The TECH-300 controller series consists of microprocessor controllers in aluminum housing with traditional 56-pin wiring harness. Controllers in this series are designed for engines with up to 8 cylinders, depending on the version. Parallel connection of two controllers is also possible, enabling gas flow control in engines with up to 16 cylinders. Compact housing with small dimensions – 190x125x30 mm allows for controller installation in hard-to-reach locations.
