Running redundant ignition systems gives you piece of mind during long races, but how do you swap the coil wire to the back up ignition? The MSD Automatic Coil Selector solves this problem. The Coil Selector has two posts that connect to the high voltage coil towers of the ignition coils while a third post connects to the distributor cap. When a racer switches from their primary ignition to the b..
The user can then select between twelve different rpm limits by simply turning the knob. Six models are available to cover a range from 3,000 rpm to 12,800 rpm in 200 rpm increments.BrandMSDEmission Code5Part Number8670..

To help drag racers achieve even more consistency, our engineers have incorporated an adjustable low rpm stage into a Three Step Module Selector! This allows you to make adjustments in 100 rpm increments from the driver's seat! The Launch Control Module features a shielded harness for increased protection against EMI so it can be mounted within easy reach of the driver. This way, as track conditio..
As an example, we'll use a drag car with a Three Step Module Selector plugged into the rpm socket of a 7AL-2 Ignition. The different rpm modules are activated when 12 volts are applied to a corresponding wire. By connecting one wire to the line-lock circuit, one module will be activated during the burnout. This helps keep tire temperatures consistent. When the line-lock button is released, the li..
