Description
Enhance your BMW G8X M3 or M4 with the WERKE BMW G8X M3 & M4 CS Power Upgrade Genuine BMW Software (DME Only), professionally installed and supported by TUNE+ at Eurowerke. This upgrade applies the official BMW CS engine calibration directly to your vehicle DME, delivering refined factory-engineered performance improvements without altering any other drivetrain or chassis control systems.
Unlike aftermarket remaps or piggyback tuning solutions, this upgrade utilises genuine BMW CS software developed specifically for the G8X M3 & M4 CS platform. The result is sharper performance, improved throttle precision and enhanced drivability while retaining full OEM safety strategies, reliability and seamless system integration.
DME-Only Upgrade - OEM Integration Preserved
This upgrade modifies the engine control unit only, while all other systems remain completely factory-standard:
- TCU - transmission calibration remains OEM
- DSC - Dynamic Stability Control remains unchanged
- VDP - Vehicle Dynamics Processor retains factory calibration
- EPS - Electric Power Steering software remains standard
This approach maintains complete OEM compatibility and preserves the original BMW driving characteristics while benefiting from the improved CS engine calibration.
Real-World Performance Benefits
While peak dyno gains are modest at approximately +19rwkW and +1Nm, the true advantage of the genuine BMW CS software lies in the way the vehicle delivers its power and torque:
- Earlier torque delivery through the rev range
- Stronger and more sustained mid-range performance
- Sharper and more immediate throttle response
- Smoother and more engaging acceleration characteristics
- Improved drivability across all driving modes
These refinements create a noticeably more responsive and dynamic driving experience without sacrificing reliability, refinement or factory operational safeguards.
