Looks like you need R-compounds and less aggression with the throttle on mid corner.
I applaud you for Auto-X’ing this car, probably the worst case scenario for these heavy torque monsters.

Can you tell me more about your setup? I see the original wheels, what tires are you running?
Ive AutoX'd my C63S also and was only able to get decent traction by being light on the throttle and doing a little burnout to heat up the rears. I run PS4S tires.
With the start to that track being a direct left turn i assume throttle control is going to be your best friend.

I could get R-Comps, but that'd mean getting another set of wheels and that puts me out of class.

I've also come to realize driving the C63 would require a more delicate control than the Camaro 1LEs, this car is overweight and under-tired. I might try 315/30-18 in the rears when the rears worn out.
I tried the car out with TC first but with it On, and Sport, it just intervenes too much. I tried all 3 in my first event, but my times were pretty close. I think the trick is to slightly under-drive the car a bit. Maybe Race mode in the S-es help.
At least the gearing is great for Auto-X, so we've got that going for us.

A couple of thoughts. The sedan is definitely under-tired, and doesn't have a reworked rear axle like the coupe with a wider track. Since you have the non-S, you also don't have the electronic locking differential, which makes a difference especially for Auto X and track driving. Since you have a 2016 you are also limited to TC on, sport or off and that's it. You don't have the new AMG DYNAMICS system. The 2019+ S models have the 9-stage traction control straight from the GT3 so one can dial in just enough intervention to get around the course w/o going sideways constantly, but also not being bogged down completely. You would have 9 levels to dial it in precisely and could even adjust from corner to corner.

Yeah, the mechanical LSD primarily avoids the infamous one wheel spin, but it needs one wheel to have a certain amount of slip before the locking mechanism does anything. The e-diff constantly monitors many sensors such as steering angle, acceleration, cornering forces, perceived amount of traction etc. and precisely calculates how much to lock and how much torque to send to each rear wheel which is known as torque vectoring.
