Launch control trouble

blank · 06-02-2015, 01:00 AM

I haven't had any luck getting it to work. I was at the dragstrip this weekend and tried it 3 times in a row with no success. My poor car

i beat it up.

I followed the instructions in the manual and the the flag comes up and everything, but as soon as I lift my foot off the brake, the car lurches forward and then cuts the power. If I lift my foot off the accelerator and then back on, then I start moving again. It was rather embarrassing to just stop when the tree turned green on the track.

I was able to hold the brake and build up revs without doing "launch control" where the little flag does not show up. Does this do the same thing? Has anyone else heard of this power cuttoff when doing launch control? I saw one person mentioned it might be the eLSD in another post.

I would imagine the DSC was off too? if not it will cut the power when you lift due to wheel spin.

Do you have good tires in good condition?
