ok so ive figured out as well that if your In manual mode and are in sport handling mode you can pull up to the lights pull and hold both paddles get race start pull right paddle to confirm (all this with your foot on the brake) that there is no time limit to push throttle.so you can wait for quit a long time for the light to change before you hammer the gas to get it to rev before you launch.Basically what i am saying is you dont have to stop and fumble around pushing buttons while watching the lights to get the race start set up.
OH YEAH, it works great and it is AWESOME! Nothing like being put back in your seat by a little four cylinder..
