Description

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.
