• Check Engine Light: Diagnose the root cause of that pesky check engine light and avoid unnecessary trips to the mechanic.
• Real-Time Data: Monitor critical engine parameters like coolant temperature, fuel pressure, and exhaust gas recirculation (EGR) valve position.
• Performance Monitoring: Track vital performance metrics like boost pressure, injection timing, and fuel economy.
• Troubleshooting: Quickly identify and resolve issues with sensors, actuators, and other engine components.
