Ah thank you for that! However, I cannot replicate what the video of the ZL1 does nor that sound. Does anyone have a video of this in their c7? I have a c7 z06 but I would think the ecm would be the same for this function.

Higgs is right on. I had a ZL1 prior to the Vette. Used the NLS a number of times. It works great. Hard part is fighting the impulse to lift your foot off the gas - force of habit. But once you get the hang of it it is a great feature.In the ZL1, the HUD had 2 lines with a LED that moved towards each other, when they turned red, you were in the range for using the NLS.
I haven't run the Vette yet to try it, but when I did Ron Fellows 2 months ago, they discussed it and said the Z51 definitely has the feature. They weren't sure about the non-Z51.

It is all a feature of launch control just like the BMWs and Porsches that have DCTs. Activate launch control, put the throttle to the floor and the system will keep the engine from overrevving. Let the clutch out and leave the throttle on the floor and shift when you get to the shift point. Don't take the throttle off the floor or the car drops out of launch control. There are plenty of videos showing C6 drivers doing this.

I have run the car with both no lift shift on and off via hp tuners and to he honest it works perfect. Originally thought it was pulling timing but it works just as planned and holds the rpms with a nice backfire between shifts. Here is a video of me using it the other day during some testing:

I want to be sure before I try it.

Ok then as I understand you all the 7 speed manual cars have the feature and there are no particular presets other than traction control off for 1/4 mile drag fun and in the track mode versus touring or sport?

I tried the no lift shift last week. As already mentioned, you have to try to turn off your muscle memory to avoid lifting off the gas. Not too hard though. Not sure if I'd choke at the drag strip or not. It's pretty slick. I'm sure I'll get hell for this, but with nls I think it's possible to shift this car fast enough to rival an A8. Like 10th of a second fast. Close enough you wouldn't be able to tell the difference on an audio recording unless you were counting shifts. Of course the M7 is still at a disadvantage finessing the car off the line compared to the auto, but you should at least be able to compete with an A8 in a roll race. No lift shift is great with a drive by wire as the delayed reaction to your throttle inputs has to slow shifts down. Things are happening fast when you speed shift, and the dbw probably has a .05 second delay. After all, you can floor the C7 and let off quick enough that the ecm doesn't even react. I can't do that in my cable throttle body GTOs.

I really need to try this again. I want to believing everyone but I swear my c7 z06 does not have this feature. Every time I tried I almost crapped my pants because the rpms shot way up and the tires broke loose so badly .
Is nls engaged throughout the rpm band or is it not engaged till after 5k?

yes as long as you perform the movement correctly. basically floor it, leave it there and clutch/shift quickly, if you shift to slowly it will revert to a normal throttle closing rev limiter.
