This M142 Plug-In Kit provides a complete replacement for the OE (original equipment) ECU for the Toyota GR86 or Subaru BRZ with the FA24D Engine. Using existing wiring, fuel system and sensors, it delivers convenient installation with fully programmable control.

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

• Push button start
• Direct injector with high pressure fuel pump control and secondary port injector control (saturated high-ohm injectors only)
• Cruise control
• Air Conditioner Control
• All OE dash functionality including warnings
• ABS System integration
• Electronic Power Steering Integration

The supplied start file contains all calibrations and settings for the sensors, direct fuel injectors, ignition coils, knock control, throttle servo, camshaft, cruise control. It also has been calibrated to match the OE factory fuelling, ignition and camshaft phasing. This saves a significant amount of time as it shortcuts the setup process.

Included are many ancillary features commonly found on race cars such as; anti-lag, driver switches (e.g. pit switch, launch enable, boost trim) gearbox control,intercooler sprays, launch control, coolant pumps and traction control

The ECU fully integrates with other MoTeC products and provides pre-defined CAN messaging for all current Display Loggers, loggers, LTCs, E888, VCS, GPS, ADR, BR2, PDM and SLM.

As a result continuous alerts may be visible in the dash display and the following dash lights may be illuminated:
