7-Series AL Ignition Controls
From NHRA to Circle Track, it'll make you a winner...
MSD 7AL-2 Plus features a built in two-step rev control and diagnostic LED. This ignition delivers full power at any RPM. Multiple-spark discharge circuitry improves throttle response, off-corner performance, idle, and launch consistency. Built-in, soft touch rev control protects the engine from over-rev damage. The 7AL-2 Plus' accurate rev-limiting action is smooth without backfires. Adjustments are easily made with plug-in modules, and the ignition can be triggered from points, magnetic pickups, crank triggers, and electronic amplifiers.
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.
It says in the description that this box has an ignition adjustment when starting, but I don't see in the instructions where it is wired. Is it internal and if so, 10 degrees?
Does it have to be ran with a computer?
WARNING: Motor vehicles contain fuel, oils and fluids, battery posts, terminals and related accessories which contain lead and lead compounds and other chemicals known to the State of California to cause cancer, birth defects and other reproductive harm. These chemicals are found in vehicles, vehicle parts and accessories, both new and as replacements. When being serviced, these vehicles generate used oil, waste fluids, grease, fumes and particulates, all known to the State of California to cause cancer, birth defects, and reproductive harm.
WARNING: Some dust created by power sanding, sawing, grinding, drilling, and other construction activities contains chemicals known to the State of California to cause cancer and birth defects or other reproductive harm. Some examples of these chemicals are: lead from lead-based paints, crystalline silica from bricks and cement and other masonry products, and arsenic and chromium from chemically treated lumber. Your risk from exposure to these chemicals varies, depending on how often you do this type of work. To reduce your exposure, work in a well-ventilated area and with approved safety equipment, such as dust masks that are specially designed to filter out microscopic particles.
