M177 ECU / TCU / CPC Tuning
The M177 platform is one of AMG’s most advanced and capable engines, but from the factory it is heavily restricted by conservative software limits designed for emissions, drivetrain protection, and global fuel quality.
DTK Motorsport develops custom calibration solutions for the ECU, TCU, and CPC, unlocking the true performance potential of the M177 while maintaining OEM-level drivability and long-term reliability.
Every vehicle is tuned from scratch based on its exact configuration — no generic or off-the-shelf files are ever used.

ECU Tune (Engine Control Unit)
The ECU tune is the foundation of performance on the M177 platform. Our calibrations safely optimize boost control, ignition timing, fueling, and torque modeling to deliver substantial power gains without compromising reliability.
Key Benefits:
•Significant horsepower and torque gains
•Improved throttle response and drivability
•Optimized boost control across the powerband
•Removal of factory speed limiter (where applicable)
•Calibrated for stock or modified hardware
Power Gains:
•Stock hardware: typically +120–150 HP / +150–200 lb-ft
•Gains increase further with downpipes, intakes, and higher-octane fuel
Tunes are optimized for 91, 93, and race fuel or ethanol blends depending on customer preference and local availability.
⸻
TCU Tune (Transmission Control Unit)
The factory transmission calibration limits the true potential of the M177 drivetrain. Our TCU tune completely transforms how the car drives — both in daily use and under full load.
Key Features:
•Faster and firmer gear changes
•Increased clutch pressure to eliminate slip
•Recalibrated torque limits for higher power output
•Optimized shift logic in all drive modes
•Improved launch behavior and consistency
The result is a transmission that feels sharper, more direct, and fully capable of handling increased engine output.
⸻
CPC Tune (Central Powertrain Controller)
The CPC acts as the gatekeeper of torque on modern AMG platforms. Even with an ECU tune, the CPC can aggressively limit power if left untouched.
Our CPC calibration:
•Removes hidden torque caps
•Ensures ECU and TCU work together seamlessly
•Allows full utilization of engine and transmission tuning
•Improves overall power delivery and consistency
For higher-power setups, CPC tuning is mandatory to achieve the expected results safely and reliably.

Custom Calibration Philosophy
At DTK Motorsport, we do not sell pre-made files. Every M177 calibration is built specifically for:
•Vehicle model and year
•Hardware configuration
•Fuel quality
•Intended use (street, roll racing, track)
This approach ensures:
•OEM-like cold starts and drivability
•Smooth power delivery
•Maximum performance within safe limits
⸻
Remote Tuning & Support
We offer worldwide remote tuning with full support.
Included with every tune:
•Required tuning interface (where applicable)
•Custom calibration files
•Data logging review
•Free lifetime retunes for hardware upgrades
Dyno tuning can also be arranged locally with real-time remote support for maximum optimization.
