4x4 diesel tuning services are available for most brands of 4WD utes and SUV vehicles. Modern 4X4 engines are managed by a complex network of interconnected components and sensors that manage everything from injector duration, injection timing, turbo boost, common rail pressure, ignition timing and the idling speed of your engine.
At the heart of these complex systems sits the ECU or engine control unit; a palm-sized metal box that contains the software programme (map) that tells your engine how to behave in response to inputs from the numerous sensors in your vehicle. We are specialists in 2WD and 4x4 diesel tuning / ECU remapping services.
When car manufacturers ship new vehicles, they typically load the ECUs with conservative maps that ensure their vehicles perform well in a variety of environmental conditions. For example; Toyota 4x4 diesel tuning for an ECU ensures that their Hilux and Land Cruiser models work equally well on the fast Autobahns in Germany, the rolling estates in England, the subtropical winding roads in Malaysia, the extreme heat conditions in Dubai, the freezing cold conditions in Sweden, the rugged off road conditions in Australia, and heavy loads towing boats, horse floats and caravans in New Zealand.
Manufacturers must also make provision in their 4x4 ECU tuning maps for customers who won’t service their vehicles regularly, and for countries that have lower quality fuel. It’s easy to see that compromises need to be made in order to cater for such a wide range of car tuning conditions - which is why the OEM factories need to restrict performance and impose limitations on engine capabilities.
By creating a new 4x4 tuning map and reprogramming your ECU for local conditions, we can unlock your engine’s full safe potential – adjusting settings to unlock previously inaccessible reserves of power, torque management, engine response, and in some cases improve fuel economy to enable your 4x4 to perform as well as it possibly can. We can tune most modern 4x4’s and Utes that are Turbocharged with Common Rail Diesel injection.
We offer three unique maps:
Power Tune - The perfect 4WD tuning for this is where we can extract really good gains in Power, Torque, Response and often we can save fuel assuming that driving style remains the same as before the tune. Typical Power and Torque gains are 25-30% depending on the vehicle with better response. This applies to both petrol and diesel powered vehicles with diesels typically seeing the biggest increase in low down torque. Check out the Power and Torque gains that Eurotune can typically achieve from your 4x4, Ute or SUV HERE. Just $995+GST
Towing Tune - If you do a lot of towing or carry heavy loads on a regular basis, this the 4WD diesel tuning map for you. These tunes are designed to ensure that your engine will be protected in tough conditions. You can expect 20-25% more Power and Torque which makes a huge difference on the hills or when starting off with big loads and getting across intersections. Just $995+GST
Economy Tune - For those who do a lot of kms, want some more power but also would like to save fuel, then the Economy Map is the best 4WD tuning for you. Typically customers will see up to 1 litre/100km improvement in fuel consumption on the basis that driving style remains the same. In addition there will be a 15-20% improvement in peak torque which always comes in handy for passing and getting out of the oncoming traffic quickly. Just $995+GST
Torque Management - Some vehicle manufacturers have torque limiting software embedded in the factory ECU map. When fitting larger aftermarket turbos and other power adding devices, the factory set torque limiter becomes a barrier to unleashing the planned power and torque from the modifications. Eurotune are able to turn this function off in the ECU so that the benefits from the fitted aftermarket parts can be realised. If the planned power gains are significant then thought needs to be given to the transmission and gearbox driveline suitability i.e. valve body, auto clutch pack, manual clutch etc. For reliability and drivability it’s all about matching the driveline components to the new power and torque goals.Just $395+GST or included at no extra charge when you order a tune at $995+GST
Our ECU tunes have been developed in New Zealand and on a dyno by Kiwis. This enables us to take into account New Zealand spec. vehicles, local fuel quality, typical load and towing duties and Aotearoa terrain to provide the best blend of performance improvements. i.e. More Power – More Torque – More Response – Less Fuel.
We tune most brands of 4x4’s Utes and SUV’s e.g. Ford, Holden, Jeep, Land-Rover, Mazda, Mercedes, Mitsubishi, Nissan, Toyota, Volkswagen, Isuzu.
Our diesel tuning specialists are continually developing tunes for new vehicles as the manufacturers launch them. If you’d like to see the performance that Eurotune can unleash from your vehicle, just click on the MY VEHICLE button below.
