Share This Item:

This M142 Plug-In ECU Kit provides a complete replacement for the OE (original equipment) ECU for the Toyota Yaris GR 2020. Using existing wiring, the original fuel system and sensors, it delivers convenient installation with fully programmable control.

Using the optional Diff Loom (#61466) The kit now provides programmable rear Diff Control that integrates with the Drive Mode Switch.

Along with fuel, ignition, throttle and camshaft control, this Kit also supports other OE ECU features, including:

Selectable Drive Mode including Normal, Sport, and Track using OE controls
Head-Up Display
Direct injector with high pressure fuel pump control and secondary port injector control (saturated high-ohm injectors only)
Cruise control
All OE dash functionality including warnings

Drivers should be aware that specifically the following standard features do not work utilising this M1 Package: Active Cruise Control, Dynamic Stability Control, Low Speed Pre-Collision System and Lane Trace Assist.

This product does not interact with the Radar Collision subsystem on the vehicle. As a result continuous alerts may be visible in the dash central information display.

DIFFERENTIAL CONTROL :

This Kit now provides programable control of the active rear differential clutch of the Toyota Yaris.

Compatible with the OE Yaris 3 position Drive Mode Switch.

Numerous diff modes are configurable within the M1 Package, using MoTeC's 9 Position Switch (#56100).

This update requires the following components:

Diff Loom

61466 - TOYOTA YARIS GR 2020 DIFF LOOM

Purchased separately.
Firmware

TOYOTA YARIS GR 2020 G16E firmware must be version number 01.11.0099 and above.
Adaptor box

The Adaptor Box (PN 61460) included in the kit must be Version3.

OPERATION :

Reference Mode

The M1 Reference Mode in this Package is locked to the Toyota Yaris GR pattern.

ECU Power

The M1 ECU will be powered as follows:

When the push start button is pushed once.
When the M1 is connected to the M1 Tune application via Ethernet. Once on, power will remain when the M1 is connected to the M1 Tune application via Ethernet.

Engine Start

This feature operates identically to OE behaviour.

Driver Switches

Various in-car dials and switches are acquired over the CAN bus and assigned to Firmware resources to allow for mode switching in the ECU. See the Help for the main Toyota Yaris group in M1 Tune.

Fuel Pressure Control - (Lift Pump)

The vehicle uses a PWM controlled low pressure fuel pump (lift pump) which operates in closed loop. Desired fuel pressure is set in the Fuel Pressure Control Aim table.

Dash Override

If installed, the optional Dash Override feature can be enabled.

This feature can be enabled by holding down the Drive Mode Normal Switch for 5 seconds. This will cause the Secondary Brake Collision System, Pre-Collision Malfunction and Lane Trace Assist warning messages as well as the Dynamic Stability Control and Low Speed Pre-Collision System malfunction indicator lights to be hidden from the OE Dash.

Enabling this feature removes dash warning lights designed to alert the driver of malfunctioning Active Cruise Control, Dynamic Stability Control, Low Speed Pre-Collision System and Lane Trace Assist.
