Based on MoTeC's successful M1 GPR Package, the GPRP Package is a versatile and adaptable platform for the operation of port injected engines that include paddle shift gearbox control using switched actuators. This single product can be configured over a huge range of complexities, from controlling a simple engine to a multi-throttle, quad cam boosted engine with two injectors per cylinder and many other features. Configurable engine synchronisation modes accommodate most modern engine triggering systems.

Included are many ancillary features common to 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 pump, gear shift air pump and traction control. It also caters for many systems found on modified road vehicles that may be useful in a racing context, such as air conditioning control and four definable control outputs.

This Package is available across MoTeC's range of M1 port injection ECUs (M130, M150, M170, and M190). It seamlessly integrates with other MoTeC products and provides pre-defined CAN messaging for all current Display Loggers, Enclosed Loggers, Power Distribution Modules and other devices including E888, VCS, GPS, ADR, BR2 and SLM. Example wiring schematics are provided for basic operation with each ECU variant.

  • GPRP (Race with Paddle shift)
  • GPRDI (Race with Direct Injection)
  • GPRPDI (Race with Paddle Shift and Direct Injection)
    These variants that can be configured to suit a wide range of applications.

Development Solutions - Those who are skilled at coding can now develop fully customised control strategies at the firmware level, creating unique ECU functionality for themselves or other customers. Developers can build custom controls into an existing package, or create a new project from scratch. In either instance, the resulting firmware can be loaded into a single Development ECU or rolled out for customers around the world to purchase.

Ruggedised - Sometimes an extra level of protection for electronic components is required, such as marine applications or environments subject to dirt or dust. Our Ruggedised M1 hardware ensures maximum longevity under these extreme conditions.
