In this video, I present to you a topic that raises many questions among participants in groups and forums related to the Fiat line: The Magneti Marelli Microplex ignition system, used in the Fiat Uno Mille from 1993 to 1995 and in the Fiat Fiorino 1.0 8V in the same period, especially with the very common mistake of people interpreting this system as if it were an electronic injection, which ends up distorting the information of many people. In these minutes, there is an explanation regarding the operation of this system that combined a double-barrel carburetor and a module responsible for all ignition control, in addition to the pros and cons of this system adopted, at that time, by Fiat. Topics covered in the video: Changes in legislation aimed at pollutant emissions for motor vehicles in the 90s; The arrival of 1.0 vehicles in the national market and Fiat's strategy with its Uno Mille model; Magneti Marelli Microplex ignition system (Mille Electronic/ELX): Operation and arrangement of parts that make up the system; Location of sensors and actuators in this ignition system; Connection points between the Microplex and the Ecobox system used in these vehicles; Wiring diagram and wiring harness for the ignition modules and sensor controller.
