ECU Remapping & TUNING FOR 300 series landcruiser

ECU remapping involves reprogramming your vehicle’s Engine Control Unit (ECU) to optimise engine performance. This process can help increase power and torque output and is designed to enhance throttle response and drivability.

It’s a cost-effective way to recalibrate your engine’s performance characteristics—without the need for hardware modifications—making it a popular upgrade for drivers looking to improve engine responsiveness and overall feel.

MuLTI-MAPPING 300 series landcruiser

Just Autos offers advanced ECU multi-mapping services suitable for Toyota diesel vehicles, enabling drivers to switch between multiple engine performance maps tailored to various driving conditions. This technology allows for quick adjustments to the ECU’s parameters without manual reprogramming, enhancing engine efficiency across different terrains.

 

A custom-installed switch within the vehicle’s interior facilitates seamless transitions between maps, providing optimal performance whether you’re towing, off-roading, or seeking maximum power output.
