Oil, gearbox, boost and revs on a screen you lay out yourself in CarPlay — on a BMW and MINI, from the engine and gearbox units themselves; on most other cars, the standard OBD readings they report.

On the car’s screen
One morning, told by the screen that rode along.
· Ignition
Dashes first, then the numbers.
Plug the adapter in once. When CarPlay connects, Tachwire finds it, recognises the car from its answers and VIN, and each tile fills as its unit answers. Nothing to press.
· Warm-up
Oil 41°. Blue means wait.
Oil, coolant and gearbox count down to ready, and the screen says how long and up to what revs: below 50° oil, 3,000 rpm. Thresholds are your car’s own.
· On the road
Green. Ready.
Gear, speed, oil pressure and the tyres, each from the unit that measures it; the screen updates twice a second. If oil pressure drops, a voice says so — in eleven languages, made on the phone.
· Road cameras
“Speed camera, 120.”
Speed cameras, average-speed sections, low-emission zones and Italy’s ZTL gates — said out loud where the law allows it, with a window on the car’s screen. Off until you turn it on.
· Closed track
−0.4 s to your best.
Laps time themselves at the line; the gap lives on its own page, never on the map. Records count only full-throttle runs.
· Parked
The drive, judged against your car’s usual.
Every reading on one time line, a verdict with its reason — oil warmed in 3 minutes, usually 16 to 20 — and a 15-second video to share. Sending a drive is your choice; the route is cut out on the phone first.

Privacy
Your routeis cut out on the phone.
No account
No sign-up, no ads. The app works the moment it’s installed.
Sent only if you choose
A drive leaves the phone only if you turn sending on — encrypted, with latitude, longitude and heading removed first. Only laps on a track keep their positions. Kept 30 days.
Made on the phone
The voice is made on the phone, and the camera lists live there: once a country is downloaded, alerts need no signal, and your position isn’t sent to find them: only which country’s list to download is asked for.
The phone app opens and shows past drives, but it reads the car only while CarPlay is connected.
Will it work on my car?
Most likely, if it was built from 2008 on: most cars since then speak CAN on the OBD port and get the standard readings — revs, speed, coolant and intake temperature, and more where the car reports it — with the tiles, warnings, laps and runs. BMW gives the most: the G-series and F-series are recognised from the VIN and confirmed model by model on real drives. MINI: the John Cooper Works Clubman (F54) is confirmed on its drives. Audi A3 (8Y) and Mazda3 (BP) are confirmed by drives too. Other Audi and Mazda models, and Mercedes-Benz, Porsche, Ford, Toyota, Lexus, RAM, Dodge, Jeep, Chrysler, Land Rover, Jaguar, Volkswagen, Škoda, SEAT / CUPRA, Lamborghini, Bentley and Honda, get trial profiles: the app asks them, or some of their models, for more, and a reading counts as working only once a drive log has shown it. The cars page says what each one reads.
Can it change anything in my car?
No. It only reads live values. No fault codes, coding or service resets.
Does it work with a Dragy?
Not in the App Store version yet. The DRG70 works in the TestFlight builds, where with a good fix it times your runs; it comes to the App Store once testers’ drives have proven it.
What leaves my phone?
Nothing about your drives unless you turn sending on — encrypted, with the route removed (only laps on a track keep their positions). Crash reports turn off with one switch.
