Gotech MFI

Gotech MFIThe GOTECH MFI system was designed to provide a low cost, easy to use micro-controlled engine management system. The system is fully adaptable to suit engines from two cylinders up to six cylinders. It provides easy tune-ability for both normally aspirated and turbo-charged engines using electronic type fuel injectors.
GOTECH MFI provides two distinct yet integrated systems namely the ignition control and the fuel injection control.

Gotech MFI Information and Features

Ignition Control

  • Full control over ignition timing at preset RPM intervals and 32 load intervals
  • Interpolation between load points for smooth timing transition.
  • Ignition control input provided by engine speed and manifold pressure. (Software mixable)
  • A soft touch rev limiter is provided to prevent dangerously high RPM to be exceeded.
  • Progressive 3-stage gearshift RPM warning lights provided to remind driver to shift up.
  • Ignition is fully configurable using serial link to P.C. or laptop. (Usb link provided as optional)
  • SOF-TECH 2D software provided for easy tuning. (Windows)
  • Timing Configuration up to 12 000 rpm. (16 000 RPM in near future)

Fuel Injection

  • Staged Fuel Map
  • Full control over electronic injector time at preset RPM steps and 32 load sites.
  • Interpolation between load points for smooth transition.
  • Able to drive 4 X 2 or up to 8 X 16 injectors.
  • Many Sensor Inputs
  • Manifold pressure.
  • Intake air temperature.
  • Throttle position.
  • Engine liquid temperature.
  • Engine speed.
  • Lambda (Closed loop lambda control)
    • Rev limiter cuts fuel supply to prevent over-fuelling.
    • Fuel injector time mapped at 500 RPM intervals from start-up to 12 000 RPM.
    • Mixture adjustable from inside cockpit to enable setting up of map.
    • Injector time is fully configurable using a P.C. or laptop using Fuel Management Software.
    • Closed loop lambda control (Exhaust O2 content) monitoring through Fuel Management Software.

Additional Features
