TCU Tune

This TCU tune results in significantly quicker and firmer gear shifts, whether you are accelerating or downshifting. The improved shifting is not only about speed and feel; it also allows for greater torque capacity. This increased torque capacity is particularly beneficial for modified vehicles that produce substantially more power than their stock configuration. By enhancing the transmission's ability to handle higher torque loads, the Weistec TCU Tune contributes to improved reliability and performance under demanding conditions. Key features include faster shifting, firmer shifting, improved street and track performance, and increased torque capacity, along with increased software torque limits. Installation of this TCU tune involves a reflash of your original ECU. The process requires sending your original ECU to Weistec. The company provides detailed instructions on how to get your ECU/TCU tuned through their website. Please note the California Proposition 65 warning regarding cancer and reproductive harm. This TCU tune is compatible with various Mercedes-Benz AMG GT models equipped with the M178 4.0TT engine, including the GT, GT C, GT R, GT R Pro, and GT S variants, with model years often starting from 2015 onwards.
