Now, the clutch release is critical with manual transmission vehicles. Depress the clutch fully and hold it. Activate the launch control switch, which engages the RPM limiter. Bring the engine to the pre-set RPM, feeling the car ready to explode. Once the green light (or your signal) hits, release the clutch smoothly and quickly. Don't dump the clutch; a smooth release is key to minimizing wheelspin. Simultaneously, apply full throttle. The engine should hit the set RPM, and the car should launch aggressively. You want to aim for a balance: enough RPM to build boost (if you have a turbo or supercharger) but not so much that you spin the tires. Watch the tachometer to ensure the engine is holding the launch RPM until you release the clutch. With an automatic transmission, it is very similar. Hold the brake and push the accelerator until you reach the launch RPM set on the 2-Step unit. Release the brake, and the car will launch. Monitor wheelspin and adjust the launch RPM accordingly. In the real world, you might need to adjust based on track conditions. On a sticky track, you might be able to use a higher launch RPM. On a slick track, reduce the launch RPM to prevent wheelspin. Pay attention to how the car feels. You should feel the car squatting and transferring weight to the rear wheels. If you feel excessive wheelspin, lower the launch RPM. If the car bogs down, increase the launch RPM. Data logging is super important here. Use a data logger to track your launches and analyze your performance. This can help you fine-tune your launch technique and settings. Practice, practice, practice. Consistent practice is essential. Experiment with different launch RPM settings and clutch release techniques to find what works best for your car. Finally, remember that safety always comes first.
