Short Answer: We optimize your Mercedes-AMG's ECU, CPC, and TCU completely remotely using the Tactrix OpenPort 2.0 interface – no workshop appointment needed, available worldwide. Unlike providers who manipulate load axes or nut torque values, we work with clean, OEM-compliant calibrations: VMAX removal, full torque release, optimized launch control – without interfering with factory safety features.
Mercedes-AMG models come from the factory with many electronic limitations that restrict the vehicle's full potential. Particularly affected is the CPC (Central Powertrain Controller), which limits power, VMAX, and torque.
Stefanel Performance offers 100% safe and professional CPC, ECU & TCU optimization – completely remote!
Unlike some providers who manipulate load axes and torque values, we work cleanly and car-friendly – 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 provides various factory limitations:
🔴 VMAX limitation: Often limited to 250 km/h as standard, even after chip tuning
🔴 Torque reduction: The CPC regulates maximum torque and can artificially restrict full power
🔴 Launch Control & transmission locks: From the factory, the CPC can prevent the vehicle from unleashing its full acceleration performance
🔥 Our CPC optimization removes these restrictions without affecting the factory safety functions!
🚀 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 S
✅ G63 AMG (W463A)
All these models are limited in their performance by the CPC as standard – we remove 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 from the garage!
✅ 1. You receive an OpenPort 2.0 dongle (e.g., Tactrix) or use your own device
✅ 2. Connect to a laptop via AnyDesk – our expert handles the entire process
✅ 3. Read out & analyze CPC, ECU & transmission data
✅ 4. Upload optimized software for maximum power & performance
✅ 5. Test and enjoy your vehicle!
👉 Important: Throughout the entire process, a strong charger like the GYSFLASH 100.12 is required to avoid voltage fluctuations and protect the control units.
