## What is TunerView Pro?

IMPORTANT!!! – Neptune, eCtune, Crome, Hondata S300, Nismotronic and QuarterHorse Protocols REQUIRE SPECIAL BLUETOOTH LE MODULES
On iPhone and iPad this protocol works ONLY with a special Bluetooth LE (BLE) module. Older Bluetooth modules (classic Bluetooth / SPP, e.g. HC-05, HC-06) do NOT work on iOS.
Please contact the manufacturer of your Bluetooth module for information about a compatible module before purchasing.

TunerView Pro turns your phone or tablet into a fully customisable digital dash and datalogger for tuned cars.

Connect to your ECU over Bluetooth or WiFi and see every important value live: RPM, boost, AFR / lambda, coolant and oil temperature, ignition timing, knock, injector duty and many more.

LIVE DASHBOARD
• Analog, arc, sweep (S2000-style), bar, digital, LED, gear and shift-light gauges
• Ready-made layouts in classic TunerView style, portrait and landscape
• Layout editor: drag, resize, colours, fonts, warning limits, background image, your own logo
• Export, import and share layouts with your friends
• HUD mode – mirrored display for the windscreen

DATALOGGING
• Record every channel with one tap, up to 50 Hz
• Built-in log viewer with charts, CSV export and sharing

CAMERA MODE
• Record video with the live dashboard overlaid on the picture

PERFORMANCE & TRACK
• Acceleration timer: 0-60 mph, 0-100 km/h, 0-200 km/h, 60-130 mph, 100-200 km/h, 1/8 mile, 1/4 mile, 1000 m
• Lap timer with start/finish line, saved tracks and live delta
• Phone GPS speed for every protocol, or a RaceBox Mini / Mini S / Micro for 25 Hz GPS

LIVE ACTIVITIES & CARPLAY (iOS)
• Selected values on the Lock Screen, in the Dynamic Island and on the CarPlay dashboard (iOS 26+), also while the app is in the background

Hardware note: TunerView Pro needs a compatible Bluetooth / WiFi adapter or interface for your ECU (for CAN protocols a CAN adapter such as OBDLink). The app only reads data – it does not change your ECU's tune.
Use the app responsibly. Do not operate the phone while driving; mount it securely. Performance and lap timing are intended for closed tracks only.
