The ASNU GDI Adapter Box has been designed to drive Gasoline Direct Injection (GDI) injectors with an approved supply of current and voltage to simulate injector electronic operation as on the engine. Correct Electronic Operation is critical when examining the injector’s response to changes in mS & RPM. Examination of the injectors Fuel Distribution and Atomisation is equally critical to the Engine's Correct Running, Performance, Fuel Economy and Emission Outputs. Even the slightest irregularity in the Fuel Spray pattern would result in illumination of the Engine Check Light, but with no specific cause identified.

GDI injectors are difficult and time consuming to remove and re-fit! Would you fit a new set of injectors without ensuring they are working correctly?
