Feature:1. Function: Support most all of J2534 compatible software, most all of for ELM327 software, ECU reprogramming in J2534 mode with programming voltage, supply free software for diagnosing J1979 compatible vehicles.2. Detail Introduction: VNCI (Vehicle network communication interface) is a device that works between diagnostic software and vehicle. It is compatible with J2534 Passthru and for ELM327.3. Support Protocol: VNCI J2534 for Nano protocol configuration include, for ISO15765, for ISO9141, for ISO14230, for J1850 PWM( supports IFR and 2X speed modes), for J1850 VPW (supports 4x speed mode).4. Features: Support J2534 and for ELM327 mode in one device, and has automatic switch mode, more speedup, faster communication and reprogramming.5. Advantages: More stability, never let you down while reprogramming, portable and convenient, small package and easy to carry.Specification:Item Type: Car Diagnostic ToolsMaterial: ABS1.VNCI J2534 for Nano Compatible with J2534 Passthru and for ELM327 Diagnose J1979 compatible vehicles switch mode automatically2.VNCI (Vehicle network communication interface) is a device that works between diagnostic software and vehicle.
