 By the mid-1980s, JECS were using LH-Jetronic, and the new Bosch hotwire mass airflow meter.The early JECS LH-Jetronic systems were based on a Motorola 6800 architecture, using many Hitachi components.The earliest hotwire meters were still from Germany, but by the end of the 1980s all of the system components (pumps, sensors, injectors, ECU) were being made in Japan.
