Excavator and dozer tuning for Albury-Wodonga contractors

Why contractors look at tuning

Excavators, dozers and graders spend long days under load, often on tight schedules. Every hour a machine is off the job costs you money, so most contractors want a tune that is built around how the machine actually works, not a generic file pulled off the internet.

A custom ECU tune adjusts how the engine is mapped for your machine and your work. Results depend on the engine, the machine and how it is used, so we talk through what is realistic before anything changes.

Machines we work on

We work on heavy machinery across Albury, Wodonga, Wagga Wagga, the Riverina and northern Victoria, including:

• Excavators such as the Cat 336
• Dozers such as the Komatsu range
• Graders such as the John Deere
• Scrapers and articulated dump trucks

Every engine and every site is different, so we look at your specific machine first.

AdBlue and DPF issues on off-road equipment

Modern off-road and construction equipment often has AdBlue and DPF systems that can cause downtime on site. We can help with these systems on off-road and construction equipment. We do not do this work on on-road trucks.

What to ask before you book

• What will actually change on my machine and why?
• How does it affect my manufacturer warranty?
• Can the work be done on site so the machine stays on the job?
• What is the price, confirmed before work starts?

Warranty is a fair question. The answer depends on your machine, its age and the manufacturer's terms, and we are upfront about what the work involves so you can make an informed call.
