firehawk2003 04-30-2009, 11:47 PM I am so surprised no one has asked about the no lift shift or someone post a video of it in action we need one !!!!! I say this only because this was one of the reasons for me wanting to later on order my car manual. I wont change it if it does not have it but I think it would help for those first time manual driving folks!

I definitely wouldn't say it's for first time manual driving folks.
And I thought the whole point of "No lift shift" is to maintain turbo boost--keep it spooled--but not hit the rev limiter when manually switching gears. I've only heard of it on the LNF turbo cars, specifically the Cobalt SS.
I guess if you were to put "no lift shift" in the Camaro it would just save the transmission from excessive wear when powershifting. Can anyone confirm this as an option? Is it in any of GM's other cars like the CTS-V?
firehawk2003 05-01-2009, 01:06 AM As I recall it was on the Camaro and alot of people didnt really post anything on it which is why I ask. I just wonder what its like in action on a Camaro.
MetalDragon 05-01-2009, 05:43 PM According to the "getting to know..." booklet that was posted a while back, launch control only works when the stability control is in competition mode, the car is stopped, and it's in first gear......I wouldn't recommend running it up to redline in first then shoving the clutch to the floor without letting off the gas.
Ray86IROC 05-01-2009, 07:17 PM I wonder if the no-lift-shift function even made it into the production car. I haven't heard or seen it mentioned in writing in an official document or publication. Anyone have any info on it?
Most all the magazine reviews made mention of the launch control but I don't think a single mention was made of the no-lift-shift feature...

...I called into the podcast asking about the no lift shift after Chris and Jason test drove F-bod's car....the call got me a free Camaro z28 die cast but neither Chris nor Jason could answer if it made it to production and what they though about it...
skorpion317 05-01-2009, 10:59 PM I'm pretty sure that only the Cobalt SS has the no-lift shift feature.
firehawk2003 05-02-2009, 12:21 AM well someone that has the car needs to check this out and let us in if it does or does not !!! BUST OUT THOSE OWNERS MANUAL!
poSSum 05-02-2009, 12:37 AM Isn't that what we call "power shifting"? Why do we want more nanny than the rev-limiter for that? :confused:

Um why not? That is how 99% of us manual guys drive at the track.

Ummm...good point.

:yes:
I was also under the impression that "no lift shift" was only in turbo cars to keep the boost up between shifts, otherwise, you can do it on your own in a N/A car.

Here's how it will work in the 'vette. Expect the same for Camaro.

AdioSS 05-03-2009, 01:32 PM that's a cool video! thanks for posting that :D
It's good to know that using Launch Control won't void your warranty ;) :lol:
firehawk2003 05-03-2009, 02:14 PM can anyone post a video to confirm this!?
skorpion317 05-03-2009, 05:02 PM I think some people are confusing launch control and no-lift shift.
The Cobalt SS has no-lift shift. It allows the driver to shift gears without letting off the gas during acceleration. It's intended to keep the turbo spooled up.
The Camaro SS and Corvette have launch control, which allows the driver to floor the gas pedal and sidestep the clutch without having the rear tires go up in smoke.

This is what I'm thinking as well.
The Cobalt SS has BOTH launch control AND no lift shift. To activate launch control you have to be at a stand still, and press the traction control button once. Then you're able to hold both the clutch and the gas to the floor, and the revs will stay at an 'ideal' level (I think 5k...I should know this but I never do it in my car), then you can quickly let off the clutch and the traction control will eliminate most of the wheelspin (note, you can't just sidestep the clutch, you still have to let off somewhat reasonably). The whole idea behind this is you can mash the gas with the clutch in, get your boost built up, and then launch at full boost (for turbo cars), and of course, eliminate much of the wheelspin and still leave quickly from the standstill.
The no lift shift feature isn't actuated with a button like the launch control, it's just built in to the engine controls. In the Cobalt SS's case, it's again very useful for maintaining boost. When you go to shift, you DON'T lift your foot off the gas pedal, you keep it mashed to the floor. At the same time you stab the clutch, get into the next gear ASAP, and let the clutch out. Your right foot never moved off the gas. This keeps the turbo spooled, while the engine is prevented from over-revving by cutting fuel or spark (not sure which...or if it's both). It feels wildly un-natural for me to shift this way, and if you do it successfully you hear a single "POP" out of the tailpipe. If you stay on the clutch too long you'll hear several pops, which indicates that the engine is being limited by the computer controls.
Maybe the Camaro has this no lift shift feature, but I don't think it would be as beneficial to NA engines as it is for turbo engines....The launch control, on the other hand, is pretty beneficial since it can prevent wheel spin.
That being said, I think I have better feel for launching the car without launch control than with it. Most likely I haven't given it a fair chance, but the couple of times I tried it the car seemed to bog down too much. As for shifting, I've probably no lift shifted less than 10 times in the 8 months I've owned the car, and I don't think any of them were higher than the 1-2 shift.

How are you building boost when the clutch is in? The engine isn't under a load, so it isn't doing any work, so it doesn't need as much air and fuel, so it doesn't build boost.
MetalDragon 05-04-2009, 03:56 PM By keeping the turbo spooled from exhaust gas, it's a more instantaneous benefit when you do launch. I think the launch control feature is going to be great for A: initially learning the car and, B: launching in less than perfect road conditions. It'll be interesting to see how it does on wet pavement. From what I hear, everyone says they can get better times manually but, like I said, it could be a very helpful tool to use as a starting point for learning the sweet spot for launching the car. Kind of speed up the learning curve for us average people.

Yes thanks for posting that. I knew the ins and outs of the launch control but Tadge made a great presentation. Nice to see the graphs and show whats really going on during launch.
Nice shot on Nissan at the end too. :lol:
