Definitely and lot of reading and understanding to accomplish but Good God I was just asking a question and never had the intention of actually performing a Launch on my new C8 with 50 miles on it, just wanted to make sure it is there when the time comes. Somewhere in the past and possibly it was just speculation, I had read that for the 2023 models GM was going to limit the Launch Mode exclusively to the Z06, guess that's not the case but when I got the response Launch Not Available I couldn't help but think maybe that was true but apparently it's not. You guys come up with good information and I appreciate your help and sharing your knowledge. Thanks

I've never seen anyone report the message "Launch mode not available," so that seems to be new for 2023. If GM modified the software to display a warning, it seems likely they modified it to prevent abuse.
"Custom" launch control is supposedly Z06 only. '23 Stingrays retain the typical launch control. AFAIK, custom allows you to adjust the RPMs it holds before launch. Not a feature I'll miss...
Hi there i am new to this forum and found your post and i too am having a launch control issue. I have 2023 1LT C8 with a Z51package. I have just over 1560 miles and when I try the launch mode it says "launch control unavailable". I have read the manuals, seen the You tube videos and gone to ron fellows and actually launched a C8 so I know how to do it. The problem I am having is my C8 does not have the proper options and I am concerned about what the car may not have been equipped with. I paid for the Z 51 package so says my invoice. I am able to turn off Traction control and then I enter track or sport mode, and then press Z mode once -but it does not allow me to stay in Z mode when i push Z button a second time [ like I learned to do at ron fellows] it takes me out of Z mode when I push the Z button the second time. I also do not see any PTM options when I go to customize my Z mode. it is just not listed on the screen, is anyone having this problem? i thought it was just an issue cuz i was not at 1500 miles but i recently hit that and now i can't launch still . please help if you have any suggestions. i will be reaching out to dealer as well thanks

Updated for clarity.
As far as I know, PTM is another OPTION you have to pay for above the base Z51 package.
I selected these options:
Z51 (cooling, brakes, sway bar, spoiler, eLSD, half shafts, final drive ratio)
PTM+MSRC (FE4)
PDR
FEL

I think your confused. PTM is not an option you can chose.
When you have a Z51 and order the magnetic suspension, you get PTM as part of the package. PTM itself is not an option that you order.
You aren't tracking... What I am saying is that:
1) You don't get PTM with the base Z51 package. The OP clearly thinks or thought that Z51 comes with PTM. It does not.
2) You need to order the FE4 package which is basically an add-on to Z51 that adds MSRC and PTM. It's an option that you pay for in addition to the base Z51 performance package, that is why it is on the build sheet with an extra option code and price.
I went back and update my original post for clarity.
To get PTM, you need eLSD, and to get eLSD you need the base Z51 package, so essentially if you want PTM you need Z51+(MSRC&PTM) which is the FE4 suspension setup.

It clearly states that PTM is a separate additional option you have to order.
You are reading it wrong. It does NOT clearly state that PTM is an option you have to order. Magnetic Ride Control is the option you can order (which includes PTM). Note there is no price associated with the line item for PTM.

Re-read post #24.
He clearly thinks that the Z51 package comes with PTM. It does not.
You have to pay for the FE4 suspension which is an additional OPTION above the base Z51 package.
Some people are so ******* dense. YES, it is also MSRC. Regardless, it is NOT part of the Z51 base package. NO you can't order PTM without MSRC.
You CAN order MSRC without Z51 though. This is called the FE2 suspension, and you get a base level car with MSRC added on, but because there is no eLSD, you get NO PTM with the FE2.
I think chevy could have cleared up some confusion here with a simple table that shows each suspension FE1 through FE4 (Non Z06 Stingray) and each feature that is included.
I don't think I ever saw this clearly stated on the configurator tool, but I did see it posted in the forums somewhere.
Above your drive mode selection wheel, you should have 3 buttons. One is for PTM. If it is blank, and no PTM there, then you don't have the MSRC+PTM option.
Also, if you have a coupe, pop the trunk hatch and look at the top of your strut towers. If you have a cable there sticking out, and the side of your brake calipers say "Z51", then you should have MSRC+PTM.
If your calipers say Z51 and there is only a cap on top of the strut with no wire, then you have the base Z51 FE3 suspension. FE4 is needed for PTM.
Thx tsigwing and Dohabandit you are both right in what you have told me. For the others so you know when ordering The PTM is an extra option that comes along with the MSRC UPGRADE and is in addition to the Z51 package and that is what is needed to get launch control when setting up the Z mode and accessing the PTM options (track or sport to launch). Thanks guys!

However, according to the Owners Manual, you do not require PTM to enable Launch Control. You should be able to enable Competitive Driving Mode as explained on page 214 of the manual. And according to the instructions on page 216 of the manual, you should be able to execute Launch Control from Competitive Driving Mode. " Launch Control is a feature available within Competitive Driving Mode or PTM on all vehicles....."
That's correct. EVERY C8 vehicle can enter competitive driving mode and perform launch control. PTM is not required for that. You just need to have the correct conditions, and it has probably been said before you need to PUSH the brake to the floor with full force.
Once your RPM hits the 3500 launch number, I wouldn't wait too long before releasing the brake. It seems to me that the clutch paper may be wearing at this time because once you hit the gas the torque building in the drive train is apparent.
There aren't too many good videos that demonstrate the difference in handling of the C8 with or without PTM, but a while back I saw one produced where they had a large parking lot (empty car dealer lot) where they setup a course and showed how the vehicle handled with and without PTM enabled.
It's the only video I have seen where you could visually see a difference in how the vehicle handled around turns with PTM equipped and enabled.
