The Challenge

This blog post is going to be about the advantages of tuning the MAN TGX truck’s Engine Control Unit (ECU). ECU tuning offers significant benefits to your fleet operations by enhancing performance and reliability. By adjusting the settings within the ECU, the engine of your MAN TGX can be optimized, resulting in improved performance.

The MAN TGX, a part of the TG range, was designed to replace the TGA alongside the TGX models. Specifically tailored for long-haul transport, the TGW offers a choice of three different engines. In this blog post, we’ll focus on the MAN TGX equipped with a 12.4L D2676 diesel engine. Through ECU tuning, we can optimize performance, addressing both operational efficiency and known emission system challenges inherent in diesel engines.

The Solution

At Alt Tune, we possess not only the expertise but also the necessary tools to provide the safest and most effective tuning solution. We utilize the Alientech KESS3 system to securely flash the tune onto the MAN TGX. Upon completion, you’ll experience a notable increase in horsepower and torque, enhancing towing capacity and uphill performance. Additionally, optimized engine performance translates to improved driving experience and reduced travel time. Each tune is customized to suit the specific vehicle, driving conditions, and owner preferences, ensuring optimal results.

Reliability is paramount in successfully completing any task. To address emission system issues, we’ve developed a solution integrated into the ECU settings. This solution effectively eliminates emission system challenges, bolstering the reliability of the MAN TGX.

Further Benefits Of ECU Tuning The MAN TGX

Increased Power and Torque

With more power and torque, a tuned truck can handle heavier loads and perform tasks more efficiently. It allows the truck to pull or push larger implements, haul heavier loads, and complete tasks faster, resulting in increased productivity.

Years of Development

We have been tuning the 12.4L D2676 engine for years, and understand how they work as well as the limitation on factory hardware.


Easy and fast programming

Easy, fast and non-evasive via programming the factory-fitted diagnostic port.
