Diesel ECU Remapping, Diagnostics & Upgrades

Modern diesel vehicles are controlled by a complex network of sensors and software. ECU remapping (engine control unit tuning) allows us to recalibrate factory settings for better power delivery, cleaner fuel burn and smoother load handling. Whether you’re regularly towing, hauling gear across North Queensland or just want more out of your daily drive, we customise the tune to your specific needs. Tuning is available for utes, 4WDs and light commercial diesels across a range of makes and models.


  • ECU remapping & throttle response tuning
  • Safe tuning within engine & drivetrain limits
  • Upgrades for turbo, exhaust & intake efficiency


We also provide diagnostics for underperforming vehicles and can advise on supporting modifications to make the most of your tune.

Frequently Asked Questions

  • Is performance tuning safe for my vehicle?

    Yes—when done properly. Professional tuning works within the limits of your vehicle’s engine and transmission. It enhances efficiency and power delivery without overstressing components. Cheap or DIY tunes, however, can damage your engine. Always go with an experienced tuner who understands diesel systems.

  • Will tuning affect my fuel economy?

    In many cases, yes—positively. A well-tuned diesel engine often burns fuel more efficiently, resulting in improved economy, particularly under load. However, fuel savings depend on your driving style, the tune type and whether performance upgrades have been installed.

  • What’s the difference between a dyno tune and a remap?

    A remap adjusts your ECU software using pre-set tuning data tailored to your engine and goals. A dyno tune is done in real-time with the vehicle on a rolling road, allowing precise live adjustment based on how it performs under load. Both methods are effective, but dyno tuning offers the most accuracy.
