Hi guys, I picked up an 08 SS about a month ago. I never got an owner's manual supplement on the no-lift-shift instructions. Obviously you have to shift quickly with your right foot on the floor, but does the supplement give any more details?

1. Does in work in any gear (except fifth obviously)?
2. Is there a minimum RPM for it to work, or do you have to run it all the way to the red line?
3. Do you have to be in Competition Mode or does is it always active when you're flooring it?

I've successfully shifted with it floored from 2nd to 3rd (at red line) a few times, but I don't know if the no-lift shift actually kicked in. I tried listening to a pop out the exhaust, but there's too much wind noise to really hear it.

Also, I know competition mode turns off the traction control and enables launch control, but does it do anything else such as change the stability control or throttle response?

Thanks.

Thanks, but that doesn't answer my questions.

 

theres only supposed to be one pop from 2nd to 3rd

 

1.) you don't have to be in competition mode

2.) I only hear the pop on the 2-3 shift

3.) I think you are supposed to do "traditional" shifts after 3rd...

4.) it seems to work beginning around 5700rpm-6000(rev limiter) so you don't have MUCH time to do it and in your shifts, you have to be fast... its best to when driving normal, get used to shifting really fast before you try it @ wot that high in the revs... I know I missed it more than once starting out, lol

 

I tried a no-lift shift this morning from 2nd to 3rd just before 6 kRPM. I completed the shift, but I don't think the computer actually retarded the timing because it still started shooting up to the redline. It didn't bounce off the limiter because I was in 3rd before it got there. Shouldn't the RPMs hold for a split second and then drop as soon as you engage the clutch in the next gear. I don't understand what I'm doing wrong. Maybe it has to be at 6 kRPM or more...

 

theres a supplement to your owners manual that tells you what to do and how to do it...

if you didnt get it, get one from your dealer....

this is the 75987349587495874987th thread on this question!...

youd be surprised how many people havent read this and are using/doing it wrong....

"from a stop"...are some of the first words in the supplement...

 

I know there is a supplement, which should have been obvious from the OP. I called the dealer the day after I got the car and asked about the supplement. They said they never saw it and had no idea what I was talking about. I thought already understood how to do it, so I told them I probably don't need the supplement, but I guess I do.

Even though this is the 75987349587495874987th thread on this question, no one has ever posted exactly what the supplement says. Instead, all I've seen is rumors and guesses. Is it too much to ask that someone to provide exactly what the supplement says here so I don't have to hassle with the dealer? I would appreciate it greatly.

 

I called chevy, they said there's no supplement. If someone actually has a supplement, can you PLEASE tell me what it says. Or, even post a scan/picture of it. Please........

 

No-lift should be done as close to redline as possible, and you do not need to be in comp-mode to do it. Car gives you .2-.3 seconds to complete the shift, so it may take a few tries before you get it down.

As for comp mode itself, other than what you noted, I believe it backs off the stability control, but definitely does not disable it. If you want to turn everything off (not advisable), hold the button down for 10 seconds. DIC will flash "ESC OFF". Only time I used this was on a dyno, as the car systems were going haywire with the fronts rolling free and the rears still.

 

You need to start the shift (clutch pedal going to the floor) right before redline. Or in other words time it so that around 6200 rpms you're shifting before you hit the 6300 soft touch rev limiter. If you do it really quick and time it just right you may not even hear a "pop" which is caused when the engine is limiting and holding the revs at redline. I've seen people posting they were trying it at ~5500-6000 rpm and that would be way too soon and explain why it wasn't working too well for them. If you're going to short shift (shift early) you need to do a conventional shift. As mentioned it works in all ETC/ESC modes, on or off, and at the track I've used it for the 3 to 4 upshift a couple times. I think by the time you hit the 4th to 5th gear change you can spare that .07 second improvement no-lift offers.

 

Thanks.

I know it should be as close to the red line as possible, but I would rather be watching the road instead of staring down the tach when I'm shifting. I have to think there is a window in which it works. I wish I knew exactly how big that window is. Does the supplement say?

Yeah, the 4th to 5th shift doesn't really need it.

 

as far as i know itt only works in comp mode ive tried it a few times without it on and failed so i dunno

 

Bump. Does anyone actually have the manual supplement? I tried the 1st to 2nd shift a few times and just can't get it to go into gear. I'm getting really frustrated.

 

I dont own one but i have a business partner who does and i drove it once in competition mode and took off from a stand still and i had no problem with the no lift shift at all... i think you need a driver mod or something....

 

you most definitely DO NOT have to be in competition mode

 

This is when adjustable shift light comes into play. Comp mode only turns TC off and increase ESC's yaw limit tolerance.

Everything is in your manual. Read it.

 

That's the thing. I don't have the manual supplement and the instructions are not in the generic owner's manual. I've been begging and pleading for someone to tell me what it says. Do you have the supplement?

 

why the hell would you no lift shift if you arnt going to redline the car this is the dumbest question ever and has been asked 120392183094810249821 times

 

Until your traction control notices the wheel spin and kills power and applies the ABS to stop it... So yes, you do need it on to prevent that. Or traction control and ESC turned completely off, and no-lift only applies to the 1-2 shift.

 

How do you know that it only applies to the 1-2 shift? Does it say that in the owner's manual supplement?

 

No, but just personal observation (so I may be way off base). You can tell a difference between the 1-2 and 2-3 shifts, it feels like the 2-3 and 3-4 is just a normal power shift.

 

ive played with it a lil over the past month and have got mine to pop once a couple times from 1-2 and 2-3. it took me a while to get it right. i can only do it on a straight when i have time to glance down at the tach. i found that if right around 6000-6100 rpm you push the cluth in (further than normal it seems...normally it seems like i dont have to push it very far but for this i have to make sure i push it in a lil further otherwise it kinda locks you out of the next gear) but anyway as soon as you get the clutch in your rpms should have moved to about 6200-6300 since you didnt let off the gas. As soon as you get the clutch in you should be shifting as fast as you can and letting back out. So in short clutch goes in at around 6100 and with the gas still in you need to have the clutch back out by the time you hit 6300. Mine pops every time if I can hit right.

 

thats weird because on my car it works perfect from 1-2 gear.

This guy does not know what hes talking about! you can no lift in every gear!

 

QFT i nls 1.2.3. every time no matter what gear you should hear a pop..The reason you should be in comp mode is so if you chirp tires it dosent bog you down to decrease your wheel hop.if your tires are hot this dosent really matter..

when 1st trying this i recommend practicing the 3-4 shift because you have more time to prepare, and its a straight down shift wich will make it easier also there wont be any wheel hop there either this will allow you to get t right before trying a harder gear..Shoot for the gap between 6000 rpm and the redline i feel like this is the best spot to nls. On a final note, i dont know why ppl say "dont nls after 1st just regular shift" The car was ment to nls all gears...ive never done 1 from 4th to 5th simply because ive ran the car 4 passes at the track, and never left 4th gear
