GoFast is a versatile controller designed for installation in most cars (sequential, semi-sequential, “full group”).
The device has been designed as simple as possible the entire system, and a significant shortening of the time needed for installation and calibration of the system. Created controller is based on a 32-bit processor and components of automotive, which proves its modern design and reliability.

GoFast benefits
•    fast installation due to the minimal number of wires,
•    Simple and clear calibration program - only two dialog window,
•     processor has the ability to expand with new software features,
•    application sessions without the controller in use demo mode,
•    small  - compact weather - resistant housing,
•    a switch with an integrated buzzer  – only 3 wires are required for connection.

Simple installation
The controller is an extremely installer-friendly device the minimize number of wires, required to connect the controller and contributes to reduced installation time.

  • no connection cable to the reading of rotation, the controller calculates them based on the time of injection
  • in most case it is not necessary to connect the ignition signal
  • a switch with an integrated buzzer  – only 3 wires are required for connection
  • gas level indicator CES (H) is powered directly from the solenoid valve mounted on the cylinder.

Simple calibration:

  • all functions are arranged on two panels and no tab switching is required,
  • build-in standard and expert  function. Mode of standard contains the minimum functions necessary that to set up the car. However, at any moment by pressing the switch to expert where the advanced more functions of the controller,

  • support of controller too with Bluetooth Next.


  • new hardware platform based on a 32-bit processor,
  • fail-safety – use the components of automotive,
  • optional extension with new application features,
  • application sessions without the controller in use demo mode.

Application functions:
•    preview of working parameters on the oscilloscope,
•    petrol injection time map 2D,
•    the fuel LPG / CNG,
•    engine RPM signal filter,
•    operation with various types of injection control (standard, doubling),
