If your Coyote powered Ford was built after February 23, 2016, and you need a 2-Step rev-limiter for consistent burnouts or launches, MSD part number 87311 has you covered. When activated, the 2-Step will hold your engine at a constant RPM. This can be achieved by way of a clutch switch or push button. As soon as your activation switch or button is released, full ignition is restored and you're..

Since the new Digital 6AL Ignition uses rotary dials to adjust the rev limiter, our engineers were tasked with developing a 2-Step Rev Control that could be added to give racers the ability to switch to a low rpm limit to use on the starting line. There are two easy to read rotary dials that let you set the launch rpm in 100 rpm increments. There is an activation wire that connects to the transbra..

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..
