I currently have the MSD DIS-II installed on my 2002 Z24 and I'm going to be installing the GM SC in a few days. Will the basic settings for the MSD be fine, or do I need to retard the timing or remove it? Or change the RPM that the three sparks stops at?
Also, is it possible to run a smaller pulley on the GM reflash? All of the time?
Don't retard any timing with the DIS-2. The GM Reflash will do that for you.
Leave your DIS-2 the way it is now.
