Ignition Control Module: Description and Operation
CIS-EIII Control Units
The CIS-EIII system uses two separate ECUs. One for fuel control and one for ignition control. The ECUs share information from various engine
sensors and use this information, compared with information stored in their individual memories, to precisely control the fuel and ignition systems for
lower exhaust emissions, better fuel economy and better engine performance, under all operating conditions.
