ICM200 SERIES - Fuel and Ignition Management System (FIMS)

The Ignition Control Module (ICM) 200-series is an intelligent electronic control module which is part of GAC’s distributor-less ignition system. The ICM triggers an inductive coil by charging the coil with the appropriate amount of energy for high voltage induction into the engines’ spark plugs.



Capable of up to 8 cylinders sequential or 16 cylinders wasted-spark
High-energy inductive ignition system
Supports camshaft / crankshaft engine position sensors of either the Hall Effect or variable reluctance type
Fixed timing with in-field global trim capability as well as two variable timing maps based on engine speed and load
