This software can be applied to any G8X M3/M4 and the software coded into the following ECU’s:
CSL/CS Transmission Flash – Responsive gear changes and a refined feel in Sport and Sport+ modes.
The update also enhances exhaust burble characteristics, delivering the distinctive acoustic signature of the CS/CSL, ensuring every drive feels track-inspired and performance-focused.
CSL/CS Electronic Power Steering – Stiffened feel to steering for improved control and handling with more advanced power assist.
CSL/CS Traction Control – More slip in MDM before power is cut/reduced and allows improved traction control setting and drift characteristics.
Bring your G8X M3 or M4 to CS-level precision with our G8X CS Chassis Flash—a direct software adaptation from the factory BMW M3 CS and M4 CS. This flash optimizes your car’s suspension, steering, and differential calibration for sharper response, improved composure, and increased confidence in dynamic driving situations.
Whether you’re carving back roads or pushing hard on track, the CS chassis software gives your G8X the poised, agile feel of BMW’s most refined M offering—without any hardware changes.
