Description
BMW G42 M240i Stage 1 Remap Package. The BMW G42 M240i, powered by the legendary B58 3.0-litre inline-six, is widely regarded as one of the most capable tuning platforms in the modern era. While the factory output of 374bhp and 369lb-ft is impressive, it represents only a fraction of the B58’s true potential.
Our M240i Stage 1 G-Series Remap is engineered to unlock this untapped performance, transforming your refined coupe into a powerhouse capable of challenging—and outperforming—established super-saloons.
We do not believe in “one-size-fits-all” tuning. Every M240i Stage 1 Calibration is developed and validated through rigorous dyno testing and real-world data logging. This bespoke approach ensures:
-
Linear Power Delivery: Smooth, relentless acceleration without the “peakiness” of generic files.
-
B58 Thermal Management: We keep all factory engine protection systems active to ensure long-term reliability.
-
Drive Mode Integration: Maintaining the refined “Grand Tourer” feel in Comfort mode, with a sharpened, aggressive response in Sport+.
Expected M240i Stage 1 remapped performance figures:
Power: 450-460 bhp
Torque: 470-480 lb/ft
