MOTEC M150 ECU W/GPR ROTARY LICENCE

MoTeC's M1 GPR Package is a versatile and adaptable platform for the operation of port-injected engines. 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 that may also include a sequential gearbox and many other features. Configurable engine synchronisation modes accommodate most modern engine triggering systems.

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.

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

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.

GPR FEATURES :

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

Closed loop lambda control support; requires optional LTC with Bosch LSU4.9 sensor or LTCN with NTK sensor.
Physical settings for engine displacement, fuel properties, and injector characteristics allow for simplified engine start-up prior to tuning.
