The GPR-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.

In addition to the primary direct injectors, secondary port injectors may be configured.

Included are many ancillary features commonly found on race cars, such as anti-lag, driver switches (pit switch, launch enable, boost trim, etc.), gearbox control, knock control, intercooler sprays, launch control, gearbox coolant pumps and traction control. Also accommodated are many systems found on modified road vehicles such as air conditioning control.

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.

FEATURES :

  • Operates gasoline direct injected engines from 1 to 12 cylinders with inductive injectors and synchronous direct injection fuel pumps (M142 suits up to 8 cylinders, M122 up to 4 cylinders). Refer to the Engine Compatibility section for known applicable engines.
