With MSD's race winning experience and performance ignition knowledge, the Programmable Digital-7 is THE ignition control.

No Timing Compromises
Ignition timing is always a compromise between cylinders. The dynamics of the flow of air and fuel into each cylinder is never exactly the same no matter how much machining magic has been done. This has always caused top engine builders to compromise their ignition timing. With the Programmable Digital-7's advanced Individual Cylinder Management system and other exact timing programs you will never need to compromise again.
