Features

For racers that don't need a lot of programming options, the Digital-7 Plus Ignition is a great choice. State-of-the-art technology allow the 7 plus to produce more power while using less 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 degree 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 ignition. 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!
The Digital-7 Plus provides racers with two smooth rev limits, one for top end overrev protection and another to activate with a clutch or transbrake switch for use on the start line. Both are adjustable with rotary dials in 100 rpm increments from 2,000 -9,900 rpm with a maximum of 12,500 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 degree. Next to the rotary dials there is a LED that will verify that the ignition is receiving a trigger signal and will also warn you if there is problem with the supply voltage.
The Digital-7 Plus incorporates proficient EMI filter components to keep inputs and signals free from electrical interference. Combined with the fast microcontroller and a unique input feedback circuit, the ignition is well protected against EMI. The Digital-7 Plus can be used on 4, 6 or 8-cylinder engines and must be used with MSD HVC Pro Power Coil PN 8251, or HVC-II, PN 9261.
