Well this is their webpage where you can purchase it.

It has two functions, a 2-step launch control and a No-Lift Shift feature.
You can buy each function separate or purchase both for a discounted price.
The No-Lift Shift feature turns your ignition off every time you change gear, this means you can keep your foot down on the acceleration pedal when you change gear. When the ignition comes back on I am 100% sure that it
will backfire. So a handy thing if you want to show off to your mates. But jokes aside, the main reason is to stay in your turbo boost.
The 2-step launch control sets your revs before you set off. This allows your turbo boost to kick in, when you set off you have the turbo to give you an extra push.
Don't trust me on this though, It's only my analysis after doing some research lol. It may be something completely different.
