3. Overview
3.1. Product description
The Twister Electronic Throttle (p/n 119971) controls engine speed using a variable analog voltage connected to the
engine ECM for remote throttle applications. The Twister’s analog voltage range is 0.235 volts to 4.448 volts and the
minimum (idle) and maximum voltages can be configured between the standard range for specific engine
manufacturer requirements (refer to section 4.6).
The Twister utilizes Light Emitting Diodes (LED) to convey status information to the operator. The green THROTTLE
READY LED is on the left-side of the control knob and the blue ACTIVE LED is on the right-side of the control knob.
The Twister has a control knob and an idle button for the operator to control engine speed. The control knob allows
manipulation of the engine speed within the configured (and engine allowable) RPM range. The idle button returns
the engine speed to the configured idle RPM.
