Let's be patient. I have faith the GM engineers are going to take care of the '17 owners. I will get the Control Tec installed on my car as soon as it's made available. We'll get the data and be on our way to getting a software update.

So it looks like this issue was identified and that's probably why the folks you spoke with said they may know what it is and just need to confirm. Interesting!

Hopefully we can get some feedback from 2018 owners soon...

Is this birdie associated with GM by chance? Reason I ask is bc if you watch lethal camaro's 1le ride video, that car seemed to fall down using launch control too. At least it seemed to do what mine does using launch control.

But it's awesome that they'll look into it and hopefully offer a fix to get these cars moving quicker

I was watching the eLSD system today and it's definitely acting funny. I can be at a light and just rev the car in neutral and it'll read 7%. Just driving down the road and giving it any gas will make the value increase %, without the wheels anywhere near breaking loose.

They didn't dyno your car correctly. I received the same reading because they didn't go to 4th gear. Tell them not to do it in 3rd, it's a 6 spd.

Glad I'm not the only one experiencing this. Rolling starts is the only way I race. Track racing sucks because of the 1st gear bog. But I met a guy that has a Vette and he experienced the same issue. He said make the trip to his shop and his tune will fix the issue. I plan on going next month...will update when I get it done. Here is his website

Here he is destroying a Hellcat


Here he is beating a 1,400 horsepower All Wheel Drive Jeep

Does this apply to 1LEs? It is trying to launch this car hard... Try all settings... Similar experiences.

Just picked up my M6 last night. Drove it 750 miles back home. I had zero issues. I have been driving manual trans cars since I was 9, learned on my grandfathers 67 Chevy pick up with a 3 on the tree.

I could just either let the clutch out slowly and it would roll away from the light or rev lightly and engage. Either worked fine.

Of course with only 750 miles I have not tried to "launch" it so the jury is still out there.

I didn't have time to read all 12 pages, but this issue that the OP has in the video is the same thing I am getting in my 2018 manual trans Z06.

The other issue I have with eLSD is its not locking as much or as quickly when it gets hot. I get one tire spinning a lot in corners. Is that happening to any of you and is it related?

[Timbo-1LE]

Again 1L SS and also experience this bogging

In addition, probably NOT related, but my elsd % the past day has hit high of 49% in sport with heavy throttle getting on freeway.
Prior, never saw higher higher than 25. Only difference, just turned over 75 engine hours. I know it has been stated there is no mileage based safequards, but weird....

[JayhawkSS1LE]

My SS 1LE experiences this same bogging on launch. I am in Track Mode and in Sport 2 and it just spins for a half a second and then bogs down... makes me feel like a moron lol

Makes me wonder how I would be able to just light up the tires if I so chose to do so...

I would also make sure they turn off all the nannies.

Did not read all 18 pages of posts but I have had 2 cars which had traction control o them.
A 550 Maranello Ferrari. Every time I nailed it either from a stop or in lower gear and broke the tires loos and the traction control was on, the engine would cut out and then come back on. it was like horrible. I learned to never drive with any computer controls on in the car.
Now I have a ZL1 1LE and brought it home yesterday and again first thing I did with the dealer was inactivate all the computer over rides for traction control and stabiltrac.
I rely on my foot and feeling as to what to do and have not even looked at launch control. I am a road racer though so I just want it all off.
So far though clutch engages fine and positively and then after when I nail it it goes. No lag.

You mean the dealer went into the computer and overwrote the TC and Stabilitrac completely?

Seems like that would be a huge liability if it were even possible. I could be wrong, but I really question GM even giving Technicians the ability to do something like that.

Me too.
