Mercedes-AMG models are equipped with many electronic limitations from the factory that restrict the full potential of the vehicle. Particularly affected is the CPC (Central Powertrain Controller) , which limits the power, VMAX and torque .
Stefanel Performance offers 100% secure and professional CPC, ECU & TCU optimization – completely remote!
Unlike some suppliers who manipulate load axles and torque values , we work cleanly and gently on the vehicle - without unnecessary interventions that can cause damage.
📌 Why is CPC optimization important?
Many modern Mercedes-AMG models, especially the 4MATIC+ models , have an additional control unit: the CPC (Central Powertrain Controller) . This ensures various factory limitations:
🔴 VMAX limitation: Often limited to 250 km/h as standard, even after chip tuning
🔴 Torque reduction: The CPC regulates the maximum torque and can artificially limit the full power
🔴 Launch Control & Gearbox Locks: The CPC can prevent the vehicle from developing its full acceleration power
🔥 Our CPC optimization removes these limitations without affecting factory security features!
🚀 Which AMG models benefit from CPC & TCU optimization?
Our CPC & transmission optimization is particularly relevant for the following Mercedes-AMG models :
Mercedes-AMG A-Class & CLA:
✅ A35 AMG (W177) / A45 S AMG (W177)
✅ CLA35 AMG (C118) / CLA45 S AMG (C118)
Mercedes-AMG C-Class:
✅ C43 AMG (W205) / C63 S AMG (W205 & W206)
Mercedes-AMG E-Class & CLS:
✅ E53 AMG (W213) / E63 S AMG (W213)
✅ CLS53 AMG (C257) / CLS63 AMG (C257)
Mercedes-AMG SUV models:
✅ GLC43 AMG (X253) / GLC63 S AMG (X253 & X254)
✅ GLE53 AMG (W167) / GLE63 S AMG (W167)
✅ GLS63 AMG (X167)
Mercedes-AMG GT & G-Class:
✅ AMG GT 4-door (X290) – 43, 53, 63 p
✅ G63 AMG (W463A)
These models are all limited in their performance by the CPC as standard – we are removing these limits!
🔧 How does our remote tuning for CPC, ECU & TCU work?
We offer a 100% remote solution , so you don't even have to move your vehicle out of the garage!
✅ 1. You receive an OpenPort 2.0 dongle (e.g. Tactrix) or use your own device
✅ 2. Connection to the laptop via AnyDesk – our expert takes care of the entire process
✅ 3. Read & analyze CPC, ECU & transmission data
✅ 4. Install optimized software for maximum performance
✅ 5. Test the vehicle & enjoy!
👉 Important: A powerful charger such as the GYSFLASH 100.12 is required throughout the process to avoid voltage fluctuations and protect the control units.
