Description
Unlock more performance from your BMW B58-powered vehicle with CarBahn Performance 477 HP Stage 1 ECU Software. Designed for select 2021–2024 BMW M240i, M340i, M440i, and Z4 M40i models with automatic transmissions, this Stage 1 ECU calibration delivers increased horsepower and torque while maintaining the factory vehicle's safety systems and drivability.
On 93-octane fuel, the CarBahn Stage 1 calibration increases output from a stock 420 HP / 463 lb-ft of torque at the flywheel to an impressive 477 HP / 516 lb-ft of torque. Measured wheel output increases from 345 WHP / 380 lb-ft WTQ to 391 WHP / 423 lb-ft WTQ.
The calibration also removes the factory top-speed governor. CarBahn's EVO Intelligent software is designed to adapt seamlessly to different fuel octane levels, optimizing performance while maintaining appropriate safety strategies.
