Retuning the factory ECU is a popular way to increase power and fuel efficiency in heavy-duty vehicles like tractors. In this post, we’ll take a look at how retuning the factory ECU can improve the performance of a John Deere tractor using a Power Tune tuning method and a Alientech KESS2 tool.


The John Deere Harvester S670 is a versatile machine. John Deere also makes a wide range of machines for different applications, from farming and construction to logging. However, like all vehicles, it can benefit from a little extra power and fuel efficiency.

One of the best ways to achieve these improvements is through retuning the factory ECU. This process involves reading the tractor’s factory engine control unit (ECU) to gather information about its current performance settings using Alientech KESS2. This information is then used to create a custom tune that can be loaded onto the ECU to improve the tractor’s performance using Power Tune tuning method.
The type of tune that is created will depend on the specific make, model, year, and type of tractor, as well as the transmission, engine, and fuel type.

Once the custom tune has been created, it can be loaded onto the tractor’s ECU using a specialized tool, such as an Alientech KESS2. This process is usually quick and easy.

The result of retuning the factory ECU is often a noticeable increase in power and fuel efficiency. This can be especially beneficial for tractors that are used for heavy-duty applications, such as plowing, tilling, and hauling heavy loads. It can also help to reduce the overall cost of operating the tractor, by reducing fuel consumption and maintenance costs.


If you’re a tractor owner in Australia and looking for ways to improve your vehicle’s performance, retuning the factory ECU is definitely worth considering. With the right Power Tune tune, loaded using Alientech KESS2 tool, you can enjoy increased power and fuel efficiency, as well as lower operating costs.
