BMDash is built for BMW drivers who want to see what their car is doing in real time. Connect your iPhone directly to the vehicle through ENET or a supported OBD Wi-Fi adapter and monitor live data from supported BMW control units — without creating an account or using a cloud connection for normal vehicle monitoring. SEE YOUR BMW LIVE BMDash brings important vehicle data together on a focused dashboard designed to be readable while driving, testing or diagnosing vehicle behavior. Depending on vehicle support, available data can include engine and transmission temperatures, boost pressure, RPM, oil pressure, fuel pressure, lambda, intake temperature, ignition timing, engine load, knock status and more. BUILD THE DASHBOARD YOU WANT BMDash PRO expands the available sensor set and allows the Dashboard to be customized around the information you want to monitor. Supported parameters can also display current, minimum and maximum values to make changes easier to track during a drive. ENGINE PERFORMANCE The dedicated Engine Performance screen provides a deeper view of engine operation. Supported vehicles can display: • Per-cylinder ignition timing • Per-cylinder misfire information • Boost actual and target • HPFP and LPFP pressure • Throttle position • Engine load • Lambda • Knock status EXHAUST FLAP CONTROL On compatible BMW vehicles equipped with supported factory exhaust flap hardware, BMDash can control the exhaust flaps directly from the app. DIRECT CONNECTION BMDash supports: • ENET • OBD Wi-Fi The app automatically identifies supported vehicles and control units where possible and selects the appropriate data configuration.

PRO includes Dashboard customization, additional vehicle data, Engine Performance, supported exhaust flap control and other PRO functionality.
