Unlike piggyback tuners, the PV4 modifies the factory ECU calibration — improving throttle response, removing speed limiters, and enabling tunes built specifically for aftermarket exhaust and intake configurations. The original factory tune is backed up and can be restored at any time, returning the bike to stock.\u003c\/p\u003e\n\u003ch3\u003eFeatures\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eBluetooth wireless flash tuning via the Dynojet mobile app (iOS and Android)\u003c\/li\u003e\n\u003cli\u003eAccess to Dynojet's library of pre-built tunes plus custom tune support from Authorized Tuning Centers\u003c\/li\u003e\n\u003cli\u003eQuicktune menu for one-tap control of active compression release, EITMS, VSS, knock control, and fan settings\u003c\/li\u003e\n\u003cli\u003eAutotune Basic uses factory O2 sensors; Autotune Pro available with optional wideband O2 module\u003c\/li\u003e\n\u003cli\u003eReal-time engine data logging viewable in WinPEP 8 Data Center\u003c\/li\u003e\n\u003cli\u003eLicense additional vehicles through the app without buying a new device\u003c\/li\u003e\n\u003cli\u003eFactory tune is backed up to the cloud and restorable at any time\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhat's Included\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003ePower Vision 4 Bluetooth tuning device\u003c\/li\u003e\n\u003cli\u003eOEM diagnostic port connector\u003c\/li\u003e\n\u003cli\u003eQuick start guide\u003c\/li\u003e\n\u003cli\u003eAccess to the Dynojet mobile app and cloud tune library\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eInstallation Notes\u003c\/h3\u003e\n\u003cp\u003eThe Power Vision 4 connects through the OEM diagnostic port and pairs to a smartphone via Bluetooth.
