PowerBox from MAL Electronics GmbH - made in germany How does the PowerBox work? With the PD (Pumpe Duese) unit injection system, the diesel fuel is heated to a very high temperature due to its thermal properties. The direct injection system has a temperature sensor that communicates with the Electronic Control Unit (ECU). When diesel fuel is heated to substantially higher temperatures, its density decreases. When this occurs, the fuel temperature sensor communicates the change, and the ECU compensates by injection more fuel for combustion.This is where the PowerBox intervenes. Integrated electronics communicates a higher temperature to the ECU, causing more fuel to be injected. The additional fuel is burned along with the excess air, which leads to a proportionate increase in output. The increased fueling will not override the safe operating parameters of your engine and does not change or interfere with ECU functioning. Compatibility The PowerBox PD includes plugs that are compatible with those originally installed in your vehicle, and it easily installs directly to the fuel temperature sensor. With illustrated instructions provided, an inexperienced driver can complete the installation in just a few minutes on most vehicles. The PowerBox PDadjust will not override the safe operating parameters of your engine and does not change or interfere with ECU functioning. Power adjustment setting The PowerBox PD has an adjustment screw that has been pre-set to provide a modest improvement. However, most vehicles require a higher setting to achieve optimal power gains. The unit can be easily adjusted by using a small screw driver.
