BMDash Pro vs Tachwire

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. TRY IT WITHOUT A CAR Demo Mode allows you to explore the BMDash interface and dashboards without connecting to a vehicle. BMDASH PRO BMDash PRO is a one-time in-app purchase — no subscription required. PRO includes Dashboard customization, additional vehicle data, Engine Performance, supported exhaust flap control and other PRO functionality. REAL-WORLD DEVELOPMENT BMDash is actively developed and regularly improved with new features, vehicle support and refinements. Development and real-world testing are performed using a BMW M5 Competition (F90), helping validate connection behavior, live vehicle data and app functionality in actual use. Vehicle data and feature availability depend on model, model year, installed control units, software configuration and connection method.

Tachwire reads your car through a Bluetooth LE OBD adapter and puts what the dashboard keeps to itself — oil and gearbox temperatures, boost, gear, a hybrid's battery, on a BMW even oil pressure — on the car's screen, laid out the way you want. When something runs critically hot, it says so out loud. A SCREEN OF YOUR OWN IN THE CAR • Tiles of any size on a grid fitted to your car's display. • Pages for the road, the track and the warm-up, a button apart. • Arrange it on the phone, start from a layout in the Gallery, or edit on the car's screen while parked. • A Live Activity on the Lock Screen, in the Dynamic Island and, on iOS 26, in CarPlay. YOUR CAR AND YOUR DRIVES • Car: your car pictured in its factory colour; tank, battery, tyres and the last drive at a glance. • Drives: a diary by day — city, highway or track, with alerts, pulls and records. • A drive's page: the route, a verdict with its reason, every reading on one time line. • Logbook: records and trends against your car's own usual; ignition timing pull and power by rpm. • Power from the torque the engine reports, never estimated. 0–60 mph or 0–100 km/h, ¼ and ½ mile, timed from the car's speed — on a closed track only. ROAD CAMERAS • Spoken alerts and a map window on the car's screen for speed and red-light cameras, section controls and low-emission zones in Spain, Portugal, Italy, the United Kingdom, Poland, Austria, Belgium, Bulgaria, Norway, the Netherlands, Czechia, Cyprus, Malaysia and Russia. France: danger zones and low-emission zones only, as French law allows. Silent where such alerts are banned. • Off until you turn it on. TRACKS • 535 tracks in 17 countries, or set your own start/finish line. • Laps by session and the gap to your best, on the car's screen too. Runs and laps only on a closed track. • Track guidance in CarPlay: on a circuit, the track map with the next turn, and your braking points once a lap is recorded. A Track map tile for any page. WHICH CARS • BMW, the deepest: G-series from 2018 and F-series, recognised from the VIN — oil temperature and pressure, gearbox temperature and gear, boost, torque and power, a plug-in hybrid's e-motor and battery, a diesel's DPF and AdBlue. • MINI (2014–2024) and the Toyota GR Supra are read the way a BMW is. • First support, readings vary by model: Mercedes-Benz, Porsche, Ford, Toyota and Lexus, RAM, Dodge, Jeep, Chrysler, Land Rover, Jaguar, Audi, Volkswagen, SEAT, CUPRA, Mazda and Honda. Renault, Dacia and Alpine are recognised. • Any other car with an OBD port: revs, speed, coolant, intake, load, often oil temperature and boost. A tile stays empty rather than show a wrong number. Make by make: tachwire.app/cars. WHAT YOU NEED • A Bluetooth LE OBD adapter: OBDLink CX (the fastest), vLinker, UniCarScan, or an ELM327 BLE clone (slower). Classic Bluetooth and Wi-Fi adapters can't connect to an iPhone. • iOS 18.4 or later and CarPlay, wired or wireless: the app reads the car only while CarPlay is connected. • No adapter yet? Choose "No adapter yet" on the first screen: which one to get, and a demo drive. READ-ONLY, PRIVATE Tachwire only reads live values: no fault codes, no coding, nothing changed in the car. No account, ads or tracking. Drives stay on the phone unless you turn sending on (encrypted, route removed; only laps on a track keep their positions). Crash reports turn off with one switch; usage data only if you agree. GPS runs only during a drive. SUPPORT TACHWIRE Everything in the app is free. Monthly coffee and Monthly burger are optional monthly subscriptions, a thank-you to the developer, with car looks: a playful picture for the Car card and your pick of its trim and colour; every figure stays your car's.
