Car Autoscanner Diagnostic ELM327 (Bluetooth Android) Mini OBD2 / OBD Autoscanner Car Diagnostics Version 2.1 PIC18F25K80 Review

The Elm 327 Obd2 Mini Bluetooth Autoscanner is an easy-to-use and effective device for diagnosing the condition of cars. Thanks to the use of the Bluetooth wireless protocol, the adapter is compatible with almost any smartphones, tablets, as well as personal computers, both stationary and portable. At the same time, ELM327 works with the automotive OBD2 protocol, which means compatibility with almost any of the modern car brands. Among the advantages of the OBD-2 diagnostic adapter based on the ELM327 microcontroller is compatibility with Android and Windows operating systems. The ELM327 scanner is also renowned for its fast and reliable connection to the control unit (ECU or ECU). ELM327 programs continue to work in situations where many other devices of this type fail. Obviously, the use of such a diagnostic tool can significantly save time and money on visits to service centers. And early diagnosis of a malfunction, as you know, allows you to ultimately minimize the cost of repairs, without allowing the malfunction to cause other related breakdowns of your car in time. What the ELM327 can do: detect almost any malfunction and identify its cause; clear the vehicle control unit from the consequences of software failures so that the burning indicators and sound signals do not persistently inform the driver about malfunctions that do not actually exist; read the parameters of the engine in real time. Through special programs, it is possible to control such parameters of the engine operation as: revolutions calculated load power (actual and potential) torque mains voltage coolant temperature intake manifold pressure mass air flow (MAF) vehicle speed calculation of acceleration time (0-100 km / h ) calculation of deceleration time (110-0 km/h) oxygen/fuel ratio ambient air temperature CO2 emission residual fuel fuel delivery correction instantaneous fuel consumption short-term fuel consumption long-term fuel consumption absolute air pressure intake air temperature injector advance angle throttle position lambda parameter values - rail pressure probes and so on. OBD-2 protocols supported by ELM327 adapter: SAE J1850 PWM SAE J1850 VPW ISO 9141-2 ISO 14230 KWP2000 ISO 15765 CAN
