This M142-based Kit is the latest addition to our range of Plug-In engine management solutions for Toyota's race and rally-bred GR models, providing the tuning power of MoTeC's M1 platform with the convenience of plug and play installation.

Utilising the vehicle's existing wiring, fuel system and sensors, this is a complete replacement for the OE ECU on left and right hand drive 2023 models powered by the G16E-GTS 1.6L turbocharged engine.

MoTeC's GR Corolla Kit supports OE functionality, including:

  • Selectable Drive Mode including Normal, Sport, and Track using the car's factory 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

Note: Active Cruise Control, Dynamic Stability Control, Low Speed Pre-Collision System and Lane Trace Assist are not supported. This product does not interact with the Radar Collision subsystem in the vehicle. Please visit MoTeC's GR Corolla ECU Kit webpage for further details.

    • Intercooler temperature and spray control.
    • Lap distance, time and number via BR2 or switched input, with split and sector options.
    • Vehicle speed limiting (pit speed control).
    • Launch control
    • Race time system with tables for ignition timing trim, fuel mixture aim, boost limit, and throttle limit.
    • Configurable anti-lag with ignition timing limit, fuel volume trim, ignition cut, fuel cut, engine speed limit, boost aim and throttle aim tables.
    • Traction control with tables for aim main, aim compensation, control range
  • Additional optional integrations:
    • Support of MoTeC devices: E8XX, PDM, SLM, Keypad, Rotary Controller.
    • 8 configurable driver switches, 8 rotary switches and MoTeC Keypad and Rotary Controller support, each with 10 positions that can be simultaneously mapped to launch control, pit switch, anti-lag, traction, race time reset, engine speed limit maximum, throttle lever translation, fuel volume trim, ignition timing, fuel mixture aim, boost limit, traction aim, and traction control range.
