GPRP Pro is a sophisticated engine control Package centred around calculating and controlling engine torque via throttle opening and ignition control.

Built with race functionality and Paddle Shift Gearbox Control, this Package includes all the key characteristics of MoTeC's GPRP Package, plus Torque Control, Dual Plenum Fuelling and much more.

Cutting edge features that improve engine performance, driver consistency and tuning simplicity are combined to make a Package suitable for the highest levels of professional motorsport.

A GPRP Pro ECU fully integrates with other MoTeC products and provides pre-defined CAN messaging for current Displays, Loggers, E888, Video Capture Systems, GPS, ADRs, BR2, PDMs, SLMs and Keypads.

The GPRP Pro Package is available for use with MoTeC's M150 and M190 ECUs. A pinout example for the M150 follows.

A separate Package, GPRP-DI Pro (Part# 23667), supports MoTeC's M142 and M182 Direct Injection ECUs.

The GPRP Pro Package is based on MoTeC’s GPRP Package with the addition of the following features:

• Torque Based Throttle Control used throughout the Package:
  • Ignition Retard and Cut are also used for torque reductions. These are blended with the Throttle Based Control for fast response and seamless transitions;
  • Torque is relevant to vehicle acceleration for improved Traction Control;
  • Much faster control response and more accurate than Boost Control;
  • Improved drivability with a torque based throttle pedal and seamless transition between Throttle, Overrun and Idle Control;
