MoTeC M1 Firmware: MoTeC GPR Diesel

MoTeC GPR Diesel firmware license for MoTeC M1 ECU

MoTeC's M1 GPR Diesel Package is a versatile and adaptable platform for the operation of diesel engines.

This Package has been designed for direct injection, common rail, turbo diesel engines, but can also be used for naturally aspirated diesel applications. Many features from MoTeC's petrol GPR Packages have been reproduced in this Package, providing a familiar feel for current GPR users.

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

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.

ECU Variants

This Package is available for use with MoTeC's direct injection ECUs: M141 and M142. A Package variant for M130 and M150 ECUs is also available and is used in conjunction with an injector drive box fitted to some vehicles (e.g. Toyota Hilux).

The key difference between MoTeC's M141 and M142 ECUs is the maximum available Boost Voltage and Peak/Hold Currents for direct injector operation. Accordingly, the injector supply requirements of any engine must be considered when choosing an M1 ECU.

The following features in GPR Diesel have been specifically designed to run diesel engines:

• Operates diesel direct injected engines from 1 to 8 cylinders with inductive or piezo injectors and synchronous direct injection fuel pumps.

• Turbocharger boost pressure control of either a PWM solenoid or servo motor for use with a Variable Nozzle Turbo (VNT), wastegate, bypass etc. The boost control can be fully configured via a PID control system that gives the user full control over the response and stability of the system. The Boost Aim can be varied based on Fuel Mass, Engine Speed and Ambient Pressure.

• To ensure safe operation, a number of overriding Boost Limits can also be set. These limits may be based on Coolant Temperature, Engine Load, Exhaust Temperature, Inlet Air Temperature, Race Time, Gear, Vehicle Speed and Turbocharger Speed.

• Control of a throttle valve is also supported. This throttle valve can be used to assist engine shutdown or reduce power during Engine Overrun.

• Exhaust Gas Recirculation control via a servo motor, solenoid or stepper motor actuator. The EGR amount applied can be varied with Engine Speed and Fuel Mass. Compensations for Air Temperature, Coolant Temperature and Ambient Pressure can also be applied.

• A Start Off EGR Compensation can be used to avoid soot formation when the vehicle takes off. Separate EGR aims can be used for Overrun and Gear Shifts. The Throttle Servo or a Flap Actuator (EGR Cooler) can also be controlled during EGR requests.

• The Glow Plug Control system includes independent strategies to control the glow plugs pre-cranking, during cranking and post cranking. Each phase has tuneable compensations for Coolant Temperature and Battery Voltage.

• Ignition outputs are available for each cylinder to check the timing of the fuel injection.

• Advanced LTC Enable functionality ensures safe operation of Lambda sensors.

• 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.
