MoTeC’s GPR Rotary Package is a versatile and adaptable platform for the operation of rotary engines with up to four rotors.

This single product can be configured over a huge range of rotary engine configurations, from controlling a simple, naturally aspirated 13B to a multi-throttle, boosted quad rotor with three injectors per rotor.

This Package also includes vehicle integration for modern rotaries such as the Mazda RX7 and RX8.

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

Compatibility

The product fully integrates with other MoTeC products, and provides pre-defined CAN messaging for all current  MoTeC Dash Loggers, E888, V2 , GPS, ADR , BR2 , PDM and SLM. A Vector database (.dbc) file is available on request.

ECU Variants:

The Package is available for use with MoTeC’s M130, M150, M170, M190 ECUs.

Vehicle Compatibility

This product also includes CAN messaging for OE vehicle integration with the Mazda RX8. This enables OE vehicle systems such as power steering, ABS, TPMS, transmission and instrument cluster information.

WHAT’S IN THE BOX

Includes:

• MoTeC M1 ECU
• Enable for the MoTeC M1 ECU
• Firmware Licence (for the GPR Rotary Package)
• Logging Licence: Level 1 upgrade available
• Analysis Licence: i2 Standard upgrade available

ROTARY SPECIFIC FEATURES

The GPR-Rotary Package is based on MoTeC’s GPR Package with the addition of the following rotary engine-specific features:

• Operates port injected rotary engines from 1 to 4 rotors.

• Configurable engine synchronisation modes for common rotary engines. Refer to the Engine Speed Modes section for details.

• Configurable leading and trailing ignition outputs for each rotor. The trailing ignition timing can be defined as either an angle relative to the leading ignition (i.e. split angle) or TDC.

• Configurable on-board knock detection for each rotor with up to two assignable knock sensors and 4 selectable centre frequencies.
• Control of up to three injectors per rotor with user definable tables to control the fuel contribution of each injector.
• Coolant and engine oil temperature compensations for engine speed limiting, ignition timing, fuel volume and boost limiting.
• Supports control of a Sequential Shutter Valve with fuel injector integration as found on the Mazda RX8.
• Supports control of VFAD, VDI and APV inlet manifold valves found on Mazda rotaries.
• Diagnostic checking of SSV, VFAD, VDI and APV valves via feedback position sensors.
• User configurable engine efficiency table with adjustments based on the state of the SSV, VFAD, VDI and APV valves.
• Supports control of a stepper motor-based Metering Oil Pump. This includes diagnostics and a warning system to detect if there is a failure of the components.
• Supports dual speed cooling fans via three relay outputs, as found on Mazda rotaries.
• Cruise Control for DBW equipped vehicles.
• CAN Integration, for the Mazda RX8, to enable the operation of the power steering, transmission and ABS. Wheel speeds, steering angle, fuel tank level, tyre pressure monitoring and park brake data are also received from the CAN bus for use in the ECU.
