How Diesel Tuning Devices Work

Diesel Tuning Modules are specifically designed and tested to achieve enhanced performance by modifying the electronic diesel fuel injection parameter mappings. Through careful interaction of these parameter values and characteristics optimum performance of your engine be achieved. One of the reasons this optimisation is required is manufacturing variances and varying fuel qualities across the country, across the world. Vehicle manufacturers wish to produce one version of a vehicle for worldwide distribution. This means they must choose the lowest common denominators, and for go some performance gains.

The turbo boost pressure is not altered by our diesel performance modules, only dynamic parameter changes are made in real time to the electronic diesel fuel injection system, within the manufacturers specification. A number of engine parameters are modified, depending on the specific engine and its operating condition. These include a number of aspects, including fuel injection timing and volume., depending on the specific engine.
Increases in boost can cause ECU error codes if not managed carefully. Our diesel performance tuning modules permit the original ECU to handle all of its error and sanity checks. Unlike some other systems on the market, our modules has been tested in real world conditions from the heat of the deserts to the cold climates of the alpine regions, in day to day city driving to the demanding slogging off road outback usage. They are truly tested Australian tough!

Many of the DPChip Diesel Performance Tuning Modules also have adjustable tuning via a moveable connection. The Diesel Performance Tuning Module can also be tuned using a MS Windows computer (typically a laptop). This is a form of tune that can do considerably more than the manual adjustment. As well as overall power being able to be increased, the power can be moved further down or up the range and the power delivered can be varied to be smooth or aggressive.

Another great advantage of this is that if you decide to enhance your vehicle further, through maybe larger intercoolers, larger exhausts etc. you can easily adjust the Diesel Tuning Module to match the new modification so the full potential can be reached. Fixed map boxes and chips this is not possible and a new chip or box would be required - costing more money.

Power and torque can be felt immediately after the Diesel Performance Tuning Module is fitted. The throttle response is improved and particularly low and mid range torque is vastly improved, making the overall performance of the vehicle completely different. This is particularly valuable when precise throttle response is required in off road conditions. Not only that, but the improved power and torque mean that you can approach obstacles in a controlled manner, not relying on brute momentum to carry you through or over them.

When carrying loads and/or towing the extra power is also great advantage. The overall drive becomes more pleasurable and the engine in most instances actually runs smoother. As an example, one of our test cars was able to slash more than 9 seconds from a typical highway overtaking manoeuvre using our DPChip Performance Exhaust system and Diesel Performance Tuning Module. Nine seconds is a long way at the legal speed limit. See www.dpchip.com for more information.
