GPR Features Maintained

The following features from MoTeC’s GPR Package are maintained in the GPR Automatic Transmission Package:

  • Operates port injected engines from 1 to 12 cylinders (M150 or M190) or 1 to 8 cylinders (M130 or M170).
  • Configurable engine synchronisation modes for many common engine types. Refer to the Engine Synchronisation Modes section for current details.
  • Configurable top dead centre for each cylinder allows for odd-fire engines.
  • Configurable ignition output pin for each cylinder allows for coil-on-plug or wasted spark and distributor ignition systems.
  • Configurable on-board knock for each cylinder with up to 4 assignable knock sensors (hardware dependant) and selectable centre frequencies.

  • Dual bank lambda control supported; requires optional LTC with Bosch LSU4.9 sensor or LTCN with NTK sensor.
  • Physical settings for engine displacement, fuel density+molar mass, stoichiometric ratio and injector characteristics allow for simplified engine start-up prior to tuning.
  • Quick and easy engine tuning using engine efficiency map.
  • Engine load modelling based on inlet manifold pressure and inlet manifold temperature. Alternatively, for example, when using individual throttle bodies, throttle position can be used.
  • Control of 2 port injectors (peak&hold or saturated) per cylinder ('high/low' configuration) with tunable balance table.
  • Control of one port injector (peak&hold or saturated) per cylinder.
