I turned it off when i got on the track and since my car was left on it never turned back on till i left the track later that day i hit the button and turned it on..when ur about to make ur run just hit the button..i don't use the TC if im racing or at the track i just turn it off. TC Is definetly ur enemy when it comes to launching and on the track when it rains and its slippery its ur friend. If you want to permanetly disable it . Just pull the fuse its # 46.
