Digital 7 Plus Ignition Control,
PN 7520
|
For drag racers, the MSD 7AL-2 has long been the standard ignition due to its reliability and power. By combining the 7AL-2's high performance with the proven digital technology from the Digital-6 Plus Ignition, MSD once again raised the performance ignition standards by introducing the Digital-7 Plus Ignition Control. State-of-the-art technology allows the 7 Plus to produce more power while using the same amount of current. The CD circuits combined with an IGBT Coil driver deliver 520 - 535 volts to the primary side of the coil with up to 190 millijoules of energy at any rpm. Below 3,300 there is of course MSD's powerful series of multiple sparks, rather than a single spark. This spark series burns in the cylinder for over 20° of crankshaft rotation resulting in improved combustion and increased power. Inside the familiar gold housing is a 15 Megahertz microcontroller, the fastest of any digital ignitions. This means that the controller analyzes up to 15,000,000 critical instructions per second to produce the most accurate timing control and rev limits possible! There are two smooth rev limits, one for top end overrev protection and another for a launch rpm. For nitrous applications or for racers looking for a little more mph, there is a high speed retard circuit that is adjustable up to 9.9°. These features are adjustable with rotary dials plus there is a diagnostic LED. The Digital-7 Plus can be used on 4, 6 or 8-cylinder engines and should be used with an MSD HVC Coil (PN 8251or PN 8261).
