42-signal diagnostic engine with predictive maintenance, fuel coaching, and driver scoring. Software-only — use any BLE adapter.
Lume Scan runs a continuous 42-signal diagnostic engine at 100ms intervals. Not just reading codes — governing your vehicle's health.
Reads 42 OBD-II signals at 100ms intervals across four domains: combustion, fuel system, health & safety, and governance. Continuous monitoring, not just code reading — a real-time governance engine for your vehicle that never sleeps.
Check engine light? Reads the code, translates technician jargon, tells you what's wrong in plain English, and links the exact part.
Detects component degradation 1–3% before it becomes a breakdown. Catches problems weeks before your dashboard does.
Audio coaching through your car speakers. Most drivers save $180–$320/year. Pays for itself in 2 weeks.
42 live gauges updating 10x/second. Driver efficiency scoring, family dashboard, multi-vehicle monitoring. Track your improvement over time with session deltas and historical baselines. Professional-grade telemetry for every driver.
