Tuning The Kobelco SK170

2022 Kobelco SK170

Excavator – 5.1L – Transtron ECU

The Challenge

The 2022 Kobelco SK170 is a robust and efficient excavator that stands out for its versatility and performance on construction sites. As one of Kobelco’s top-tier models, the SK170 already delivers impressive power and reliability. However, for construction professionals maximizing capability and productivity is important, and that is where power tuning can offer an exciting opportunity.

In this post, we are looking into how tuning the Kobelco SK170 excavator can bring productivity to your construction site. We are using a 2022 Kobelco SK170 with a Transtron ECU we tuned for a customer as an example. The customer was looking for a way to increase productivity on their construction site and solve the problems that made their SK170 spend unnecessary time in the shop. Here at Alt Tune, we have the tools to minimize downtime for all construction machines.

The Solution

The first step to the solution is to have a look at the SK170. Afterwards, we read the ECU and decided that a power tune and adjusting the emission system using Alientech KESS3 could give the customer what they were looking for. Power tuning for the Kobelco SK170 excavator involves optimizing its engine and performance components to achieve increased horsepower, torque, and overall efficiency.

The emissions system on construction machines is often what causes more time in the shop than what the owner likes. Therefore we adjusted the system to fit the tune so productivity not only was optimized on site but also in minimizing downtime. Power tuning can transform your Kobelco SK170 into an even more powerful and reliable heavy-duty machine, maximizing productivity and making every construction task a breeze.

Further Benefits Of Tuning The Kobelco SK170

Increased Power and Torque

With more power and torque, a tuned machine can handle heavier loads and perform tasks more efficiently. It allows the machine 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 Kobelco’s 5.1L 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.
