Works every time

 

You guys are acting like a bunch of damn women. SS/TC isn't the end all of cars. I now own one and understand it's still a cobalt just a slightly better one than the previous SS.

SS/SC and SS/TC are both great cars. Both have draw backs.

As for the NLS in the TC. My ***** have not grown enough to try one yet.

 

I personally don't worry about it, but I also make sure my tires aren't spinning in first before kicking it into second since that's a good way to destroy your clutch and tranny in a hurry .

No matter how you time it the chances of it being "smooth" are slim to none, espeically with first gear being so short. If you're concerned with the jerk then perform a traditional shift to put your mind at ease, if not, the shift isn't bad for the car and should be consistent with USMCFieldMP's video. If it's incredibly violent chances are you're doing something wrong and should correct it before you damage your vehicle or something of that nature. I'm wondering if in the OP's case he he pulling the car out of gear before the clutch is totally disengaged resulting in the car lurching...I've found timing on gear shifts with the low low disengagement point of the clutch on the TC can be tricky and this would definitely lead to a violent shift.

Permafried-

 

Nope ....they didn't have to . Our boost is instant.

 

Do you really think our little turbos have a lot of lag? Even if you do not use the NLS it takes very little time to spool up after you lift to shift.

 

True the spool is pretty damn fast.

 

Ok i chose not to read through 4 pages of ss/sc tc bitching and whatever lol.

I have not tried NLS'ing from 1-2 yet but did 2-3 3-4 like 100 times. Our turbos spool very quickly but none the less the NLS makes for a much speedier more efficient shift over normal shifting. I find myself doing it instictively when racing and those are the points in which you really can start to pull ahead more. I havn't dont a 1-2 shift yet because from a dig i get NO traction in 1st at all, so im at redline spinning tires going 10 miles an hour lol. i usually pop it into 2nd with a regular shift and then its at a low RPM in 2nd and it takes a second for me to build that boost and start pullin. I know for me thats the 1 thing i really gotta get out and practice are my launches. I can NLS just fine but races from a dig are bitches. 1st gear is the enemy. Maybe ill get out there and start launchin in 2nd

 

yeah im used to letting off the gas when shifting and frankly it just seems a little weird keeping your foot full throttle and only moving your clutch foot lol and not taking the other off the gas. I prefer to not use the NLS until i can grasp the feel for it. When the tracks open up over here i wont use the NLS until i can do it properly and efficiently.

 

I also found that 1-2 was really violent and think <fingers crossed> I have it figured out.

issue 1- Was shifting just a hair too early, causing an rpm spike

issue 2- being a touch over-aggressive with the clutch and shifter. Resolved that one by shifting a little slower. Used a full, positive pump of the clutch for timing rather than the "clutch flick" I've done in other cars. Seemed to help quite a bit.

issue 3- It always sounded like this was the biggest problem... WHEELHOP. Those "shotgun-sounding-violent" shifts always caused a nasty bounce in the seat of the pants/steering wheel and were usually preceded by some vibration/loss of grip in 1st.

I also tend to think your ability to hook up the launch properly and maintain traction through 1st gear will help settle the chassis/drivetrain for the 1-2 shift. That's my goal right now. HTH.

 

was replying to this thread from work earlier today and i decided to try NLS again today on my way home from work. (light that leads to a big, long entrance ramp to interstate). anyways, i pretty much got the same as the poster above was talking about (and what i was talking about earlier today) i shifted just a tad too early, got a slight spike in the rpms but grabbed traction fairly quickly once in 2nd ad then 2-to-3 was pretty smooth. i think its just gonna take practice. its a weird feeling cause ive never shifted like that in any of my other cars. although i do kinda like the idea of letting off from the 1-to-2 and then NLS from there on up.

 

No , but isn't that the reason GM installed NLS in the first place lol?

 

thanks to all who got back to me about the actual topic. i think its more or less normal for it to be more violent than the rest. i just wanted to make sure i wasnt the only one who was experiancing this. thanks again

 

im a newbie to cobalts. i used to have an acura rsx type s.
so i dk what you all are talking about when you say a WOT box? what the hell is that? lol

 

Ah man now the SS/TC guys are going to start crying.

 

why do people say gm designed this nls i guess people doesnt know that the mistsu evo has that feature too

 

i dont think anyone is saying they 'designed it' i think ppl just mean that they installed the feature in the car for a specific purpose and that isnt the same as powershifting a car that doesnt have the feature.

 

The way I see it is, there's two different terms that are discussed:

1) Powershifting - this is the act of shifting up a gear as fast as possible while keeping the gas pedal flat on the floor. This is nothing new - racers have been doing it for decades.

2) No-lift Shift (NLS) - this is the GM term describing the safety features built into the ECM's code that helps to protect the powertrian during a powershift - basically holding the electronic throttle body open and altering fuel delivery and spark advance to maintain RPMs instead of potentially bouncing off of the rev limiter.

/NLS discussion

To get back on topic, yes the 1-2 is violent. Personally, I prefer not to powershift the 1-2 because I've noticed the ECM pull power as a result of the violent nature of that shift. If you are going to NLS the 1-2, I think the solution might be to not be so aggressive with the clutch pedal - be smoother like when you launch the car. That's my $0.02 at least...

 

WOT box is basically an aftermarket way to get your car to No lift shift. It also works launch control so when activated in 1st with your foot on the clutch, you floor the gas and your car will only rev to like 3k (or whatever you set it at) then you just release the clutch. Then it also does the NLS feature where it advances spark timing or whatever was said above just like GM put on the SS/TC. Its been around alittle while

 

agreed.
but still, as far as the OP is concerned, when he is asking about the 1-to-2 shift on the SS/tc NLS, that doesnt mean ppl who are powershifting a car that isnt a 08+ are really offering any useful info because their car reacts differently. so therefore, no need to respond and start all this needless commotion. just my .02

 

I really don't think GM was trying to protect the powertrain with NLS. They are still hard on the car no matter who is controlling the throttle.

It's clearly a performance enhancer not a safety feature.

 

I sense jealousy!? Thats just IMO....

I guess I'd be mad if i payed the same for a car thats slower stock than the TC is.

 

Why do you have an SS/SC in your sig??? or is it someone else's that you cut and pasted?

 

i cut and pasted! What try to call me out online, Ohh no im sooooo embaressed now.

 

well its def a performance enhancer because it keeps the boost up, like you said. but its also a safety too, in that you can safely grab the next gear w/o bouncing the limiter and 'jamming' into the next gear.

 

I could give a ****.
