The GPA-DI Package is a versatile and adaptable platform for the operation of direct injected engines up to twelve cylinders (hardware dependent) that use inductive direct injectors and synchronous direct injection fuel pumps, such as Bosch HDP5 or Hitachi HFS034.

This Package is designed for automotive aftermarket applications.

For race applications, refer to the GPR-DI Package (part number 23008).

Included are numerous ancillary features common to race cars, such as driver switches, knock control, intercooler sprays and gearbox coolant pumps. It also caters for many systems found on modified road vehicles that may be useful in a racing context, such as air conditioning control.

This Package is available across MoTeC's range of M1 port injection ECUs (M130, M150, M170 and M190). The product provides pre-defined CAN messaging for full integration with other MoTeC products like Display Loggers, Video, Power Distribution Modules, Expanders, Shift Lights and more.
