Just Autos V3 Multi-Map – 300 Series LandCruiser

Take total control of your 300 Series with the Just Autos V3 Multi-Map system—six fully custom maps, all switchable on the fly using your factory cruise control stalk. No extra buttons. No messy wiring. Just clean integration and serious functionality.

Map Modes:

• Stock+ – Slight bump in response and drivability while maintaining factory smoothness.

• Immobiliser – Cranks but won’t start. A clever theft deterrent that adds peace of mind.

• Idle Up / Winch Mode – Increases idle to 1500–2000 RPM for winching, jump starting, or battery charging.

• Tow Mode – Enhanced low-end torque and engine braking, perfect for heavy towing or off-road control.

• Power – Unlocks full power from the twin turbos with smooth delivery.

• Power+ – Lumpy idle, launch control, and sharp throttle response for performance driving.

Key Features:

• Cruise Control Stalk Switching – Flick to view map, hold to change. Retains all original cruise functions.

• Sport Shift Integration – Cruise control also enables sport shifting, giving you more control in manual mode.

• Just Autos Easy Throttle – Custom throttle mapping eliminates dead zones and lag for a snappy, predictable pedal feel.

• Built-in Engine Protection – Smart limits for EGT, boost, and torque help protect your driveline and engine under harsh use or failure conditions.

Version 3.1 delivers smoother turbo transitions, real-time torque control, and seamless usability whether you’re towing, touring, or giving it the beans.

With ECU remapping, you can expect significant improvement in your engine’s power, 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! As a standalone performance enhancement, ECU remapping is a smart investment for anyone looking to get the most out of their Toyota diesel engine.

Co-developed by 888 Racing and Just Autos, this custom intake pipe is built to suppress surge and smooth out the transition between the twin turbos. Designed for performance and reliability, it reduces the dip in power delivery and keeps your 300 Series pulling hard across the rev range. Engineered, tested, and tuned with real-world results in mind.

Experiencing elevated engine temps while towing, off-roading, or driving in extreme heat? Our upgraded heat exchangers are engineered to improve cooling performance compared to standard factory units.

By dissipating heat more effectively, these systems help reduce critical fluid temperatures, supporting better thermal management and more consistent engine operation—especially under load or in harsh environments.

Experience the benefits of our own in-house engineered Just Autos airbox—developed specifically to improve airflow and filtration. Designed to reduce dust ingress and airflow restriction, our airbox helps protect your engine from the harshest conditions while supporting more consistent performance.

the Just Autos airbox is tested and refined for durability, cooling support, and real-world driving demands.

Want more grunt and better performance? Our performance exhaust systems are designed exactly for that. They improve airflow, cut down backpressure, and can deliver noticeable gains in horsepower and torque, depending on vehicle configuration. Swapping out your standard factory exhaust for one of ours will give your vehicle’s performance a proper lift.

Smash tracks, not fuel filters. Our heavy-duty Fuel Filter Guard for the 300 Series is built for serious off-road punishment. Whether you’re crawling over rocks or blasting through creek beds, this underbody armour keeps your filter safe from sticks, stones, and anything else trying to ruin your weekend. Designed for 4WDers who don’t baby their rigs, it bolts up strong, shields tight, and holds its ground—just like your Cruiser should.

Whether you’re chasing the sleek, custom look of stainless or the clean, functional lines of a Safari, it all comes down to personal preference. Both options offer serious protection against water crossings and dusty tracks, raising your intake to keep your engine breathing clean in tough conditions. It’s all about the look you’re going for—functionality is a given.
