Based on the pdr footage, you lifted and I'm curious that if you made a run without lifting if it made a difference? I apologize if you answered these questions already, I just didn't see by skimming the thread.
I've noticed that with anything less that a 10% slip target and under a 3500 rpm launch on an unprepped surface, there's too much interference and the car just falls down, THEN chirps through 1st much like your car did. Did you try just maxing the parameters out (4000 rpm launch with a 15% slip target) to see what that'll net? If so, what results did you get?

I only used Launch Control for the 1st 2 runs. I listed the launch targets for RPM/wheel slip above each video in the OP. Everything after that was full manual. I only used TPM to get the line-lock so I could do a decent burn-out before each run. Then I disabled all automated controls by holding down the Stability Control button for 5-sec. before staging at the tree. I did not try feathering the clutch when using custom LC that I recall. I felt that would defeat the purpose. Manual launch with TPM engaged nearly always badly bogged the motor, resulting in horribly slow 60' and 1/4 times.
I have tried almost every conceivable combination of RPM/slip targets on previous visits to the drag strip. As I said in the initial post, it's nearly impossible to predict the combination necessary to get a perfect automated launch because traction/conditions change from one run to the next. Read the section labeled
[Auto/Custom Launch Control] again. Feel free to experiment on your own. You might have better luck than I.
