Description
CarBahn Performance Stage 2 ECU Software Power Package is engineered for BMW G8X M2, M3, and M4 models equipped with the S58 engine and manual transmission. This package combines CarBahn Stage 2 software with a heat exchanger and CarBahn HP air filters to increase horsepower and torque while maintaining the vehicle's existing safety systems.
On 93-octane fuel, the package produces up to 701 flywheel horsepower and 623 lb-ft of flywheel torque, with measured output reaching 617 wheel horsepower and 549 lb-ft of wheel torque.
With 100-octane fuel, the tuned calibration produces up to 715 flywheel horsepower and 632 lb-ft of flywheel torque, with measured output reaching 630 wheel horsepower and 557 lb-ft of wheel torque.
CarBahn EVO Intelligent software seamlessly adapts to various fuel octane levels, optimizing performance without compromising safety. It retains existing safety features while adding extra protection as needed.
The package also removes the factory top-speed governor.
The software was developed with the CarBahn heat exchanger installed to achieve the claimed power output. The heat exchanger is required for the matching factory warranty.
Important: This package can ONLY be installed at an Authorized CarBahn dealer and fits manual transmission-equipped models only.
