Unlock the full performance potential of your 2021+ Maserati MC20 3.0L Nettuno Twin-Turbo V6 with the Burger Motorsports (BMS) JB4 Performance Tuner. Designed specifically for Maserati's advanced Nettuno engine platform, the JB4 is a sophisticated plug-and-play tuning solution that works alongside the factory ECU to optimize boost pressure, ignition timing, and fueling for increased performance and improved turbo response.

The JB4 transforms the driving experience of the MC20 by delivering stronger acceleration, reduced turbo lag, and enhanced throttle response while maintaining factory drivability. With included maps supporting pump gas, race fuel, and ethanol blends up to 30% E85, the JB4 allows owners to customize performance based on fuel availability and vehicle modifications.

Unlike basic performance chips, the JB4 uses advanced CANbus integration and real-time engine monitoring to optimize power delivery while maintaining important factory safety strategies. The system continuously monitors critical engine parameters and adjusts performance settings accordingly, providing a smooth and reliable upgrade suitable for both street and performance driving.

Installation is completely plug-and-play and connects to easily accessible engine bay sensors. The discreet design allows the JB4 to be installed or removed quickly without permanent modifications or visible traces. Fuel economy remains unchanged during normal driving, and the system is compatible with all factory driving modes.

Included with every JB4 is the JB4PRO App, providing wireless control through compatible iOS and Android devices. Monitor vehicle data, switch performance maps, record and analyze logs, update firmware, and access advanced diagnostic tools directly from your smartphone.

Designed and assembled in the USA, the JB4 includes a durable billet aluminum enclosure and is backed by a 5-year warranty.

Note: This product is currently in BETA development. Performance maps and features may continue to improve through future firmware updates.

What Is a JB4?

The JB4 is a plug-and-play performance tuner designed for turbocharged vehicles. It installs between the vehicle's engine sensors and ECU, allowing it to modify performance parameters without permanently altering factory ECU software.

Through advanced CANbus communication, fuel and spark control, Bluetooth connectivity, and real-time data monitoring, the JB4 delivers performance improvements comparable to ECU tuning while preserving factory safety systems.

Unlike VIN-locked ECU flashes, the JB4 can be quickly removed, transferred between compatible vehicles, or resold. Burger Motorsports continues to release firmware updates and improved performance maps, allowing the system to evolve with future development.

Is the JB4 a Real Tune?

Yes. The JB4 is a true performance tuning system. By accessing real-time vehicle data through engine sensors and CANbus communication, the JB4 can adjust boost pressure, ignition timing, air/fuel ratios, and fuel trims to increase power and torque.

The result is a smooth, reliable performance upgrade that maintains factory safety protections without requiring ECU unlocking, flashing, or permanent software changes.
