In this article we are going to analyze JECS in detail, a topic that has gained relevance in recent times. It is important to understand the importance of JECS in various spheres of daily life, since its influence is considerable in aspects such as health, economics, politics, technology and culture. Along these lines we will explore the different facets of JECS, as well as its implications in today's world. From its origin to its possible future developments, we will delve into an exhaustive analysis that will allow us to better understand the role that JECS plays in the contemporary world.
JECS Corporation (formerly Japan Electrical Control Systems Co Ltd) is an automotive components company headquartered in Isesaki, Gunma, Japan and a wholly owned subsidiary of Hitachi. Its principal products are electronic control units, software, semiconductors, mechatronics, resin molding, inspection technology and material analysis.
JECS was formed in June 1973. It was a joint venture between Robert Bosch GmbH, Nissan Motor Co. and Diesel Kiki Co., Ltd.. It enabled Nissan to use Bosch's engine control technology, and gave Bosch access to the Japanese market. JECS later expanded to manufacture many other automotive parts besides EFI systems.
Unisia JECS sponsored the Hasemi Motorsport team in JTCC and JGTC from 1991 until 2002. The Unisia JECS Skylines (GT500) and Silvias (GT300) also featured in video games & toys.
16-bit ECUs from JECS were produced for the 1993+ Nissan 300ZX.
Bosch first produced the Jetronic EFI system in 1967. K-Jetronic & L-Jetronic followed from around 1973 which is when Nissan became involved.
Early JECS systems were L-Jetronic, with Bosch moving vane airflow meters. These systems used a mixture of German & Japanese parts. The electronics were Japanese, the sensors often German, the fuel pumps/regulators made under license to Bosch by DENSO.
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.
