The SDI ECU is the perfect solution for integrated direct injection engine management. Based on the highly popular S8 architecture the SDI just has less inputs and outputs for those GDI applications that don’t require the complexity of the full S8.

The SDI is designed to directly control and drive all Gasoline Direct injectors including parts from Ford, GM and Bosch (including Bosch Motorsport types) without the need for an external driver box. As standard it caters for 4 Cylinder engines but we can provide for more cylinders via the use of our S12 Ecu and GDI Boxes
