bootmod3 N63T2 ECU tuning is a performance calibration developed for BMW vehicles equipped with the twin-turbocharged N63T2 V8 engine. The software recalibrates the factory engine control unit through the vehicle’s OBD interface, optimizing boost pressure, ignition timing and fuel delivery to significantly improve horsepower, torque and overall throttle response while maintaining smooth drivability.

The tuning package includes optimized off-the-shelf performance maps designed for different fuel grades and performance setups. Stage-based calibrations provide substantial improvements in acceleration and power delivery across the entire RPM range depending on fuel type and configuration.

Typical performance gains vary depending on the fuel used. Stage 1 calibrations can deliver approximately 14–19% increases in horsepower and up to around 27% torque gains, while Stage 2 calibrations can achieve up to roughly 24–31% horsepower increases and over 30% torque gains when using higher-octane fuels or ethanol blends such as E30.

Advanced tuning controls allow adjustment of various engine parameters including boost targets, throttle mapping, rev limiter settings, speed limiter removal and exhaust burble configuration. The software also supports custom calibrations for vehicles equipped with upgraded hardware such as larger turbochargers, intercoolers, intake systems or high-flow exhaust components.

Additional capabilities include real-time monitoring and detailed data logging of engine parameters, enabling analysis of vehicle performance and helping optimize tuning setups while maintaining safe engine operation.

bootmod3 N63T3 ECU tuning is a performance calibration designed for BMW vehicles equipped with the twin-turbocharged N63T3 V8 engine. The software recalibrates the factory engine control unit through the vehicle’s OBD interface, optimizing boost pressure, ignition timing and fuel delivery to deliver substantial increases in horsepower, torque and throttle response while maintaining factory drivability.

The tuning package includes optimized off-the-shelf performance maps designed for multiple fuel grades and performance setups. Stage-based calibrations allow the engine to operate with optimized boost and fueling strategies, improving acceleration and power delivery across the entire RPM range depending on fuel type and configuration.

Typical performance improvements vary depending on fuel type. Stage 1 calibrations can provide up to approximately 20–23% increases in horsepower and around 12% torque gains, while Stage 2 calibrations can deliver up to roughly 26–30% horsepower and 18–25% torque improvements when running higher-octane fuel or ethanol blends such as E30 or race fuel.

Advanced tuning features allow extensive control of engine behavior including boost targets, throttle mapping adjustments, rev limiter configuration, speed limiter removal and configurable exhaust burble settings. The system also supports custom calibrations for vehicles equipped with upgraded hardware such as high-flow downpipes, intercoolers, intake systems or turbocharger upgrades.

Integrated monitoring and data logging functions allow users to track numerous engine parameters during operation, enabling detailed performance analysis and further optimization of tuning calibrations.

Power gains of up to 100hp on a stock vehicle without the risks of flashing!

JB4 Features & Benefits

Vehicle Fitment

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.

bootmod3 S55 is an advanced ECU tuning solution developed specifically for BMW vehicles equipped with the S55 engine. The system allows full recalibration of the factory engine control unit (DME) through the vehicle’s OBD port, enabling performance improvements and extensive engine control customization. The tuning platform provides optimized performance calibrations designed to increase horsepower, torque, throttle response and turbo efficiency while maintaining factory drivability.

The tuning package includes access to off-the-shelf performance maps as well as the ability to apply custom calibrations. These maps allow vehicles to run different fuel types and performance configurations depending on hardware modifications and performance goals.

Advanced tuning features allow the driver to switch between multiple calibrations, monitor engine data and adjust performance settings for different driving conditions. The system also supports flex fuel tuning, allowing the engine calibration to automatically adjust to varying ethanol content when equipped with a compatible ethanol sensor.

Additional performance controls include adjustments for exhaust burble, cold start behavior, throttle mapping, boost control, speed limiter settings and other parameters commonly modified during high-performance engine tuning.

bootmod3 B48/B46 ECU tuning is a performance calibration developed for MINI vehicles equipped with the turbocharged B46 and B48 four-cylinder engines. The software recalibrates the factory engine control unit through the vehicle’s OBD interface, optimizing boost pressure, ignition timing and fuel delivery to deliver significant increases in horsepower, torque and throttle response while maintaining smooth drivability.

The tuning package includes a range of optimized off-the-shelf performance maps designed for different fuel grades and hardware configurations. Stage-based calibrations provide noticeable improvements in acceleration and power delivery across the entire RPM range, with gains depending on fuel type and engine compression ratio. High-compression B48 models can achieve up to approximately 54% horsepower and 50% torque increases on Stage 2 calibrations, while low-compression variants also benefit from measurable improvements in both power and torque.

Advanced tuning controls allow modification of various engine parameters including boost targets, throttle sensitivity, exhaust burble configuration, cold-start behavior, rev limiter settings and speed limiter removal. Additional features support flex-fuel calibrations, allowing the engine to adapt to different ethanol fuel blends such as E30, E50 or full E85 when equipped with compatible supporting hardware.

The system also supports custom calibrations for vehicles equipped with upgraded hardware such as larger intercoolers, high-flow downpipes, intake systems or turbocharger upgrades. Extensive engine monitoring and diagnostic data logging allow detailed analysis of engine parameters to assist with performance optimization and safe tuning adjustments.
