OEM+ CS and CSL Calibration Upgrade for BMW G8x M Cars

Unlock sharper response, tighter control and a more focused driving feel with this factory-derived calibration captured from the celebrated CS and CSL models. Supplied by Evolve and offered by MJ Modifications, this software flash brings the sought-after CS/CSL driving dynamics to your G8x M car with genuine OEM-style refinement.

Why enthusiasts choose this upgrade

• Gearbox mapping: noticeably crisper, quicker upshifts and downshifts in the sportier drive modes for a more connected, performance-focused feel.
• Steering assistance: weightier and more precise electric power steering for improved feedback and confidence through fast road and circuit driving.
• Traction strategy: a more permissive MDM window that allows additional slip before intervention for better traction tuning and enhanced drift characteristics.

We have installed this calibration on customer cars and the feedback has been outstanding. Drivers report a meaningful step up in engagement, control and enjoyment without compromising day-to-day usability.
