App Concept

Exhaust Insight Pro

A diagnostic platform for diesel aftertreatment systems that combines OBD-II data, sensor readings (NOx, DEF, temperature), and guided troubleshooting workflows. It helps owners and mechanics quickly identify whether exhaust leaks, sensor faults, or component failures are causing efficiency issues, reducing guesswork and repeat shop visits.

Key Features

Real-time data logging from NOx, DEF, and temperature sensors
Guided diagnostic tree based on fault codes and live data
Historical trend analysis to pinpoint intermittent issues
Remote expert consultation via telemetry sharing

Target Users: Owners and fleet operators of medium-duty diesel trucks (school buses, delivery trucks, etc.) and their mechanics

Revenue Model: $49/month per vehicle for the diagnostic platform; $199 one-time for a telematics dongle
