Second, it is programmable with MSD’s Pro Data-software, allowing custom timing adjustments, nitrous boost, and shift light activations, and even programmable rpm/time rev-limiting maps. That will allow it to support engines even up to 2,000 horsepower. This MSD Programmable Digital 7 Box has a number of upgrades that racers of all kinds – from Drag to Circle Track, want and need in a race box.įirst, it features over 30% more spark energy, 190 millijoules per spark, than the 6-box. At 1,100 hp, it’s combustion process features a whole bunch more air and fuel than a street car would have – and you need a correctly matched ignition to burn that mixture. Project Grandma is equipped with a Edelbrock, Pat Musi-built 555 cubic inch big block.
With 135 millijoules of spark output, it’s great for serious street cars – but you’ll REALLY want something serioues – like this MSD Digital 7 – for a RACE CAR. It’s a digitally-controlled ignition that can produce up to 535 volts, has the multi-spark functions, and a built-in rev limiter and 2-step. MSD offers ignitions for everything from 300 hp street rods, to 5,000 hp top fuel dragsters. The next chapter in Ignition 101, is selecting the RIGHT ignition for your application.

Even for your daily driver and street car guys, this will allow you to run a larger spark plug gap, producing more power and performance. These high powered sparks ensure complete combustion of the fuel mixture at everything from idle to high racing RPM, producing more power. This is because MSD uses Capacitive discharge technology to produce a very high primary voltage. Now let’s discuss what MSD calls Capacitive Discharge.Įach spark an MSD ignition produces is an extremely high current spark. MSD’s ignition boxes feature Multiple Sparks at lower RPMS, along with a stronger, hotter, higher voltage spark to completely ignite the mixture. When you begin to make performance upgrades to your engine, including free-flowing induction and exhaust, more air and fuel is required to maintain the correct air/fuel ratio. Enough for a totally stock engine, but not optimized for performance. As you can see here, the stock ignition produces a single, weaker spark. With a stock ignition system, one small spark is all that is necessary to combust the mixture of oxygen & fuel in the cylinder. Let’s explain how an Multi-Spark Ignition works. Do not connect these.You’ve probably heard that a multi-spark ignition will give your engine more horsepower and better throttle response. With the MSD ignition box, we do not use the VR sensor wires (orange and violet).
the coil negative (-) wire is thin black,.advance control signal is a white wire,.tach signal is a yellow wire (do not use this to feed to pin #24 on MegaSquirt ® EFI Controller, it is for a tachometer only),.With a MSD modules, the ignition module wires you need to know about are: Rev limiter connections 4, 6, 8 cylinders even fire only There were a number of different kinds of MSD 6A modules: The MSD 6A ignition is a popular aftermarket capacitive discharge, multiple spark ignition controller.
