With ECU remapping, you can expect significant improvement in your engine’s power and even fuel efficiency, delivering an enhanced driving experience that is both smoother and more responsive. Our custom ECU tuning process will take advantage of the untapped potential in your engine, without the need for any costly hardware upgrades or modifications – though we offer a range of upgrades that complement a newly tuned ECU well!

Multi-mapping is a complex service offering that Just Autos provides for a variety of Toyota engines and models. Our experts connect our tuning software which works in conjunction with the ECU’s onboard processor to create multiple maps, or sets of parameters, that can be stored in the ECU. These maps can then be switched between as needed, allowing the ECU to adjust its parameters for different conditions and environments.

Our ECU-based transmission lock-up kits deliver the ultimate performance upgrade for Toyota owners seeking increased torque when you need it, and superior reliability. These solutions significantly reduce transmission temperatures by preventing excessive heat from converter cycling, even under high RPM stress. You’ll experience more direct power delivery to all wheels, enhanced driving responsiveness, and reduced brake load thanks to the more efficient drivetrain. Perfect for off-road enthusiasts, our intelligent system automatically activates lockup in ideal conditions while disabling it during low-RPM acceleration or technical rock driving when extra torque is crucial.

Boost your performance with a Just Autos airbox upgrade. Our quality systems improve airflow and filtration, guarding against dust and blockages that kill performance and cause premature wear. We use top aftermarket brands, ensuring our airboxes work perfectly with our cooling upgrades (intercoolers or fan kits). Get cleaner air, cooler running, and the power your diesel deserves.

Want more grunt and better performance? Our performance exhaust systems are designed exactly for that. They improve airflow, cut down backpressure, and deliver a real power boost, more horsepower and torque, letting you get the most out of your engine. Swapping out your standard factory exhaust for one of ours will give your vehicle’s performance a proper lift.

Looking after your engine’s health and helping it last longer is what our Just Autos intercooler upgrades are all about. By cooling the air before it enters the engine, they reduce heat stress, allowing your motor to produce power more safely and efficiently. The best intercooler upgrade from Just Autos depends on your specific Toyota model and its current setup – whether it has a factory front-mount, top-mount, or no intercooler at all. We’ll help you find the right solution.

This latest generation turbo delivers a serious boost in performance, giving you impressive gains in power and torque right where you feel it. Built with genuine quality and designed for durability, the GEN-iii offers reliable power you can count on, even when pushed hard in Aussie conditions.

Our upgraded injector replacements deliver the precise fuel flow your engine needs, whether you’re supporting other performance mods or just aiming for reliability. They’re crucial for safely unlocking serious power gains with a tune, and can offer better fuel atomisation than worn factory units for smoother running.

An upgraded transmission cooler extends the life of your transmission by keeping your fluid temps way down compared to the factory setup. It does this by drastically reducing wear and helping prevent costly gearbox failures. It’s vital protection for reliability and longevity, giving you peace of mind when you’re towing, going on long trips or hitting the beach.

Planning on tackling water crossings or hitting dusty outback tracks? A snorkel is essential kit for your 4WD. It raises your engine’s air intake nice and high, giving you crucial protection against sucking in water during creek crossings – saving you from potentially wrecking your motor. Plus, it helps grab cleaner air above the thick dust, looking after your engine’s health.
