LPG/CNG Controller

TECH-300 OBD Series

TECH-300 OBD is a series of microprocessor controllers with a traditional 56-pin harness. Controllers in this series are designed for engines with a maximum of 4/6/8 cylinders (depending on the version); it is also possible to connect two controllers in parallel, allowing gas supply control in 10/12/14/16 cylinder engines. The compact casing with small dimensions of 190x125x30 mm allows the controller to be installed in hard-to-reach places.

  • Supports gas injection for up to 8 cylinders – depending on the controller version
  • Intelligent automatic error clearing
  • Automatic real-time LPG/CNG gas injection timing corrections based on parameters read from the gasoline ECU’s OBD bus
  • Data logging for mapping during driving without PC connection
  • OBD Scanner function – allows reading basic diagnostic data, settings, and reading/clearing OBD errors
  • Supports CAN protocols (11/500; 29/500; 11/250; 29/500), ISO 14230 slow, ISO 14230 fast, ISO 9141 using the same wires
  • Corrections for gas temperature, reducer, gas pressure, and engine RPM
  • Tuning in STANDARD and TECH modes (innovative control algorithm with auto-calibration and auto-adaptation systems)
  • Self-diagnosis, error detection, and installation fault detection
  • Full short-circuit and overload protection
  • Support for Valvetronic and Wankel engines
  • 56-pin connector
  • Aluminum casing
