After installing an MSD DIS -2 Series Ignition Control on the waste spark ignition system of a ’96 and later Saturn, the ECM of the vehicle will not be able to receive a cam sync signal. The Cam Sync Generator produces a cam sync signal after start up for the factory ECM. This is done by detecting a cylinder that is under compression through its signal wire which is wrapped around the designated spark plug wire. (On Saturn applications, the number four spark plug wire is used for the cam sync.)
Notes :
For use on vehicles with MSD DIS-2 Ignition Controller.
