Features
The Twister Electronic Throttle is an SAE J1939 Controller Area Network (CAN) or Analog device that controls engine speed using data communications directly to the engine ECU for remote throttle applications. Control algorithms are optimized to take advantage of the J1939 CAN data to yield crisp and accurate control of engine. For engines that may not support the J1939 CAN data link control, an analog output signal version of the Twister Electronic Throttle is available (p/n 119971). 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.Applications/Solutions
