Short answer: In Mercedes-AMG vehicles, the 250 km/h VMAX limiter is located not only in the engine control unit (ECU), but also in the Central Powertrain Controller (CPC). A pure ECU adjustment is simply overridden by the CPC. Proper VMAX removal eliminates the limit in both control units – without load axis manipulation or faked torque values that would damage the transmission.
Mercedes-AMG vehicles are known for their high performance – but many models are electronically limited to a top speed of 250 km/h as standard. Some models with the AMG Driver's Package or S-variants have a slightly increased VMAX, but the full potential remains untapped. 🚀
The limitation is stored not only in the engine control unit (ECU) but also in the Central Powertrain Controller (CPC). Therefore, a pure ECU adjustment is often not sufficient – for a complete release, the CPC must also be optimized.
⚙️ Why is VMAX limited ex works?
The factory limitation is due to several reasons:
- 🔹 Protection against excessive strain on tires & brakes
- 🔹 Compliance with legal requirements & insurance guidelines
- 🔹 Limitation by CPC to enforce torque and VMAX limits
Even if the engine control unit can provide higher performance, the top speed remains limited by the CPC. Therefore, a complete release of the VMAX is only possible through an optimized calibration of all relevant control units.
🔥 How does VMAX removal work?
In Mercedes-AMG vehicles, several control units are involved in the limitation. A clean VMAX removal therefore includes:
🚀 Adjustment of the CPC (Central Powertrain Controller)
- ✔ Removal of the factory torque and VMAX limit
- ✔ No limitation by load axis manipulation
⚙️ Optimization of the ECU (Engine Control Unit)
- ✔ Adjustment of maps for top speed
- ✔ Ensuring that the ECU takes over the VMAX release
🔥 Calibration of the TCU (Transmission Control Unit)
- ✔ Optimization of shifting strategies for higher speeds
- ✔ Adjustment of transmission torque releases
✅ Which AMG models benefit from VMAX removal?
Our solution is available for all current AMG models with VMAX limitation, including:
- ✔ A 45 AMG (W177) – standard limited to 250 km/h
- ✔ C 63 AMG (W205/W206) – CPC-based limit
- ✔ E 63 AMG (W213) – VMAX restriction via CPC & TCU
- ✔ GLC 63 AMG (X253/C253) – full unlock possible
- ✔ GT 63 S AMG (X290) – electronic limit adjustable to 315 km/h
