Modern Commercial Van engines like Ford Transit and Mercedes Benz Sprinter etc 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.
When vehicle manufacturers ship new Commercial Vans, they typically load the ECUs with conservative maps to ensure their vehicles perform in a variety of very different environments. For example; Mercedes need to ensure their Sprinter Van engine works equally well on the fast Autobahns in Germany, loaded with cargo doing stop start trips as a courier, doing long haul trips as a luxury people mover, loaded up as a tractor trailer unit hauling cargo; and doing that in every continent of the world in a wide range of temperatures, humidity, loads and terrain.
Manufacturers must also make provision in their ECU tunes for countries that have lower quality and variable octane fuel like New Zealand. It’s easy to see that compromises need to be made in order to cater for such a wide range of conditions – which is why the OEM factories need to restrict performance and impose limitations on engine capabilities.
By creating a new map and reprogramming your ECU for New Zealand conditions, we can unleash your engine’s full safe potential – adjusting settings to unlock previously inaccessible reserves of power, torque, engine response, and in some cases improve fuel economy to enable your Commercial Van to perform as well as it possibly can. We can tune most modern Vans that are Turbocharged and have Common Rail Diesel injection systems.
Two formats for Commercial Van ECU Maps
Power Tune – the perfect tune for those who run their Van with medium loads and just want to be able to keep up with the traffic on the hills, cruise effortlessly on the open roads at legal speed limits and have plenty in reserve for passing and getting out of the kill zone.
We provide excellent gains in Power, Torque, Response and often can improve fuel consumption assuming that driving style remains the same. Typical Power and Torque gains are 25-30% depending on the vehicle; and there’s better engine response.
Towing Tune – if you usually have a fully laden Commercial Van and maybe pull a trailer behind as well, then our Towing Map is the right tune for you. These tunes are designed to ensure that your engine will be protected in maximum load tough conditions. You can expect 20-25% more Power and Torque which makes a huge difference on the hills and will help reduce the vehicles behind you getting impatient because you can now drive at the approved speed limit.
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 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.
Our modifications to ECU mapping have been developed in New Zealand on a dyno buy experienced Kiwis. This enables us to take into account New Zealand specification vehicles, local fuel quality and typical terrain to provide the best blend of performance improvements. i.e. More Power – More Torque – More Response – Less Fuel
We tune most brands of Commercial Vans e.g. Ford, Hyundai, Iveco, LDV, Mercedes, Nissan, Renault, Toyota, Volkswagen etc and are continually developing tunes for new vehicles as the manufacturers launch them.
