Will the no lift shifting feature work in Touring mode with all nannies on,
this is the only mode I can get a decent launches with, best 0 to 60 on a prepped track in Track/race is 4.0, the car bogged badly in touring leaving exactly the same way (but having to pedal a bit no bog at all) on the street
3.7, just want to make sure the no lift shift feature will work in Touring before I try it

I think so, but if you want it answered straight from the engineering team, vote for that question in the "ask Al" subforum:

Just shift fast and you'll be alright.

I would think it should work no matter the mode. I'd test it by trying a no-lift around 5500 rpm, so there's no worries if it doesn't work. Even at a higher RPM, a good fast shift will prevent any issues, if no-lift doesn't work.

Are the cars designed for this?

It should be active no matter what mode you're in (I'd probably stay in Sport to be on the safe side)

In 5th ZL1s and C6 ZR1s its active all the time, just make sure you rev it out, stab the clutch, yank the gear, and get off the clutch as fast as you can. NO granny shifting. Note: If you push the clutch in well below redline (AKA 5500 RPM) the RPM will flare damn near instantly to true redline, 6500 RPM I believe, and it could be scary. Don't forget, NLS is going to let the car rev to redline, not hold at the RPM you pushed the clutch at. Make sure you have the throttle wide open while you're doing it or it will cancel the function and you'll bang painfully off the limiter.

Can't stress enough that this is not a feature to use just because, and again, NO granny shifting. If you're NLSing, you're going to max performance and you'd better be shifting good. If you don't execute the shift rapidly, the car will cancel it and you'll watch the RPM hold for fractions of a second before it just lets hit the limiter until you let off.

I would NOT try it at 5500 either, or the RPM's will "whip lash" in a way. If you try it you'll see what I mean. Rev it to 6200-6500 and stab the clutch, yank the gear, and get off the clutch as fast as you can. Make sure you're paying attention and your shift is executed in half a second or less. (I say this not because that's how long it will hold RPM, it will hold it longer, but you want to aim at shifting in that period of time).

Watch this video:

It's a Viper but the same theory. You need to AIM at shifting like that, even if you are slower.

Yes. This and much more. It's gentler on the car than traditional manual power shifting.

No Lift Shifting works in any drive mode, with/without rev match on, with/without traction/stability control on. The only requirements for NLS: 100% Wide open throttle, rpm’s over 5,000.

i don't understand the distinction you make between car "holding rpm at redline" vs "bang painfully off the limiter" pls explain.

how is "NLS is going to let the car rev to redline" different than what any car would do if you push the clutch in while gas pedal mashed? (i.e. hit the rev limiter)

I would expect NLS to manage RPM in some fashion OTHER than simply allowing rpm to rise to redline.... not much of a feature there.

NLS cuts timing to the motor, resulting in RPM’s stalling/falling slightly when the conditions for NLS are satisfied. 100% WOT and RPM @ 5,000+.

If those conditions are not satisfied, the engine will rev just like any other manual without NLS. Most common issue is that guys don’t hold WOT, if the gas is at 95% throttle, the car will keep reving, just like any other car without NLS. Hold throttle at 100% and NLS works.

you describe NLS with "RPM's stalling/falling slightly" which IS what I'd expect.... but quite different than other guys description above that RPM's will immediately rise to redline... and we have videos of both scenarios.

It seems to work like you describe if you have a 1LE while us folks with SS just get the RPM's rising to redline.

I haven't seen any proof otherwise, no wonder this topic stays alive.

just to be clear, nobody is saying you need NLS to shift without lifting (i.e. power shifting) that can be done in any car.

but NLS should do SOMETHING different than allowing rpm to shoot up to redline.

Ok, this is a full session at the National Corvette Museum MSP. I posted the full session so you can see when I’m using NLS and when I’m not. Anytime you see the gas stay 100% green and a shift occur= NLS. On my outlap I never use NLS, but at 2:05 you can hear the NLS timing cut very clearly as I’m next to a concrete wall for the 3-4 shift on the straight. It sounds CRAZY inside and outside the car. Pretty sure all SS-ZL1’s have NLS.

Holding at Redline and banging off the Rev limiter are two very different things...

If you execute a NLS properly at 5500 RPM, you'll notice the RPM will immediately jump to 6500 or so as soon as the clutch is pushed in, but it will not bang off the rev limiter.

I don't know what Provoste means by "Stalling/falling" unless he's talking about AFTER the clutch has been released which is true.

I'll attempt to write an example of what the RPM does vs position of the shift:
full throttle, 2nd gear, 6000 RPM
Clutch is pushed in (Throttle is still 100%)
RPM immediately goes to 6500 RPM (Or whatever your redline is set to in the computer) and holds, simultaneously the shifter is moved to 3rd
Clutch is let out
RPM falls down to ~5200 or whatever the RPM would be for that gear at that speed as it re-engages with the transmission

IF you didn't have NLS:
Full throttle, 2nd gear, 6000 RPM
Clutch is pushed in
RPM flies up to 6500 (Or your redline) hits the limiter repeatedly, resulting in that horrid "banging" noise that we've probably all heard some body do when they're showing off their new exhaust
Gear is shifted to 3rd
Clutch is let out
RPM falls back to whatever it needs to be at to match the trans.

Maybe this video will explain it better, skip to like halfway through and use the sound of the car to picture the tach:



Best thing you can do is do it for yourself if you can't figure it out. As noted it's always active under these conditions:

"No Lift Shifting works in any drive mode, with/without rev match on, with/without traction/stability control on. The only requirements for NLS: 100% Wide open throttle, rpm’s over 5,000."

While we're on this topic...

Can anyone share their drag strip experience with NLS at 5500 or close that rpm as compared to 6500 shifts? I thought I saw somewhere where this might improve the 1/4 mile time on another members experience. TIA
