4WD & Diesel Tuning

At ECU Enhancements, we specialise in custom-calibrated remapping for modern diesel common-rail engines. Whether you are touring the Outback in a Landcruiser OR daily driving a Ford Ranger, or towing heavy loads with a HiLux, our mobile service brings workshop-grade engineering to your door. The trusted choice for 4WD diesel tuning.

Reliable Power

We tune within safe, factory-specified tolerances. Our goal is smooth, usable power, not just 'bragging rights' numbers that threaten your engine's longevity.

Towing Torque

Gain the torque where you need it most. We focus on the mid-range RPM, making overtaking and steep climbs effortless, even with a caravan or trailer attached.

Efficiency Gains

Optimized combustion means better fuel efficiency. Many of our customers report noticeable improvements in economy, especially during highway driving and towing.

Why Remap Your Diesel 4WD?

Safe Towing: We increase low-end torque so your transmission hunts for gears less often, reducing heat and drivetrain stress.

Fuel Efficiency: By optimizing the air-fuel ratio (AFR) and boost pressure, most 4WDs see a 5-10% improvement in fuel economy.

Reduced Turbo Lag: Sharper throttle response makes merging into Melbourne traffic safer and more predictable.

ECU Remapping & Calibration

Custom tuning for all major diesel platforms. We adjust fuel, boost, and timing maps to suit your specific vehicle modifications (exhausts, intercoolers, etc.).

DPF & EGR Solutions

Are you having DPF warning lights or EGR issues? We offer professional diagnostic, cleaning, and software-level solutions to get you back on the road.
