Mining and earthmoving equipment runs hard. An excavator working a full shift burns 20 to 35 litres of diesel per hour. A large dump truck hauling material across a mine site can consume 40 to 60 litres per hour. Multiply that by the number of machines in your fleet, across thousands of operating hours per year, and diesel becomes one of the single largest cost centres in the operation.
ECU remapping won't halve your fuel bill. But a well-calibrated remap on heavy machinery consistently delivers fuel savings of 8 to 18%, depending on the machine, application, and operating pattern. At that scale, the savings are material and ongoing.
Why Does ECU Remapping Reduce Fuel Consumption?
The counterintuitive part: you might expect that more power means more fuel. In practice, a remapped machine is often more fuel-efficient because it's doing the same work with less effort.
Here's the mechanism. A factory-tuned engine has to work harder to produce a given amount of torque, because the torque curve has been flattened and limited. When that machine hits a load — an excavator breaking ground, a dozer pushing a heavy cut — the engine has to downshift, lug harder, and push more fuel through a longer work cycle.
After remapping, the torque is available lower in the rev range. The machine gets through the same load with less engine stress, fewer gear changes, and a shorter cycle time. The fuel burned per tonne of material moved, or per hour of productive work, goes down.
More torque at lower RPM = less time at high load = less fuel consumed per unit of work. The maths works in your favour.
Estimated Annual Fuel Savings by Machine Type
Based on typical operating hours and consumption rates for Queensland mining and earthmoving operations:
| Machine Type | L/hr (avg) | Annual Hours | Fuel Cost/yr | Saving (15%) |
|---|---|---|---|---|
| Mid excavator (20t) | 18 L/hr | 2,000 hrs | $64,800 | ~$9,700 |
| Large excavator (40t+) | 30 L/hr | 2,000 hrs | $108,000 | ~$16,200 |
| Dozer (D8 class) | 25 L/hr | 2,000 hrs | $90,000 | ~$13,500 |
| Articulated dump truck | 22 L/hr | 2,000 hrs | $79,200 | ~$11,900 |
Based on diesel at $1.80/L. Actual savings vary by machine and application.
A single large excavator saving $16,000 per year in fuel more than recovers the cost of a tune in the first season. A fleet of five machines generates savings well into six figures annually.
Which Mining Machines Can Be Tuned?
LP Tuning works with the full range of earthmoving and mining equipment used in Queensland operations:
- Excavators: Komatsu, Hitachi, Cat, Volvo, Kobelco, Liebherr, Hyundai
- Dozers and graders: Komatsu D Series, Cat D Series, Volvo graders
- Articulated dump trucks: Komatsu HM Series, Volvo A Series, Bell B Series
- Rigid dump trucks: Komatsu HD Series, Cat 773/777
- Wheel loaders: Cat 966/972/980, Komatsu WA, Volvo L Series
- Skid steers, telehandlers, and compact equipment
We've tuned Komatsu HM400 articulated dumpers and seen power gains of over 70hp alongside meaningful fuel savings — the kind of result that shifts the economics of running heavy iron.
On-Site Service: No Downtime Beyond the Appointment
LP Tuning is a mobile service. We come to your site in Queensland — mine, quarry, construction project, or equipment depot. The tune is applied on-site, and your machine is back working the same day. No transport, no dealer wait times, no unnecessary downtime.
We carry our own equipment and are set up for remote site access where required. If you're managing a fleet, we can work through multiple machines on a single site visit.
Tell Us Your Fleet. We'll Run the Numbers.
Send us your machine makes, models, and annual operating hours and we'll give you a realistic estimate of what tuning could save you — before you spend a dollar.

Yes — with one important condition. The tune must be applied correctly, by a calibrator who understands heavy machinery and uses validated software maps for your specific engine variant.
LP Tuning uses software backed by AgroEcoPower, with real-world data from 350,000+ installations. Every tune is applied within the manufacturer's mechanical limits. We do not push engines beyond what they were engineered to handle. The goal is optimisation, not overload.
We also offer a 30-day trial on all work. If the performance isn't what you were expecting, we reverse the tune at no cost.
