M133 ECU Tune / CLA45 AMG / GLA45
This ECU calibration is engineered specifically for the 2014–2019 M133 AMG platform and built to outperform typical off-the-shelf maps. Expect sharper response, stronger mid-range torque, and far more consistency in real driving conditions.
Typical Gains: +70 hp and +180 lb-ft depending on hardware, fuel, and climate.
Vehicle Compatibility
| Model | Engine | Years |
|---|---|---|
| CLA45 AMG | M133 2.0L Turbo | 2014–2020 |
| GLA45 AMG | M133 2.0L Turbo | 2015–2020 |
What You’ll Feel Immediately
- Harder mid-range punch that pulls well beyond 5,000 rpm.
- Sharper throttle response with no flat spots or delay.
- More stable boost with improved wastegate & DV control.
- Cleaner shifts with correct torque modeling (TCU stays happy).
- Higher repeatability even in warmer climates or back-to-back runs.
Why This Tune Makes More Power
Power on the M133 comes from improving efficiency — not pushing unsafe timing. This calibration is built around how the M133 actually behaves under real load, temperature, and airflow conditions.
- Boost control optimized to eliminate early tapering.
- Safer ignition strategy matched to real fuel quality.
- Improved load targeting for stronger sustained torque.
- DV & wastegate calibration for stable boost at higher airflow.
- OEM safeguards preserved — nothing dangerous turned off.
- Optional boost curve shaping (low, mid, or high RPM bias depending on hardware).
Recommended Supporting Mods
Frees up exhaust flow and reduces backpressure for faster spool and improved top-end power.
Reduces under-hood heat, improves spool consistency, and protects nearby components on the M133 turbocharger.
Prevents boost bleed, stabilizes pressure, and improves throttle response under load.
Dramatically lowers charge temps and improves repeatability during back-to-back acceleration.
Improves airflow for enhanced throttle response, horsepower, and engine efficiency.
