The goal is to make good power, improve the off-boost power and make sure the mixture is ignited well at high RPM and boost  |
The MSD ignition systems will improve engine performance of the 930 over the stock CDI in two ways. One, below 3000 rpm it fires the plugs twice for each combustion cycle thus keeping the plugs clean. Two, they give added control of timing. Depending on which controller is installed, various levels of control of timing are available.
The MSD with controller modules facilitate greater initial timing which helps wake up low rpm performance then facilitates retard of timing at higher rpm and boost (to prevent detonation and destruction).
MSD ignition systems arranged from greatest to least control:
MSD 6AL Ignition with MSD 8977 Controller
MSD 6AL Ignition with MSD 8762 Controller
MSD 6462 Integrated Ignition and Controller
MSD 6AL Ignition
The below listed MSD parts and links should be studied to determine which system will best suit your needs:
