Description
Unlock increased performance from your BMW with CarBahn Performance 707 HP Stage 1 ECU Software, engineered for select BMW 750i xDrive, M550i, and M850i models from 2021 through 2025. This performance ECU calibration is designed for automatic transmission applications and supports xDrive and RWD configurations.
On 93-octane fuel, the Stage 1 software increases calculated flywheel output to 707 HP and 711 lb-ft of torque, while measured wheel output reaches 580 WHP and 583 lb-ft of wheel torque. Compared with the stock calibration, this represents gains of up to 137 flywheel HP and 58 lb-ft of flywheel torque, or 112 wheel HP and 47 lb-ft of wheel torque.
CarBahn EVO Intelligent software adapts seamlessly to various fuel octane levels, optimizing performance without compromising safety. It retains existing safety features while adding extra protection where necessary.
The software also removes the factory top-speed governor and offers an optional exhaust overrun feature for enhanced burble sounds.
