    Hey, guys. Stephanie with AmericanMuscle.com here here with the MSD Launch Master 2-Step Rev Limiter for 1999 to 2010 V8 Mustangs. The MSD 2-step is going to be for the '99 to 2010 owners out there that are looking to create a consistent, reliable launch on the track, strip, or even on 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 2-step or a launch control or a stutter box is a simple design, but it's helpful to the performance enthusiast that wants to have more consistent performance. The 2-step will give you the ability to define your launch RPM that the device will maintain 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 you're waiting to leave. If you have an NA setup, this just makes it easier for you to dial in that perfect launch RPM where you have a smooth, consistent launch with maximum power and no wheel hop. And, of course, that's gonna lead to faster 60-foot times at the strip, or pushing you into the first corner faster, or hell, maybe you 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 2-step situation by cutting fuel, but anyone in their right mind wouldn't do it that way. It's dangerous and it's not a good way to do it. So the device will intercept the spark signal from the ECU and it will modify it, which actually leads to a misfire to hold the car at the desired launch RPM. The MSD is easy to set launch RPMs. There are two dials where the big RPM range that moves 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 also helpful for the street cars that want to use this. As far as price, the 2-step from MSD is going to cost you a little over $200. So the install here is not difficult. 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 fit harness plugged into your coil wires, mount the module, and run a ground. You need to run the wiring into the cabin and tap into the clutch switch, so you're looking at some light wiring, nothing too technical, though. Overall, this is a one-wrench install on our scale here and should take you about just an hour to complete. 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 it works by cutting spark, not fuel, for a safer rev control. You can check it out more online right here at AmericanMuscle.com.

    Consistent Holeshots. Consistent launches and quicker 60-foot times are the goal of every drag racer and now you can have both by simply installing a MSD Launch Master 2 Step Rev Limiter in your V8 Mustang.

    Easy To Set. The MSD Launch Master Rev Limiter is easy to set with two built-in rotary dials ranging from 2,000 to 11,900 rpm in 100 rpm increments. When activated the rpms will be held at the set rpm range allowing you to keep your eye on the "Christmas Tree", not the tachometer.

    Easy To Install. The MSD Launch Master 2 Step Rev Limiter connects directly to the factory coils for an easy straight forward installation and features a handy LED that shows when the launch rev limit is active.

    Application. The MSD Launch Master 2 Step Rev Limiter is designed to fit 1999 to 2010 modular V8 Mustangs with a coil-on-plug system. Including the GT, Bullitt, Mach 1, SVT Cobra and Shelby GT500 models.

    Fitment: 1999 2000 2001 2002 2003 2004 2005 2006 2007 2008 2009 2010 Details

    So after looking at the installation notes; it said that it may ruin your cats - i understand that. Someone i know who has a 2015 gt said that in order for me to buy and install this I'd have to get rid of my cats completely. Does anyone know if this is true?

    • The MSD Launch Master 2 Step Rev Limiter does not require the removal of the catalytic converters, however, since you will run the risk of damaging them, it would not be a bad idea to remove them completely. With this said, you can still use your catalytic converters, and will not affect the operation of the rev limiter module.

    I've got a 2006 GT but with the 2010 GT500 motor. Did it work on it ?

    • The MSD Launch Master 2 Step Rev Limiter (99-10 V8) will work with a 2010 GT500, or a 2006 GT. However, we can't guarantee that this will be a direct fit because the vehicle has been so heavily modified off of its original platform.

    I have a 2008 Mustang GT xan u give me a better description for the blue and the white and blue wire. I've tried every combination in wiring it to the black and white wires to my clutch pedal. None seem to work. Can someone give me a straight forward answer on how to wire this for my car directly. Spent 4 hours crammed under my dash and still doesn't work. 1 answer
    I set up everything as the instructions said to. I have a 2006 mustang gt. The blue wire is connected to the white wire off the top of the clutch switch. The red LED on the MSD two step stays on when the car is on regardless of whether I apply the clutch or not. It does not work and does not limit the revs. 1 answer

      2005-2009 Mustangs beware

      If you own a 2005-2009 mustang do not buy this product. Wiring diagram they give you is useless for your car, it will make your car run terribly , will throw an engine misfiring code, and will break with in months of buying it. Save your money and get something else.

      How to install

      Just a little FYI on the 08 mustang the only way to get this to work bc your clutch safety switch is a ground is to run a wire to the clutch switch and tie it in with the main ground on the msd and the blue wire. Took me several hours of playing with it to get it to work but after I did that it works like a charm, maybe this will take some of the headache out of it for someone.

      Wise Investment

      Super easy to install, I put a toggle switch in the center console in line with the clutch wire. Does exactly what it's intended to do. I have had it on my car for 2 years now. Will start to flood the car if you get stupid with it, just let it run for a few minutes after you're done lighting the ground on fire and you'll be good.

      Simple plug and play

      Easiest way to run the cables for 05-09 is through the rubber grommet behind the front driver's side wheel. The grommet has a nipple you can cut and pull the wires through right behind the clutch. I used the black wire coming from the clutch switch and it works flawlessly.

      2007 shelby gt 2 step

      pretty easy install overall, everything is a plug and play other then running your power wire through the fire wall and then tapping it into the power wire above the clutch on the clutch switch, took about an hour to install. and of course your not getting any more power but it does help with launch control big time and when you go driving around colleges at night to scare the girls with the nasty 2 step pop and flames.
