This kit provides a complete replacement for the factory Subaru ECU. It utilizes the existing vehicle wiring and sensors to deliver plug-in convenience. Using an integration patch harness and MoTeC M142 ECU the kit delivers fully programmable engine control to the platform while maintaining stock vehicle systems functionality. The M1 ECU is supplied with firmware preloaded and is based on MoTeC’s GPR-DI package with additional features unique to the 2015 – 2019 Subaru WRX and motorsport demands.

The kit comprises of the M142 ECU, “Plug-N-Play” patch harness, MoTeC LTC and LSU 4.9 lambda sensor.

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

  • Push button start
  • Air conditioner control
  • High and low speed fan control
  • Fuel lift pump control
  • Cruise control
  • Alternator control
  • Brake vacuum pump control

The supplied start file contains all the calibrations and settings for the sensors, direct fuel injectors, ignition coils, knock control, throttle servo, camshafts, alternator control and fuel lift pump control. Settings for fuel delivery, ignition timing and camshaft phasing have been calibrated to a vehicle
using common “bolt on” parts.

This saves a significant amount of time by shortcutting the setup process. Users can begin tuning to their desired power and modifications right away with the assurance of a safe base tune.

Note: Factory tumble generator valves (TGVs), Eye-Sight and CVT are not  supported. The TGVs must be removed prior to the installation of this kit.

Included are many ancillary features commonly found on race cars such as anti-lag, rolling launch, driver switches, gearbox control, knock control, intercooler spray-bars, launch control, coolant pumps, and traction control.

The product fully integrates with other MoTeC devices, providing pre-defined CAN messaging for all current Displays/Loggers, LTC’s, E888, VCS, GPS, ADR, BR2, PDMs and SLMs.
