch function. (This is recommended for those who want to set this up for gear position activation)

The TPRS-002-LV has been designed to work with several different types of engines. There are five different RPM Input options for each of the three RPM ranges.
1--One input pulse for every two crankshaft revolutions. (Newer Sportbike)
2--One input pulse for each crankshaft revolution. (typical single and twin cylinder)
3--Two input pulses for each crankshaft revolution. (typical 4-cylinder operation)
4--Three input pulses for each crankshaft revolution. (typical 6-cylinder operation)
5--Four input pulses for each crankshaft revolution. (typical 8-cylinder operation)
The TPRS-002-LV provides three different RPM ranges.
Low Range - 3,000 RPM to 9,250 RPM in 250 RPM increments
Mid Range - 6,000 RPM to 12,500 RPM in 250 RPM increments
High Range - 6,000 RPM to 16,000 RPM in 500 RPM increments
*Note - The ZX-14 GPS starts with a high volts and decreases with each gear change. The TPS-002-LV can not be connected to the GPS as described above.
