DIesel Tuning

diesel engine tuning and ECU remappingEurotune provide diesel tuning services for most Turbocharged Diesel Engines - Cars, Vans, Motorhomes, Utes, 4x4's and Trucks. Modern diesel engines are managed by a complex network of interconnected components and sensors that manage injector duration, injection timing, turbo boost, common rail pressure, idling speed and the responsiveness of your engine.
At the core of these complex systems sits the ECU or engine control unit that contains the software programme (map) that tells the engine how to respond to inputs from the numerous sensors on the vehicle. We are specialists in diesel tuning / ECU remapping services

When manufacturers ship new vehicles, they typically load diesel ECUs with very conservative maps that ensure their vehicles perform well in a broad range of climatic and terrrain conditions. For example; when setting the ECU in the OEM factory, the manufacturer must ensure that their Cars, Utes, 4x4's, Vans, Motorhomes and Trucks work equally well on the fast American motorways, the undulating terrain in the United Kingdom, the sub-tropical weather and mountainous roads in northern Thailand, the extreme temperatures across the Middle East, the icy winters in Ukraine, the rugged and arid off road landscapes of Australia, and the alpine passes and gravel roads in backcountry New Zealand. 

Manufacturers must also anticipate in their  ECU tuning maps that some customers con’t service their diesel vehicle regularly, and that 3rd world countries have variable quality in fuel stocks. Obviously, some compromises are being made in order to accomodate such a wide range of diesel tuning circumstances. This is why vehicle Manufacturers need to restrict performance and impose limitations on a diesel engine's operational parameters. And thats why we offer diesel performance upgrades. 

4WD diesel tuning servicesBy creating a new diesel 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 many cases improved fuel economy to enable your vehicle to perform as well as it possibly can. We provide diesel tuning services for most vehicles fitted with turbocharged diesel engines and common rail diesel injection. 

We offer two unique maps:

Power Tune - Diesel Tuning where we 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. Check out the Power and Torque gains that Eurotune can typically achieve from your Car, 4x4, Ute Van, Motorhome or SUV HERE. Just $995+GST

Towing Tune - If you do a lot of towing or carry heavy loads on a regular basis, this is the 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 for Cars, Vans, Utes, 4x4s and Motorhomes

Diesel tuning specialist - Auckland, Tauranga & DunedinOur ECU maps have been developed in New Zealand and on a dyno by Kiwis. This enables us to take into account the specifications of New Zealand vehicles, our realtively poor diesel quality, typical load and towing duties in Aotearoa terrain to provide the best blend of performance improvements. i.e. More Power – More Torque – More Response – Less Fuel. 

Our Diesel Tuning and remapping is avaialable for diesel engines used by DAF, ERF, Ford, Fuso, Holden, Hyundai, Isuzu, Iveco, Jeep, Land-Rover, Kenworth, Mack, MAN, Mazda, Mercedes, Mitsubishi, Nissan, Scania, Toyota, Volkswagen and Volvo

We are continually developing diesel tuning maps for new vehicles as the manufacturers launch them. If you’d like to see the performance that Eurotune can unleash from your diesel vehicle, just click on the MY VEHICLE button below.
