Lololol, that's a fantastic analogy
but yeah that's the downside of the car trying to protect itself; it can sometimes be over-protective and stop you from doing what you want it to do even if what you're doing won't necessarily be damaging.

I also haven't been able to figure out the way the launch control reduces torque. In the logs it appears as a "RPM Limiter" which kind of indicates it is a function of the ECM and similar to how it reduces torque at the rev limiter. However, there is still something requesting a torque reduction but it appears to be a predicted source only (predicted means it uses the throttle blade to control torque, immediate means it uses timing).
If we could understand all these parameters and had access to change the CCM calibration I think we could use the launch control and traction control to our advantage. The stock launch control, especially when you have mods, just seems to bog the engine way too much. With my cam, ported heads, intake, and TB the stock launch control kind of works but it will start bucking real bad as it seems like the ECM gets unstable trying to control it, then once you take off it bogs really bad so its basically slower than when I had stock heads and stock cam.

Some of the MY19 Camaros have custom launch control which gives you a bit more control over all that stuff. Unfortunately it's not a nice plug-and-play solution for the 16-18 cars. Have to get updated and/or custom software made for a few different modules to get it to work, and I'm at least not aware of any aftermarket solutions for that yet :( Just stuck with the generic solution that gets you in the ballpark so it's better than nothing, but it isn't optimized for anything.
