Mercedes-AMG CLA45 & GLA45 ECU Tune – M133 2.0L Turbo Performance Calibration
Mercedes-AMG CLA45 & GLA45 ECU Tune – M133 2.0L Turbo Performance Calibration
Couldn't load pickup availability
This ECU calibration is developed specifically for the Mercedes-AMG M133 2.0L turbo platform. It is engineered to outperform typical off-the-shelf maps by improving response, mid-range torque, and consistency under real driving conditions.
Typical Gains: +70 hp and +180 lb-ft depending on hardware, fuel quality, and operating conditions.
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 strongly well past 5,000 rpm.
- Sharper throttle response without flat spots or hesitation.
- More consistent boost behavior through refined load and torque control.
- Cleaner shifts through proper torque modeling that keeps the TCU satisfied.
- High repeatability during back-to-back pulls or in warmer conditions.
Why This Tune Makes More Power
- Boost and load targets optimized to minimize early tapering.
- Ignition strategy calibrated for realistic fuel quality.
- Improved torque targeting for stronger sustained acceleration.
- Wastegate and DV logic refined within the limits of the factory hardware.
- OEM safeguards preserved to maintain reliability.
- Optional boost curve shaping based on hardware and driving goals.
Recommended Supporting Mods
Significantly reduces exhaust backpressure after the turbocharger. This improves turbine efficiency, allowing the engine to make more power and hold torque more consistently at higher RPM. Removes factory catalytic converter.
Prevents heat from radiating into the engine bay. This reduces heat soak and helps maintain more consistent performance during repeated or sustained driving.
Helps maintain boost pressure during acceleration, throttle transitions, and between shifts for more consistent power delivery.
A larger dual-pass intercooler lowers charge temps, allowing the ECU to maintain power more consistently during hard driving.
Improves overall thermal control by increasing heat dissipation at the front of the vehicle. This helps prevent power reduction caused by rising temperatures during sustained driving.
Adds cooling capacity to help manage engine and system temperatures under load. Reduces heat soak and keeps performance more stable in warm conditions or aggressive use.
Reduces restriction ahead of the turbocharger, allowing the engine to breathe more freely. Improves throttle response and supports higher airflow when combined with tuning.
Larger-diameter intake designed to support increased airflow at higher boost levels. Best suited for tuned vehicles running upgraded exhaust and cooling components.
Increases intake volume and reduces restriction at the factory air box. Supports smoother airflow and better consistency on tuned setups.
