Our ECU Remap – M177 4.0L Twin-Turbo V8

Our custom ECU remap for the W222 S63 M177 is developed in-house, calibrated specifically for Australian fuel quality, local conditions, and how the vehicle is actually used. We do not use generic or offshore files.

What our S63 ECU remap delivers:

• Strong gains in power and torque, especially through the mid-range

• Sharper, more linear throttle response

• Optimised boost control and torque modelling

• Smoother part-throttle and highway drivability

• Retention of all factory safety strategies and safeguards

The result is an S63 that feels lighter, more responsive, and more authoritative, without compromising comfort, refinement, or reliability.

TCU Remap – AMG SPEEDSHIFT MCT 9-Speed

The factory transmission calibration in the W222 S63 prioritises smoothness and drivetrain protection, which can feel soft once additional torque is unlocked. Our TCU remap is designed to work in harmony with the ECU calibration.

TCU tuning benefits:

• Faster, cleaner shift execution

• Improved torque handling logic

• Reduced hesitation during kick-down

• Sharper response in Sport and Manual modes

• Improved overall control and drivability

This upgrade transforms how the S63 delivers power — making it feel decisive and composed, rather than delayed.

Exhaust Upgrades (Optional)

While the M177 already delivers an impressive AMG soundtrack, much of its character is muted from factory. We offer select exhaust upgrade solutions that enhance sound and flow without introducing drone or harshness.

Our approach:

• Quality cat-back exhaust systems

• Valve-controlled options where applicable

• Improved exhaust flow to support tuning

• Refined AMG tone — not excessive noise

Exhaust upgrades complement our ECU remap exceptionally well but are not required to achieve excellent results.
