About Digital Power Box PDD Diesel Chiptuning Tuningchip

With the Pumpe Duese or unit injection system, 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 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.Product Overview:- For PD/unit injection systems- Increase in power and increase in torque- Original ECU settings are not altered- Original VAG (Volkswagen Audi Group)connectors- Will not harm your engine; does not increase injection pressure; uses temperature-compensated electronics- Will not void vehicle warranty- Will not alter engine diagnostics functioning- Will not interfere with engine error code sensing- Does not change the service intervals required for your vehicle- Will not alter vehicle emissions - 3-year limited warrantyDigital PowerBox PDD Signal Variation SwitchThe digital PDD PowerBox has a signal variation switch with 16 positions. Using a small screw driver, higher output can be achieved by turning the HEX switch to a higher setting.
