For Mercedes C63 AMG enthusiasts seeking to elevate their driving experience, the OBDII JB4 tuner emerges as the premier plug-and-play performance solution. Harnessing technology akin to that utilized in high-performance BMW M models, the JB4 unleashes significant horsepower and torque gains for your AMG C63, all while maintaining the smooth drivability you expect from the factory. Installation and removal are straightforward, typically taking under an hour, making it an accessible upgrade for any owner.
The JB4 distinguishes itself from other Mercedes C63 AMG tuning options with a comprehensive suite of features designed for both performance and safety. This includes sophisticated fuel control to ensure optimal operation at elevated power levels and CANbus integration, enabling the JB4 to monitor and interpret advanced engine data. This deep integration translates to unparalleled performance enhancements and safety measures.
Choose from a range of performance maps tailored to various fuel types, including pump gas, E85 blends, race fuel, and water-methanol injection (WMI). There’s even a valet map for reduced performance when desired. Map selection is conveniently accessible on-the-fly via the optional JB4 mobile app. This app also provides real-time data logging to your smartphone, allows for setting adjustments and custom map modifications, facilitates firmware updates for access to the latest features and maps, and enables reading and clearing of fault codes. Further, you can use it to measure your vehicle’s 0-60 mph times and explore many other functionalities.
For drivers who frequent the track, the JB4 incorporates racing-specific features not commonly found in other systems. User-adjustable boost-by-gear settings offer improved traction from a standstill, optimizing launch performance.
Compatible with both C63 and C63S models, the JB4 is not VIN locked, enhancing its resale value and transferability. Proudly made in the USA, it represents a premium tuning solution for your Mercedes AMG.
To unlock the full potential of the JB4, consider the optional JB4 Mobile connect kit for wireless Bluetooth 4.0 connectivity with iOS and Android devices, or utilize the BMS data cable for Windows laptop connection. Both options provide access to comprehensive data logging and analysis, map adjustments, and firmware updates, ensuring your tuner is always running the latest and most powerful software versions. A separate JB4 Mobile app purchase is required for smartphone connectivity.
Optional Boost Control Module (BCM)
The JB4 connects to the manifold TMAP, charge pipe MAP, and fuel pressure sensors on each engine bank, totaling six connection points, plus OBDII for CANbus integration. These fundamental connections grant the JB4 extensive tuning capabilities. For those targeting extreme boost levels with substantial modifications like upgraded bolt-ons, WMI, larger turbos, or high-octane fuels, the Boost Control Module (BCM) add-on harness can further optimize performance. The BCM, while not currently available, will offer direct wastegate control by connecting to the JB4 harness and the boost control solenoid, enhancing boost management for demanding setups.
