LC is just a check box in the track apps. When its checked, its ready and will stay ready until the car is turned off or until its turned off through track apps. To use it just come to a complete stop, clutch in first gear, hold gas at full throttle then release clutch. You will know if its working when the engine revs to the user set rev limit (3000-4500) and stays there. Traction control must be on beacuse LC uses it. It will only work if you depress throttle completely and quickly. Ive used it maybe 10 times and it works pretty good. Some wheel hop issues as always. Correct me if Im wrong guys.
