The Defi-Link ADVANCE Control Unit SE (model DF17701) is a sophisticated control unit designed to integrate and manage up to seven ADVANCE gauges and displays, enhancing a vehicle's monitoring capabilities. This device is part of the ADVANCE system, which features interactive communication between the control unit and connected gauges.
Function Description
The primary function of the Defi-Link ADVANCE Control Unit SE is to serve as the central hub for the ADVANCE system, allowing for the connection and control of multiple ADVANCE gauges. It processes sensor data from various sources (such as fuel pressure, turbo pressure, and differential pressure) and transmits this information to the connected gauges for display. The unit supports both fuel pressure and turbo sensors, as well as differential pressure, providing comprehensive monitoring.
Key functionalities include:
- Gauge Control: Manages up to seven ADVANCE gauges, enabling them to display various parameters.
- Opening and Ending Modes: Offers two selectable modes ("A" type and "B" type) for the gauge startup and shutdown sequences, which can be configured via dip switch 2 on the control unit.
- Self-Diagnosis System: Detects disconnections in wiring, short circuits, and communication errors, and indicates these conditions via error codes.
- Warning Value Setting: Allows users to set warning values for each gauge. When a parameter exceeds the set warning value, the warning LED on the gauge illuminates, and a buzzer sounds (which can be turned ON/OFF).
- Real Peak Mode: Records and displays the maximum and minimum values of various parameters (oil pressure, fuel pressure, differential pressure) during driving and idling. These peak values can be reset.
- Illumination Control: Provides five levels of brightness for daytime and nighttime illumination, which can be adjusted by pressing the [RIGHT button] on the switch unit. The illumination color for RS/CR gauges can be selected from two colors (amber red or classic white), and A1/BF gauges also have two illumination colors (bright or dark).
- Differential Pressure Display: Displays the differential pressure value between fuel pressure and intake manifold pressure. During Real Mode, the indicator of differential pressure on the switch unit lights up in blue.
- Cylinder Setting: Allows setting the number of cylinders for ADVANCE tachometers (default is 4 cylinders).
- Tachometer Response Setting: Offers three levels of response (high, middle, low) for the ADVANCE tachometer.

Usage Features
The Defi-Link ADVANCE Control Unit SE is designed for ease of use with several features that enhance the user experience:
- Simple Connection: Gauges are connected to the control unit via a single line, simplifying wiring. Up to 7 gauges can be connected to one control unit.
- Switch Unit: Includes a separate switch unit for controlling various functions, such as setting warning values, adjusting illumination, and operating Real Peak Mode. The switch unit features left, middle, and right buttons, and a slide switch for REAL/PLAY/SET.
- Visual and Audible Warnings: Provides both visual (warning LEDs on gauges) and audible (buzzer) alerts when set warning values are exceeded.
- Display Modes: Supports various display modes including opening/ending modes and Real Peak Mode.
- Illumination Adjustment: Allows for easy adjustment of gauge illumination brightness for optimal visibility in different lighting conditions.
- Error Detection: The self-diagnosis system helps identify and troubleshoot wiring and communication issues, making it easier to maintain system integrity.
- Installation Flexibility: The control unit can be mounted using nuts and bolts, and commercial mounting brackets are available.
