Hey all, so finally made it out to a 1/4mi track to see what I could run and only got one pass in and was kind of disappointed.

60'...2.61
330...6.44
1/8...9.38
1/4...13.9@107.39

Whats the best combination as far as rpm's on stock tires for a good launch? I'm thinking that the 5k limited on launch control is a bad idea because it will either wheel hop like a champ or spin. Any input would be appreciated. *this run I left the line easing into first and second until about 2,500 rpms then slowly laid into it and still spun a bit until around 4,300rpms*

 

I launched at 2500 on the stock tires with them at about 23psi. Launch control=fail. at least in my book. I run with ESC off. Got a 13.9 that way at 103. Minimal spinnage and NLS 1-2 and 2-3. Dunno how gms1 is but thats how i did it 100% stock

 

I went from idle on stock tires. You have a lot of time to pick up in that 60ft. I can see you going into mid 13's easy.

 

Launch control= win with the new adjustable launch control Trifecta just came out with.

 

what shib said about the 60ft too. mine are about 2.18- 2.21 and theres still room for improvement.

 

Not on stock tires

 

The boost control feature is good for stock tires

 

Im thinking just a track day and trying different configs is best. Maybe 25-28psi in tires, and trying to launch at 500rpm intervals to figure out whats best. Shib, think easing out of 1st n 2nd is best or just let it spin in 2nd til it catches?

 

If thats what you think, so be it. May have been true before you could adjust it, not anymore.

 

Lots of seat time and runs help a lot. Im at like 20+ runs in the cobalt alone lol. I would advise against letting it spin. Gotta find that edge of full grip and almost spinning

 

Spinning is better then hopping though, Hop=broke ****.

 

Yeah you gotta get that 60ft down. I'm down to a 2.0 consistently with my nitto invos

 

Truths. I've never had hop though. If i ever do, instantly off the gas.

 

i havnt been back to the track yet with the new launch control feature but my avg 60ft is 2.4 lol
should be a lot better with the new lc setting!
im shoting for high 12's...best so far is a 13.2 on nitto neo gens with 26psi in tires
trifecta tuned to 23psi...and full bolt ons cept 3in exhaust

 

is the new lc setting an external controller?

 

Your car has more potential. Based upon your trap speed I could see you running low- mid 13s with a good launch.

 

best I've seen with my stock tires and current mods are 13.3, wanted to adjust tire PSI but didn't make it to the track in time, most I saw was 24 PSI while running using NLS

 

Have anyone had the boost reduction done to their first gear in your tune?

 

when did u get a 13.2!? best i saw was a 13.5

 

no its a new feature in trifecta tuning...the launch control can be adjusted accordingly through your tune.....

kyle: you know nothing

 

Is it really better to hack up the ecu controller over installing a 2-step wot box? just saying... the wot box will allow you to piggy back an rpm controlled trigger like nitrous, or methanol, or cry02 setup, etc etc. Is there some reason were all hellbent on using the default ecu to launch control?

 

oooooo. busted!!

 

busted is right!! i wanna see this hight 12 at the bash

 

not bent over it, for me it not wanting to spend the money on something my car comes stock with....

12.9 at the bash!

 

then ill do the same if not better
