BMW M3 Stage 1 + DCT Calibration

Engine Tune:
Stock 431 hp / 550 Nm
Stage 1 500 hp / 680 Nm
+69 hp / +130 Nm

The F80 M3 is an incredible platform from the factory, but our Stage 1 ECU and DCT gearbox calibration unlock even more from the S55 engine, delivering stronger acceleration, sharper throttle response and improved drivability.

The calibration also reduces the common low-RPM hesitation and “kangarooing” behaviour often experienced during low-speed driving, making the car noticeably smoother in everyday use.

This vehicle was professionally calibrated via AutoTuner OBD using the Bosch MEVD17.2.G ECU, with the original ECU and gearbox software securely backed up prior to programming.

Included:
• Stage 1 ECU performance calibration
• DCT gearbox calibration
• Exhaust flaps open in Sport mode
• Speed limiter removed
• Sports Display recalibrated
• Original ECU and gearbox files securely backed up

Dealer-level diagnostics were completed before and after programming to ensure the vehicle was operating correctly and that no underlying faults were present.
