Defi-Link Meter ADVANCE BF Features Include: - Interactive communication advanced system is implemented. - Flat glass and precise graduation scale give more needle accuracy and high visibility. - Gauges can be controlled from distance with the included switch unit. - Opening and closing modes can be selected from 2 variations. - The installation of additional gauges is easy. Just connect it with theother two gauges and attach the wire to Advance Control Unit. - The illumination color can be chosen from white, amber red, and blue. - The light-emitting gauge always provides clear visibility with high contrast.(The brightness is 200% compared to existing models.) - The needle pointer driven by original stepping motor has a smooth instantaneous response to rapid acceleration of high performance vehicles. - Brightness can be adjusted by selecting from five levels for daytime and nighttime separately.(nighttime dimming cancellation function is available.) - The microcontroller calibrates up to 270 degree angle in 3027 - 4600 segments (0.088°- 0.059°), and provides accurate vehicle information. - Self-diagnosis system turns the warning LED on to indicate any wire disconnection, short circuit and serial communication errors. - Warning by buzzer sound when the warning LED is on (buzzer sound can be turned on / off). - Peak value and warning value during driving are stored. Driving data can be stored and replayed up to 3 minutes. - A mounting bracket, meter cup, regular position bezel are provided with this product. - With both fuel pressure gauge and turbo installed, differential pressure can be monitored on the fuel pressure gauge screen. **NOTE: Defi-Link ADVANCE SYSTEM is the next generation system that adopted the interactive communication. The product of Defi-Link ADVANCE SYSTEM cannot be connected with the product of Defi-Link SYSTEM. It is not compatible with the product of Defi-Link SYSTEM. Defi-Link ADVANCE Control Unit is necessary to operate ADVANCE BF Meters.
