OPERATION :

When the M142 ECU is installed according to the included wiring pinout, this package mimics most aspects of OE operation as follows.

Start System

The OE vehicle utilises either a conventional ignition key or an immobiliser key fob to control power supply to the ECU and to crank the engine. The M142 package does not interact with the OE starting system, so modification to the OE wiring harness may be required if the package is not used with a purpose-built wiring harness for racing applications.

Air Conditioner

A function group is provided for direct wiring to air conditioner components, including refrigerant pressure sensor and air conditioner compressor clutch. Enable conditions cater for multiple choices including throttle position, engine speed, and temperatures. For these functions to be available the vehicle wiring may need to be modified, and inputs and outputs defined.

Power Steering

No user interaction or settings are required.

ABS / Stability

While this product uses some sensor information provided by these systems (for example wheel speeds) no further interaction occurs.

Accelerator Pedal

Ford Fiesta OE systems use a pedal with two outputs: a pulse width output which is wired direct to the ECU, and a voltage output which is wired to the IPC (instrument panel cluster), and then transmitted to the ECU via CAN messaging. The M142 solution requires both signals to be wired directly to the ECU as detailed in the included pinouts.

As many racing applications make use of pedal boxes with two voltage outputs, this is also catered for in the package. Refer to help content in the Throttle Pedal Sensor group of the package.

Coolant Shutoff and Coolant Bypass

Ford 1.6 SCTi engines have a shutoff valve and a bypass valve which may be used to alter cooling system behaviour. Settings for these devices are found in the Ford Fiesta ST Coolant Shutoff and Ford Fiesta ST Coolant Bypass groups of the M1 package.

Turbocharger Wastegate and Bypass

Ford 1.6 SCTi engines have a conventional wastegate solenoid and a compressor bypass valve. Settings for the wastegate are found in the Boost group, while settings for the bypass are found in the Turbocharger Bypass group of the M1 package.

Low Pressure Fuel Pump (Lift Pump)

Ford Fiesta ST vehicles control the low pressure fuel pump (lift pump) via an FPDM (Fuel Pump Driver Module). This device is not controlled in this package, so a normal low pressure pump and relay should be substituted.

Power Relays

Ford Fiesta ST vehicles control the PCM relay from the ECU. When the M142 ECU is installed according to the included wiring pinout, these outputs may be configured from the ECU Power Relay group of the M1 package.

Some variants of the vehicle may control these relays independently, so actual behaviour may not always match the settings in the M1.
