ASNU Piezo Adapter Box

Diagnosing Injector Performance

Piezo injecton is the current system of choice of major executive vehicle manufacturers. Piezo injectors can respond so quickly that they can allow the vehicle to run at incredible air/fuel ratios of up to 60:1 in some engines. Compared to standard vehicles running at 14:1 air/fuel ratios, this means the minimum amount of fuel is used and the exhaust emissions are virtually non-existent, while still maintaining excellent drivability and performance.

In conjunction with a world leading vehicle manufacturer, ASNU have created this purpose built adapter box.

  • Easy to use test functions using the latest Piezo technology
  • Easy connections to Classic GDi Machine or GDi adapter Box.
  • Universal fittings for Piezo type injectors
  • Dimensions: 300mm x 190mm x 220mm in a robust metal casing.

ASNU GDI/FSI Adapter Box

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.
