TUNING, RE-MAPPING & MULTIMAPPING

Tuning, remapping, and multimapping optimise your Toyota’s performance by adjusting engine settings for more power, efficiency, and adaptability.

ECU Remapping

Looking for more from your diesel 4WD? Many factory-tuned diesel engines are designed to meet broad global standards, not the unique conditions of Australian terrain or your driving preferences. That’s where tailored ECU tuning can make a real difference.

At Just Autos, we specialise in ECU remapping for the 200 & 300 Series Land Cruisers, VDJ70 Series, Hilux, and Prado—enhancing power and torque without requiring hardware modifications.

The result? A smoother, more responsive drive that can feel significantly more refined. And when combined with our performance hardware upgrades, the results speak for themselves.

MuLTI-MAPPING

Why stay locked into a single tune when you can switch between multiple? Just Autos’ Multi-Mapping technology enables you to select from custom performance profiles using your vehicle’s existing cruise control switch—no extra buttons or modifications needed.

Each map is tailored to support different driving scenarios, allowing you to prioritise power, torque, drivability, or reliability when it matters most. Whether you’re towing, off-roading, or cruising, our multi-map setup offers flexible control, tuned to your driving preferences.

Tuning & TCM

At Just Autos, we specialise in ECU remapping for the 200 & 300 Series Land Cruisers, VDJ70 Series, Hilux, and Prado. Our tuning solutions are designed to help improve power and torque without requiring hardware modifications.

We also offer advanced TCM tuning, including torque converter lock-up kits that integrate with the vehicle’s existing transmission control system. In most configurations, drivers can control the system using existing factory buttons, offering a user-friendly and responsive experience.

The result? A more refined, responsive drive tailored to your vehicle and driving style. When paired with performance hardware upgrades, the improvements can be substantial.
