JB4 Mobile is a powerful mobile companion app designed specifically for professionals using the JBTech JB4 system. It enables users to access vehicle data, configure settings, perform diagnostics, and manage maintenance tasks directly from their smartphone or tablet. This tool is perfect for mechanics, fleet managers, and service technicians who work in the field and need quick, reliable access to their diagnostic system on the go.

The key value of JB4 Mobile lies in its convenience and productivity gains. Instead of relying on bulky interfaces, users gain a portable, wireless solution for critical vehicle interactions. From retrieving fault codes during roadside assistance to customizing engine parameters, the app offers immediate access to functionality that was previously tied to physical hardware, streamlining workflows significantly.

App Features

• Wireless Data Transfer: This feature allows users to connect the JB4 system to their mobile device via Bluetooth or Wi-Fi, eliminating the need for physical cables. The benefit is clear: mechanics can instantly view live engine parameters like fuel trim or ignition timing while performing roadside diagnostics, saving valuable time during repairs and improving diagnostic accuracy through real-time monitoring.
• Custom Mapping Management: Create, save, and load custom tuning files directly to the JB4 device. The interface includes visual mapping tools that help users understand how changes affect engine performance, making this feature ideal for enthusiasts modifying their vehicles. This capability provides significant flexibility compared to basic scan tools, allowing precise tuning adjustments without specialized PC hardware.
• Comprehensive Data Logging: The app enables users to record various sensor inputs and performance metrics during driving, then review the logged data later. For fleet managers, this translates to monitoring vehicle health trends over time, while tuners can analyze how modifications affect real-world performance under different conditions, providing actionable insights for optimization.
• Remote System Diagnostics: When the vehicle is connected, users can read and clear fault codes, monitor live sensors, and access system status information remotely. This feature is invaluable for troubleshooting intermittent issues and performing quick checks during pre-trip inspections, ensuring vehicles are road-ready with minimal downtime and no need for specialized PC-based diagnostic systems.
• User-Configurable Dashboards: Customize the app’s interface to show exactly the information you need most—engine temperatures, boost pressure, fuel economy—displayed prominently on your smartphone screen during work. This adaptability ensures the app fits your workflow, whether you’re a tuner monitoring boost curves, a mechanic tracking sensor readings, or a daily driver checking basic vehicle status.
• Multi-Device Support: Connect multiple compatible JB4 units (if applicable) to a single mobile account, simplifying fleet management. For shops with multiple vehicles or enthusiasts with several modified cars, this centralizes system management, reducing the learning curve and allowing seamless switching between different vehicle configurations from one convenient app interface.
