An Android instrument-cluster app for Honda engines running a Hondata K-Pro V4 ECU, connected over USB-OTG. Designed to be mounted in the car as a digital dashboard.
This is an independent Android port inspired by the original HonDash (Raspberry Pi / Python) project.
- Live ECU polling over USB-OTG (K-Pro V4).
- Configurable tile dashboard:
- 2 × 2 grid, multiple pages, long-press to configure, tap "+" to add.
- Sources include RPM, ECT, IAT, TPS, MAP, AFR, battery, VSS, gear, and 8 generic analog inputs (AN0–AN7).
- Per-tile unit selection (e.g. °C/°F, psi/bar, km/h/mph) and custom label override.
- Per-tile warning / alarm thresholds, with a hard-flashing alarm state.
- Per-analog-channel linear calibration (e.g. 0.5–4.5 V → 0–100 psi).
- Demo mode that drives every tile from a synthetic ECU, no hardware required.
- Layout, thresholds, and calibration persisted across launches.
- Android device with USB-OTG support, Android 8.0 (API 26) or newer.
- Hondata K-Pro V4 ECU and a USB-OTG cable.
- For development: JDK 17 and Android Studio (or the included Gradle wrapper).
./gradlew assembleDebugThe debug APK is written to app/build/outputs/apk/debug/.
To install on a connected device:
./gradlew installDebug- Launch the app. Tap Demo to explore the UI without a car.
- With the K-Pro V4 plugged in via USB-OTG, tap Connect and grant the USB permission prompt.
- Long-press any tile to change its source, unit, label, thresholds, or analog calibration.
- Tap the + tile (or swipe to the next page) to add additional tiles.
