Rolling anti-lag
Already moving? Rolling anti-lag helps build boost before you take off from a roll. It’s for those closed-course runs where you want the turbos ready when it’s time to go.

Build boost before you go.
You know that pause while the turbos build boost? RAL helps get boost ready before you go. Use rolling anti-lag for a rolling start, or launch control when you’re starting from a stop at a closed-course event.
$195 as an add-on when you buy your ECU tune; the tune and EK1 hardware are separate. Start with your exact calibration.
EK1 availability: eligible C7C calibrations only. 2024+ Genesis G70 excluded. Available in the United States, Canada and Australia only.
For off-road, closed-course and motorsport use only. Not for use on public roads. We are not responsible for additional wear, damage, or accelerated deterioration to turbochargers, exhaust components, or related hardware resulting from the use of modified software, increased performance, or altered operating conditions.
Rolling or from a stop
Your turbos need time to build boost. This feature helps build it before you start accelerating, so the car is ready for the run. We add it to your supported tune, with two ways to use it.
Already moving? Rolling anti-lag helps build boost before you take off from a roll. It’s for those closed-course runs where you want the turbos ready when it’s time to go.
Starting from a stop? Launch control helps build boost before you move. It gives you a way to set up the start instead of waiting for boost after you’ve already left. Your exact calibration determines what’s available.
Why add it?
If you enjoy taking your car to a closed-course event, this adds something new to the car you already like driving. You get to build boost, get set, and feel the car respond when you let it go.
The idea is simple: less waiting for the turbos when the run starts. How the car puts that down still depends on your tires, the surface, and your setup.
Fitment comes first
A model badge alone doesn’t establish compatibility. Have your vehicle details and exact ECU ID ready so the team can check your setup.
2024+ Genesis G70 is not supported. Using rolling anti-lag increases mechanical stress. Continuous use or abuse may cause mechanical failure. For off-road, closed-course and motorsport use only. Not for use on public roads. We are not responsible for additional wear, damage, or accelerated deterioration to turbochargers, exhaust components, or related hardware resulting from the use of modified software, increased performance, or altered operating conditions.
