Note: Monsoon and Storm ECUs can control an EThrottle using an external controller, Xtreme and Fury ECUs can control an EThrottle with either the internal controller or an external controller. Information on the Link controllers can be found here.
The Electronic Throttle Control (E-Throttle) Function provides the user with total control of an electronically actuated throttle plate. The system includes multiple 3D tables to allow for multiple switchable setups, Diagnostics and failure detection to ensure safety, auto calibration functionality for both the throttle position and accelerator position, Idle Speed Control integration, Anti-Lag integration and more.
The G4X E-Throttle system is designed to work with the majority of factory throttle actuators as well as a variety of aftermarket electronic throttle actuators and position sensors. Up to three 3D tables are provided to allow the tuner to customize the actual throttle opening based on driver accelerator position, engine speed or a variety of other variables and to switch between different setups at will.
Safety is the most important requirement of Electronic Throttle Control, the ECU utilises a dual redundancy system (two throttle position sensors and two accelerator position sensors) to ensure the throttle plate is under control at all times. The system is continually monitored for potential faults, and on detection of any faults the system will be shut down.
WARNING: Electronic Throttle Control is an advanced feature and should only be used by an experienced installer and tuner. DO NOT attempt to configure any part of the Electronic Throttle Control system if you are at all unsure or do not have sufficient experience to do so.
WARNING: Every effort has been made to ensure that the Electronic Throttle Control system is reliable and safe. However, incorrect installation, wiring and setup can cause unexpected throttle operation. If at any stage you are unsure, immediately contact your Link dealer for advice. Link provides Electronic Throttle Control functionality 'as is' and accepts no responsibility for the use of Electronic Throttle Control or any consequential damage that may directly or indirectly arise from the use of Electronic Throttle Control.
WARNING: The electronic throttle mode 'Setup Mode' is provided only for configuring the system with the engine not running - all safety features are disabled. The vehicle MUST NOT be driven in 'Setup Mode' mode.
Requirements
The following hardware is required for a working Electronic Throttle Control installation:
1.An ECU supporting E-Throttle (either internally or with external controller).
2.An electronic throttle actuator, the actuator must be driven by a DC motor and must be able to be driven over the entire range of throttle plate movement. Note that some actuators only allow the throttle plate to be driven closed (i.e. for traction control).
3.A dual throttle plate position sensor (TPS). This sensor should be 5V supplied with two differently spanned output signals.
4.A dual accelerator pedal position sensor (APS). This sensor should be 5V supplied with two differently spanned output signals.
5.An isolating relay to disconnect the Aux 9/10 supply voltage.
It is absolutely essential that all Electronic Throttle Control wiring is as per the wiring and installation manual diagrams. All sensors must be grounded correctly to the ECUs sensor ground and an ECU controlled isolating relay installed. Note that most factory vehicles will be wired in a similar manner. DO NOT power the ECUs Aux 9/10 (for E-Throttle 1) power supply pin (or external controller) until the ECU has been configured for Electronic Throttle Control operation. Doing so may result in the throttle plate being driven hard open or closed which may damage the throttle actuator motor or blow fuses.
