bootmod3 N13 ECU tuning is a performance calibration designed for BMW vehicles equipped with the turbocharged N13 four-cylinder engine. The software recalibrates the factory engine control unit through the vehicle’s OBD interface, optimizing boost pressure, ignition timing and fuel delivery to increase 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 hardware configurations. These calibrations improve engine output and acceleration across the entire RPM range while maintaining factory safety systems and engine protections.

Stage-based calibrations provide noticeable gains in engine performance depending on fuel type and vehicle configuration. Stage 1 and Stage 2 maps are available, including aggressive exhaust burble variants, allowing drivers to select different performance profiles suited to their driving style and vehicle modifications.

Advanced tuning controls allow adjustment of various engine parameters including boost targets, throttle mapping, rev limiter configuration, speed limiter removal and exhaust burble settings. The system also supports custom performance calibrations for vehicles equipped with upgraded hardware such as larger intercoolers, intake systems, downpipes or turbocharger upgrades.

Integrated data logging and engine monitoring functions allow users to analyze numerous engine parameters during operation, helping optimize tuning setups and maintain safe engine performance.

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 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.

bootmod3 B58 ECU tuning is a performance calibration designed for vehicles equipped with the turbocharged BMW-derived B58 engine used in the Toyota Supra A90 and A91. The software enables complete recalibration of the factory engine control unit (DME) through the vehicle’s OBD interface, allowing significant improvements in horsepower, torque and overall engine responsiveness.

The tuning package includes optimized performance maps developed for different fuel types and hardware configurations. These calibrations adjust boost pressure, ignition timing and fuel delivery to maximize engine efficiency and performance while maintaining smooth drivability across the entire RPM range.

Advanced tuning functions provide extensive control over engine behavior and performance parameters. These include adjustable exhaust burble settings, cold-start behavior, top speed limiter removal, throttle mapping adjustments, boost-by-gear control and configurable exhaust valve operation.

Additional features support flex-fuel operation when paired with a compatible ethanol sensor, allowing the engine calibration to automatically adapt to varying ethanol blends such as pump fuel, E30, E50 or full E85. The tuning system also supports data logging and monitoring of numerous engine parameters to assist with performance optimization and diagnostics.
