Features / Specications:

• Designed for sequential or “H” pattern gearboxes

• ±500N / ±112lbf range

• Built-in amplifier

• Nylon outer cover

• M12 x 1.75 thread size/pitch (in and out for adapter version)

• ±0.5% accuracy

• 2.5V ±2.0V (bi-directional operation)

Load Cell Shifter Operation:

The Lingenfelter Performance Engineering (LPE) load cell shift knob and load cell shift adapter both
have bi-directional strain gauges installed inside of the devices that provides a signal that is caused
by a change in length of a resistor that is attached to the load cell. The change in length of the
resistor element in the load cell causes a change in output voltage across the load cell. At zero strain
the voltage across the load cell should be 2.5 V. When load (strain) is applied to the shifter, the
voltage will then become 2.5V +/- 2.0V. The maximum and minimum voltage across the load cell is
therefore 4.5V and 0.5V in tension and compression, respectively. Both LPE load cell shifter products
have a built-in amplier, alleviating the need for an external amplier.

Load Cell Shifter Installation:

Before the LPE load cell shift knob or load cell shift adapter can be wired up, the shift knob or shift
adapter must be screwed onto the shift lever. A 16mm open end wrench can be used to screw the
shift knob or shift adapter onto the shift lever. The LPE load cell shift knob and load cell shift adapter
are both designed to recieve their +5 volt reference (red wire) and ground reference (black wire)
signals from the same device that recieves the load cell’s signal, such as the LPE LNC-TC1 Launch
and torque cut controller (L460135297), or directly from an aftermarket Engine Control Module
(ECM). The 0-5 volt load signal (white wire) should be connected to the device that is providing the
torque cut, which could be a torque cut controller (such as the LPE LNC-TC1), an aftermarket EFI
unit, or a transmission controller. If it is necessary to lengthen the wires, use 26-24 AWG twisted
wires. You may have to adapt some of your other shifter components to the correct thread size and
pitch.
