Right, the videos I made were to show what the NLS function in our cars is doing behind the scenes but when trying to shift fast it mostly just prevents the RPMs from rising and hitting the limited with no load. NLS in this car is very different from no lift shifting any other car since it is actually a software function rather than just shifting quickly and hoping you don't hit the limiter.

Any chance you could perform a follow-up test, specifically with Rev Match off to determine if the NLS engine speed is held differently than shown in your videos?

I have a 1SS (non-1LE) and ran this same test tonight in Track Mode with Stabilitrak Competitive Mode enabled as well as Active Rev Matching enabled (in case that matters). In 1st gear I go to about 6300rpm, clutch in, shift to 2nd, while keeping the accelerator pedal at 100% the whole time... I intentionally kept the clutch pedal down so I can see the feature in action. Mine just bangs into a rev limiter at 6500rpm, so I don't think No Lift Shift is working properly.

Can someone else with a non-1LE SS repeat this procedure to see if theirs behaves similarly? What could I possibly be doing wrong that would cause the feature to not work?

Mine appears to be working the same way as gippy87's car ('16 2SS).

Just do no-lift shifting with the rev limiter. Set the control method to spark or fuel (whichever you prefer) but disable ETC. Set the switchover delay to 20 (the entire table), then set the cutoff RPM vs gear wherever you want it. The numbers you put in Park and Neutral should be the same, and the computer will hold them when you have your foot on the clutch pedal, when you're off the clutch pedal, it'll rev to the numbers in the rest of the table.

The way I do it, I set my in gear numbers to 7200 RPM, and my park neutral to 6000...when I shift, the PCM cuts spark (to the numbers in the minimum final spark table I believe) but the throttle plate stays open. This seems to help abuse the transmission less, and it returns to life instantly when my foot comes off the clutch pedal. You can set the same RPM too...but I found if shift at 7K, I want the tach right around 6K anyways.

Based on the info above it seems the Park and Neutral rev limit settings are the ones also used for NLS. So if you were in neutral (or in gear with the clutch depressed) the engine would only rev to 5500(?) RPM instead of 6500 RPM. Anybody should be able to test this in neutral as well as while using NLS?

I took a video a few minutes ago of my 17 1SS (non-1LE) attempting NLS. The video doesn't illustrate how violent the shift is, but you can see how the RPMs do not drop at all until I release the clutch. It bounces off of the rev limiter even.

Weird, definitely does not look like your car has NLS active.
Did you have rev matching on or off?

On. You can see the gear indicator is orange.

So we both have 2017 1SS's, only difference is mine is a 1LE. Seems like there are other non 1LE cars that do have NLS active. So some cars randomly do not have this feature activated while others do?

doesn't look like competition mode on and traction control off in adamizme video.. i thought those were needed for NLS to work?

Not for me, I use NLS in Sport mode traction on all the time.

Mine does the same regardless traction on/off, TOUR, SPORT, TRACK, competitive mode, have tried everything. I gave up before screwing up the car.

I drove a automatic 5th gen before, so holding down the pedal all the way to the floor was never a problem for me.

But I really think that the non-1LE doesn't have NLS.

2017 1SS bought in December 2016.

Clearly some camaros have it but i think a large amount of people that dont understand nls are thinking they have it. They come here and read camaros have it and then proceed to go out and successfully shift to the next gear while not lifting. As its already been stated by some in here if you shift fast enough the rpms wont bounce of the rev limiter while not lifting but that can be said for any car with or without nls. Based off what I've read in this thread there are many that have been shifting this way thinking they have nls.

What is interesting is that both Motor Trend and Car and Driver specifically mentioned that they use the No Lift Shift algorithm on non-1LE SS cars. Al O. also mentioned at the Camaro Fest 7 in Bowling Green that the feature exists on the SS (although I didn't probe further to confirm he was talking about the non-1LE SS).

I wonder if there's something goofy in the software where only cars with MRC got the No Lift Shift feature enabled (or something similar to that).

Could be a calibration mistake that only made it out for certain configurations of the non-1LE SS.

[gippy87]

Until someone can post some video proof of non 1le's having it its hard to say what options the cars with nls have. I have a 2ss with mrc and all other goodies but no NLS so really unless it was just completely random at the factory it doesnt seem like options matter.
