MoTeC M1 Firmware: MoTeC GPR Rotary

MoTeC GPR Rotary firmware license for MoTeC M1 ECU

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.

This firmware is available across MoTeC's range of M1 port injection ECUs (M130, M150, M170 and M190). 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.

GPR firmware incorporates additional advanced features over GPA, featuring sequential gear shift control (manual lever based), staged/secondary injection, anti lag, traction control and launch control

When ordering this firmware combined with a new M1 ECU, enter 0 for the serial number.

Ensure your serial number is accurate. This license is not refundable and cannot be moved to a different serial number after ordering.

Rotary 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.

• Like anything, the MoTeC M1 requires knowledge and experience to gain the best results. While we are happy to answer technical questions, purchase of this M1 firmware does not come with unlimited tuning support. We can quote tuning for your particular setup, refer you to someone in your area, or if you prefer to do it yourself (and lack the experience) then we can also quote training.

• This firmware is for closed course competition vehicles only. It does not meet federal emissions requirements.
