Video: launch control
 

I guess this is what happens when you try using launch control on an unpreped track on stock runflats at 26psi. Thought I was for sure going to slam in to that bmw!!!

Oh wow that would have really sucked!

it looks like launch control did its job...

my 1LE car did that frequently on unprepped tracks when it was stock, 2nd gear was always a poop show.

It was a no lift shift 1-2 that caused the near crash

Even after launch control, it sounded like you were spinning all through 1st gear. Was ambient temp < 55F? For the best possible times under those conditions, get through the launch with minimal (or no) wheelspin and then you can go 100% pedal probably without spinning. Then shift normally on the 1-2 shift if you're already traction limited. I suspect on the 2-3 and 3-4 shift you could use the NLS feature without much spin.

At the dragstrip, I've never had good luck with launch control. But under the right conditions on an unprepped street surface, it definitely has the ability to produce a really good launch.

I am no expert, and it's hard to tell for sure from the video, but to me it looks like you are lined up way too far left in the lane before launch. You seem to get centered again right before you shift, but the problem is you are spinning, so when you shift 1-2 the tires gain traction but since you aren't perfectly straight the sudden grip makes the back end kick out.

Make sure to line up dead center with the dark black lines as that is the stickiest part of the track. Some better tires would help too.

Bingo, OP was way out of the groove (to the left of where he should have been). Agree that you want to line up in the tire tracks, illustration below from the video, yellow arrows that I added are showing the tire tracks.

He may have been forced to the left with cones because he has street tires, to protect the ideal tracks for the drag radial folks. Happens all the time at Island Dragway.

Ok, I checked the video again and it does seem to have a cone on the right side of his lane that you can see very briefly. So it looks like some dickhead did indeed push him over to the left side and you guessed it, says Island Dragway on the sign too. When I took my Camaro to Atco in 2016, one of the Jersey guys told me that Atco was their best track, then Englishtown was 2nd, then Island was last. Sad that Island might be the only one left for you guys.

Wow yeah looks like you are right, I can see the cone in the start of the video. I have never seen that in my area (IL), so I didn't even know it was a thing! Learn something new everyday.
