Description:

The CTAP-001 Clutch and Throttle Position Activation Switch Module provides window switch activation based on most

common 0-5 volt sensor signals. The CTAP-001 is designed to connect to 0 to 5 volt DC sensors including most throttle

position sensors (TPS), accelerator pedal position (APP) sensors, clutch pedal position (CPP) sensors, brake pedal position

sensors and manifold air pressure (MAP) sensors. The CTAP-001 will accept either a rising or falling voltage signal.

The primary uses for the CTAP-001 are:

• Control the activation of nitrous systems based on throttle position

• Control the activation of a 2-step based on clutch pedal position

In nitrous applications the CTAP is normally used to disable the nitrous below a specified throttle angle. The CTAP allows

you do to this on most EFI engines without having to add a wide open throttle (WOT) switch. This is especially helpful

on electronic throttle equipped vehicles where no mechanical throttle linkage exists to connect a microswitch to. The TPS

based enable is normally used in conjunction with an RPM based enable/disable strategy using a Window Switch or a

programmable nitrous controller with built in RPM limit capabilities.

For 2-step applications, the CTAP is used to enable the operation of the 2-step based on clutch pedal position in newer

vehicles that have a clutch pedal position sensor. Vehicles such as the 2010-2014 Camaro, 2008-2013 Corvette and the

2009-2014 Cadillac CTS-V are equipped with a clutch pedal position (CPP) sensor. Unlike the clutch pedal switches found

on many earlier vehicles, the CPP sensor behaves much like a throttle position sensor. This means that it does not provide

an open or closed type contact that can be used to directly enable or disable a 2-step, relay or other device. The CTAP

takes the variable voltage signal from the CPP sensor and provides a programmable switched output that can then be

used to enable and disable a 2-step or other device. This also gives the added benefit of making it very easy to adjust

where in the pedal travel the 2-step activates.

Note the CTAP is usually not needed with the LPE NCC-001 and NCC-002 nitrous controllers since these devices can

accept a throttle and/or clutch pedal position sensor signal directly.

WARNING: The CTAP-001 can not be connected to the throttle position sensor on the new GM direct

injection V8 and V6 engines or other engines that use a digital throttle position signal. This includes

the 2014+ C7 Corvette (LT1 or LT4) and the 2014+ 4.3L, 5.3L and 6.2L Sierra and Silverado trucks.

On these vehicles the throttle position signal is no longer a 0-5 volt signal but is a digital serial data

signal. Contact LPE for alternative methods of obtaining a TPS signal on these vehicles.

Notes

Red

+12 Vdc

Connects to a switched and fused +12 volt DC source.

Orange

Normally

Off +12 Vdc

Output

This is the normally open (OFF) +12 Vdc activation wire. This wire will close the

+12 Vdc path when the switch is activated. This connects to the +12 Vdc side

of the device you plan to control.

Black

Ground

Connects to a vehicle ground.

Purple

Analog Input

This connects to the analog signal output wire of a Clutch Pedal Position

sensor, Throttle Position Sensor, Accelerator Pedal Position sensor, or other

rising or falling 0-5 volts signal sensors.

Gray

Normally On

Ground Output

This is the normally closed (on) ground activation wire. This wire will open the

ground path when the switch is activated. This connects to the ground side of

the device you plan to control.

Yellow

Normally Off

Ground Output

This is the normally open (off) ground activation wire. This wire connects to

ground when switch is activated. This connects to the ground side of the device

you plan to activate.
