Not a signal bender!

Pretty much every aftermarket ‘Tuning' solution for the GR Yaris, is just a signal bender or 'interceptor'

This means that you are taking the factory sensor signals, and manipulating them so the ECU does something different based on false information.

This can be potentially dangerous, or in some cases pointless, as modern ECU's 'Learn' and can simply reverse the changes that you have made over time.

The Powertune Yaris Plugin kit doesn't manipulate the factory sensors to 'trick' the ECU, but rather provides you with a platform for complete Engine control.

The kit completely removes the factory ECU, and replaces it with a MoTeC M141 ECU, making it a complete Plug and Play system.

This means that you can easily change things such as Turbo, Injectors, Fuel Pumps and Camshafts; and still be in control over what the engine is doing.

With all aspects of the ECU tuneable, this means that you have complete control over things such as:

  • Fuelling
  • Ignition Timing
  • Injection Timing
  • Injection Blending (Primary/Secondary Injectors)
  • Boost
  • Inlet and Exhaust Camshaft Position
  • Individual Cylinder Fuel/Ignition Trimming
  • Many More

Additional Functions that are added with the M1 Plugin.

  • Launch Control
  • Anti-Lag
  • Race Traction Control
  • Nitrous Control
  • Water Methanol Injection
  • Rolling Launch Control
  • Ghost Cam
  • Mappable Boost, Throttle Mapping, Mixture Aim, Ignition Timing Maps via Drive Mode Switch
  • Closed Loop Lambda Control
  • Inbuilt Data Logging
  • Knock Control
  • Support for additional sensors for logging or other operations
  • Many More

Factory Yaris Functions that are supported with the M1 Plugin.

  • Cruise Control
  • iMT Throttle Blipping
  • Factory Cluster Operation
  • Factory HUD Operation
  • Factory AWD Control
  • LIN Controlled Alternator
  • Drive Mode Switching
  • Factory Air Conditioning System

Factory Yaris Functions that are NOT supported with the M1 Plugin.

  • Lane Tracing Assist
  • Pre-Collision Braking System
  • Radar Cruise Control (Normal Cruise is OK)

Whilst the dash warning lights are not illuminated for these errors, these systems will not function.

We will be adding additional features and functionality to this kit over time also.

- M141 ECU
