About this app

HonDash for Android turns your Android device into a real-time digital instrument cluster for Honda engines running a Hondata K-Pro V4 ECU.
Mount your phone or tablet in the car, connect via USB-OTG, and get a fully customizable dashboard at your fingertips.
━━━ FEATURES ━━━
🔧 LIVE ECU DATA
Real-time polling from your Hondata K-Pro V4 over USB-OTG. See what your engine is doing, as it happens.
📊 CONFIGURABLE TILE DASHBOARD
• 2×2 grid layout with multiple pages
• Long-press any tile to configure it
• Tap "+" to add more tiles
• Swipe between pages
📡 WIDE SENSOR SUPPORT
RPM, ECT, IAT, TPS, MAP, AFR, battery voltage, vehicle speed, gear position, and 8 generic analog inputs (AN0–AN7).
⚙️ FULL CUSTOMIZATION
• Per-tile unit selection (°C/°F, psi/bar, km/h/mph)
• Custom label override for any tile
• Per-tile warning and alarm thresholds with hard-flashing alerts
• Per-analog-channel linear calibration (e.g. 0.5–4.5V → 0–100 psi)
🎮 DEMO MODE
Explore the full UI without any hardware. A synthetic ECU drives every tile so you can set up your layout before getting in the car.

Your layout, thresholds, and calibration are saved automatically and restored on every launch.
