Description
Unlock additional performance from your BMW B58 engine with CarBahn Performance 406 HP Stage 1 ECU Software. Developed for select BMW M240i, 340i, 440i, 540i, and 740i applications, this ECU calibration is designed to increase horsepower and torque while delivering a responsive and refined driving experience.
Running on 93-octane fuel, the CarBahn Stage 1 calibration increases calculated flywheel output from the OEM-rated 345 HP / 355 TQ to 406 HP / 388 TQ. Measured wheel output increases from 304 WHP / 312 WTQ to 357 WHP / 342 WTQ.
The calibration also removes the factory top-speed governor, allowing the vehicle to exceed its original electronic speed limitation.
