The Challenge

In this article, we will explore how tuning the Freightliner Argosy can enhance its efficiency and help avoid future mechanical expenses. The Freightliner Argosy has more potential than what is offered in its factory-standard configuration.

The Freightliner Argosy is a cabover heavy-duty truck originally designed for highway use in the US and Canada. However, due to a decline in the popularity in these markets, production was shifted to focus on exports. Primarily, the truck has been exported to Australia and New Zealand, where it is recognized for its numerous safety features and comfortable sleeper cabin, making it a perfect choice for long-haul journeys.

The Solution

We use Alietech KESS3 to reprogram Argosy’s Temic DDEC ECU with a customized tune. With a custom tune from Alt Tune, your truck can be adapted to your specific requirements. Whether you wish to navigate steep hills more swiftly or haul heavier loads, we can transform your Argosy into your dream truck. By adjusting various parameters in the ECU, the truck can generate more power and torque, facilitating easier hill climbing and heavier load towing. This not only enhances efficiency but also makes driving more enjoyable.

Emission systems in these trucks can sometimes lead to problems and result in costly mechanical repairs. These issues can be preemptively addressed by incorporating Alt Tune’s emission system solution into the custom tune. This solution aligns the emission settings in the ECU with the customized tune, effectively eliminating potential problems.
