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 an immobiliser key fob to control power supply to the ECU and to crank the engine when the Start button is pressed. The M142 package does not change this behaviour.

Air Conditioner

There is no interaction between the M1 package and the air conditioner system.

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.

Turbocharger Coolant Pump

This pump may be controlled by configuring the Coolant Pump After Run subsystem in the M1 package. When the M142 ECU is installed according to the included wiring pinout, duty cycle should be set to -100% to effect high-side output drive.

Coolant Thermostat

MINI N14 engines have a heated thermostat which may be used to alter cooling system behaviour. Settings for this device are found in the MINI R56 Coolant Thermostat group of the M1 package.

Power Relays

MINI R56 vehicles control the DME and start relays from the ECU. When the M142 ECU is installed according to the included wiring pinout, these outputs may be configured from the MINI R56 Power 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.

Purge Canister

A simplified purge strategy is available and may be configured from the MINI R56 Fuel Purge group of the M1 package.
