ECU Remapping
Just Autos have the master tuning hardware and software required to complete custom ECU remaps of the factory ECU in your turbo diesel vehicle. Our ECU tuning can be performed via the ODB diagnostic port. This means that your ECU does not need to be removed or tampered with.
Just Autos can remap your vehicle’s ECU to suit your needs; towing, performance, economy – you name it and we will custom tune it. We can also provide dyno tuning on our in house Dyno Dynamics dynamometer.

Towing & Touring
At Just Autos, we specialise in creating performance packages designed for towing and touring, which means creating a package that not only can provide the torque and power that’s needed, but which does so without sacrificing reliability. Key factors when tuning for towing and touring are: Efficiency; Reliability; Drivability; Torque & Power.
We design all our performance packages with these key factors in mind, using only components that are of high quality and that have been tested/proven to provide the result and reliability that we require.

Turbos & Injector Upgrades
Just Autos offer a wide range of bolt-on turbo upgrades from G Turbo. The wide variety of turbos we offer can suit the majority of 4WD/4X4 turbo diesel applications, whether you’re towing, touring, taking your car up to the beach, or just day-to-day driving, we will have an upgrade to suit.

Airbox & Intercoolers
At Just Autos, we can provide a wide range of airbox upgrades to help with airflow efficiency and filtration. Airbox design and operation can be a difficult thing to get right, but working with a few aftermarket part suppliers, Just Autos can provide the right upgrade for your vehicle.

HKS
The HKS FCON-iD is a piggyback computer that is hard wired into the vehicles factory ECU. This enables you to have more control over the vehicles factory base tune. Just Autos custom tune your vehicle on our in-house Dyno Dynamics Dynamometer.
