This diagnostic tool, for Alfa Romeo diesel cars (MiTo, Giulietta, Giulia, Stelvio), was made to allow everyone to monitor the efficiency of emissions related systems. It is compatible with model year 2010+ cars with CAN bus diagnostic network. This tool is an independent tool not related with any car manufacture. Any reference to brand and model is purely by way of reference to allow the user an efficient diagnosis as provided by law.With this app you can monitor DPF (Diesel partuculate filter) status and regeneration, SS functionalities, Turbo, EGR, OIL status, read DTC (Diagnostic Trouble Codes), clear DTC and read some other informations of your engine ECU. The app supports a dashboard functionality to show you, in an elegant way, every day parameters useful during driving. On dashboard is always monitored the DPF regeneration status with a visual feedback during regeneration process.*** IMPORTANT ***This app doesn't connect to car Bluetooth, you need an external device to connect to OBD2 connector.For the moment the App is only compatible with Bluetooth ELM327 interfaces. The suggested interface is OBDLink LX Bluetooth, but the app can work with others models too if of good quality. A low cost interface that is working well is KONNWEI KW902.It's not recommended to use V-GATE interfaces and ELM327 Mini because it's tested that they use a fake with many bug ELM327 emulation not compatible with advanced OBD protocols.This App is not the common ScanTool that you can download from the market, is an advanced toot that need to comunicate with ECU in a particular way, so many Chinese cloned interface doesn't work, because of pore quality. The app is working very well if used with original ELM327 chip or with quality interfaces that emulates ELM327 protocol. With very cheap interfaces the app may not work, the problem is the hardware interface not the app.
