This DPChip is extremely compact around the size of a small mobile phone and is used on all Common-rail injected diesels including BMW X5 and Toyota DF-D engines. It features a harness with original manufacture’s plugs for ease of fitting and is pre-set to your vehicle by us. Further adjustable tuning is possible, either manually with the 10 pre-programmed power setting dial (as shown in the picture) or electronically via lap top tuning (at our premises or one of our official distributors). The DPChip has several features such as lap top tuning via USB and easy to fit plugs. Fitting takes less than 15 minutes on most vehicles.
