DigiTune DBW Throttle Driver

Description

The DigiTune DBW Throttle Driver is a standalone module capable of controlling a drive by wire throttle with high speed and precision.

Position demand input can be taken from any of the following sources:

• Pedal position sensor
• CAN signal from ECU
• Digital PWM signal from ECU (5V, 12V or Low Side Driver)

Features:

• USB-C port for connection/configuration
• Fully configurable with pedal to throttle position mapping
• Auto Calibration through software
• 4kHz control loop for high precision control
• 10A current rating ensures maximum performance with all throttles
• Can also be used for DBW bypass valve control

The configuration interface is shared with the DigiTune Fusion (an IO expander capable of controlling two DBW throttle bodies)
