Koso EFI meter for displaying speed and temperature values of two or one temperature and gasoline/air mixture. This instrument has large numbers, making it very easy to read all the information even at high speed. Adjustable scale: 10,000 / 15,000 / 20,000 rpm. This makes it possible to adapt the instrument to almost any type of engine. In addition to speed and temperature, the voltage is displayed and there is a clock.
