      Video Review & Installation

      Stephanie: Hey, guys. Stephanie with here with the MSD Launch Master 2 Step Rev Limiter for 2011 to 2014 GT Mustangs. In this video, we're going to talk about the functionality of this two-step module and the install, as well. I'll go over the install in a little more detail later, but I can tell you right now that I'm going to call it a one out of three wrenches on the difficulty meter. The MSD 2 Step is gonna be for the '11 to '14 GT owners out there that are looking to create a consistent, reliable launch on the track, strip, or even the street. This launch control connects to the factory coils. And it works by cutting spark, not fuel. So it's a good option for anyone looking for a safe and effective launch control for their Mustang. A two-step, or launch control, or stutter box, whatever you want to call it, is a simple design, but it's helpful to the performance enthusiast that wants to have more consistent performance.The two-step will give you the ability to find your launch RPM. And the device will maintain it for you. This allows you to hold the car at full throttle while preparing to leave the line, so you don't have to worry about manually holding your launch RPM and watching the tree at the same time. If you have a forced induction setup, this allows you to build boost while waiting to leave. And if you have an NA setup, this just makes it easier for you to dial in the perfect launch RPM where you have a smooth, consistent launch with maximum power and no wheel hop. And, of course, that leads to faster 60-foot times at the street or pushing you into the first corner faster or, hell, maybe you guys just want to have fun on the street.The MSD 2 Step works by cutting spark, not fuel, which is what you want. It is possible to induce a two-step situation by cutting fuel, but anyone in their right mind wouldn't do it that way. It's dangerous and not a good way to do it. So that's why MSD does it through cutting spark. So the device will intercept the spark signal from the ECU. And it will modify it, which actually creates a misfire that will hold the car at the desired launch RPM. The MSD is easy to set launch RPMs. There are two dials with a big RPM range that move in 100-RPM increments. So you can really set your launch RPM where the car performs the best. The other nice thing about this is that it has an LED that will show you when the launch control is active, which is not only helpful on the line, but it's helpful for the street cars that want to use this, too. As far as price, the 2 Step from MSD is going to cost you right in between $200 and $250. So the install here is not difficult. Overall, this is a one wrench install on our scale. It should take just about an hour to complete. You do have a little bit of room to determine how you want to wire this in. But the general idea is to get your direct bit harness plugged into your coil wires, mount the module, and run a grab liner. You will need to run wiring into the cabin and tap into the clutch switch. So you are looking at some light wiring, but nothing too technical. Wrapping things up here, the MSD Launch Master 2 Step Rev Limiter offers a great way to improve launches. It's easy to install and works by cutting spark and not fuel for safe rev control. You can check it out more online right here at
