Unlock the full performance potential of your 2020+ Mercedes-Benz A220 or A250 with the GCA Performance ECU Tune. Designed by German Car Accessories (GCA) under our performance division, this custom ECU calibration enhances your vehicle’s throttle response, acceleration, and overall driving experience.
Engineered specifically for the W177 A-Class 2.0L Turbocharged M260 engine, this tune optimizes engine parameters to deliver stronger torque, improved responsiveness, and a more engaging power delivery throughout the RPM range. Whether you're commuting daily or looking for a sharper driving experience, the GCA Performance ECU Tune helps your Mercedes perform beyond factory limitations.
GCA Performance securely saves your original ECU data, allowing you to restore your vehicle back to factory settings at any time. Each calibration is optimized according to your vehicle configuration and fuel quality for improved performance and drivability.
For vehicles equipped with upgraded downpipes, Stage 2 tuning is available with GCA Performance Downpipes. Stage 2 calibration is included at no additional charge. Downpipe readiness and check engine light suppression are available for off-road applications only.
The A220/A250 comes equipped with factory torque and horsepower limitations. To maximize available performance, a CPC module upgrade is recommended. Vehicles manufactured after June 2020 may require an ECU unlock before tuning can be completed.
