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

Using the optional Diff Loom (#61466L) the kit provides programmable rear Diff Control that integrates with the Differential 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
• OE dash functionality including warnings

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 and the following dash lights may be illuminated:

	DSC (Dynamic Stability Control) Warning
	Low Speed Pre-collision System Indicator

Installing the optional CAN ISO Gateway feature prevents alarms associated with these systems showing up on the dash.

This product includes CAN messaging for full OE vehicle integration. The Package caters for OE vehicle systems such as power steering, ABS, starting systems and dashboards.

The following table shows compatible vehicles.
