What mode are you in? I was in track. I’ll try again tomorrow in Sport....My car definitely doesn’t do this.

I will, was busy getting to a track event this weekend... I'll get 1 posted today. It does work..

Here is another example up a steep incline..

pbsinternet: Well dang no wonder - you've got a cammed motor and the tuner set the idle tables above stock idle. You're idling at a much higher rpm when you start so your motor keeps that higher idle as you walk the clutch out.

My cammed LS3 gen 5 would do the same thing. It was tuned by Mike at Vengeance as well.

I tried this several times on my stock LT1 and it pulls away with no drama just like yours except it does it at stock idle speed - 500-600 rpm.

It won't stall as the computer won't let it. Nothing to do with idle speed or cam.

I’m still struggling to understand why this so unique. I’ve owned 9 different manual transmission cars from a 66 VW bug to my 2016 SS. I could launch every one of them from a dead stop by slowly letting out the clutch and not touching the gas. Yours just happens to do it at 900-1000 rpm because that is what your idle speed is set at. The amount of torque we have with our LT1 motors certainly makes this easier and fun.

You car sounds awesome! I do miss the cam thumping of my old LS3.

It is not torque or the cam. I actually learned about the clutch slip programming from a tuner because with a cam the computer detects slip much more and closes the tb causing a stall. It is unique from what I was told no other car has this feature. If you rev too high and slip the clutch it will close the throttle body and possibly stall. If you let the clutch out normally and do not touch the throttle it will maintain rpm and roll away clean. Computer is maintaining engine speed. Stall is much worse with a stage 3 cam. This programming allows you to leave a stop.. zero throttle on any hill.

On a stock SS (or any model), the controls will try to maintain the normal idle speed, but you could definitely stall. There’s no unique idle speed that I can see present when you release the clutch pedal with no throttle. This is something all cars do and would depend on the calibration and power available at those speeds to determine how robust they are at starting off with no throttle. If your normal idle is set to 900-1000 as it appears in the video, there’s a lot more power at that engine speed than ~600rpm on a stock car.

On my stock ‘17 SS I would do 0% throttle ‘take-offs’ all the time to inch forward to the starting line at the drag strip. Engine speed never tried to maintain 1000rpm as I released the clutch pedal.

Not at all what I'm talking about.

Can you please stop? At this point you are just spreading misinformation

[Tankk]

The no lift shift is a supported feature for track/drag use that AFAIK doesn't hurt the clutch at all, so I guess that aspect of little wear isn't surprising.

[Xaxas]

LOL, the ease slip off the clutch is not a feature but the nature of manuals, it's just that the 1LE has an amazing clutch and so much torque that it makes it easy, I did this when I was learning to drive in my 2007 Fiat Palio R with 1/4 the torque the Camaro has

[eimarshall]

My highschool honda accord did the same thing. as well as my BRZ, and my 240SX, and my tacoma........ slipping the clutch, will allow a throttle-less take off. You just have to go slow. with a higher torque motor, it is easier, but its not like its impossible in anything else.
