JB4 Performance Tuner for Mercedes-Benz C63, E63, GTS, GLC, Including S models
SKU: MB C63 JB4
Power gains of up to +100whp and +100wtq to your AMG
The JB4 is simply the most powerful and feature-rich tuning system available for your AMG. Using the same technology as our advanced tuning systems for the BMW M3 and M5 models, our new AMG C63 system delivers factory smooth performance increases in a package that can be installed or removed in under an hour. The JB4 includes many features not found on other competitive AMG tuning products including:
Fuel control to ensure safe operation at higher power levels. CANbus allowing the JB4 to monitor and integrated advanced engine data for unparalleled perforation and safety. Performance maps for pump fuels, E85 mixtures, race fuels, WMI, and even a lower than stock performance VALET map, all selectable on the fly via the optional JB4 mobile phone app. With JB4 Mobile you can also datalog to your phone, enter setting or custom map changes, update the firmware to unlock new features and maps as we add them, read or delete fault codes, measure your 0-60 time, and much more.
In addition, the JB4 includes many useful racing features not found on any other system including user-adjustable boost by gear to improve traction off the line.
The JB4 is compatible with both C63 and C63S models and is not VIN locked so it can be moved to your next vehicle or resold, and is made in the USA.
Wirelessly connect the JB4 to your Bluetooth 4.0 compatible iOS and Android device via the JB4 Mobile connect kit, or to your Windows laptop with the BMS data cable. Both options allow you to record and analyze vehicle and tuning data, change JB4 performance maps, and update JB4 firmware as we release free newer versions with updates, more powerful maps, and new features under development. Separate JB4 Mobile app purchase also required.
Optional BCM (Boost Control Module)
The JB4 attaches to the manifold TMAP, chargepipe MAP, and fuel pressure connections on each side of the engine, for six total connection points plus OBDII for CANbus. These fundamental attachments provide the JB4 with a wide range of tuning adjustments. For vehicles targeting very high boost levels using heavy bolt modifications, WMI, larger turbos, and/or very high octane, additional wastegate dutycycle may be beneficial in driving boost up to the higher target. To increase wastegate dutycycle the BCM add on harness is required. Although not currently available it will be $199 and plugs into the JB4 harness and the boost control solenoid under the vehicle for direct wastegate control.

What is a JB4?
The JB4 is a plug & play tune available for turbocharged vehicles. The JB4 tuner installs between your car's sensors and its DME/ECU (computer) and manipulates vehicle performance through these connections making your vehicle much faster. While it's not the only tuning system that operates this way the JB4 separates itself from the competition with much more advanced connection points and processing including CANbus, fuel & spark control, Bluetooth to your smartphone, and a variety of innovative and advanced features not possible with any other system. BMS regularly publishes free mapping and firmware updates adding performance and features as ongoing development allows. In addition, the JB4 system is not VIN-locked to your vehicle and can quickly be removed and swapped between cars or resold at a later time. Often imitated but never duplicated the JB4 has been the gold standard in plug and play turbocharged performance tuning for over a decade.
