LPG/CNG Controller

TECH-300 OBD Series

The TECH 300 OBD series features 56-pin microprocessor controllers equipped with OBD communication. This functionality enables quick and accurate mixture calibration and provides access to vehicle diagnostics directly through the LPG system. Controllers in this series are available for 4-, 6- and 8-cylinder engines (depending on version). Two controllers can also be connected in parallel to control gas injection in engines with 10 to 16 cylinders. Compact housing (190 × 125 × 30 mm) allows installation in confined spaces.

  • 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
