Ok watched your video a few times. The problem is you are launching too aggressively for the conditions. (tire pressure, surface prep, temp etc) With the TC off you are just spinning the tires, and with TC on the car is compensating for the wheel spin by pulling back throttle. (that’s the bog you are feeling) Try a lower RPM, probably 3-4k and don’t sidestep the clutch.
I also noticed from watching the video that you are very aggressively over driving the car. When you are in one of the PTM modes you have the TC light lighting up constantly (16 times a lap average) especially when applying throttle in turns and the car is reducing throttle to keep you from spinning out. When you turned the TC off you felt like the car was impossible to control because you are developing bad habits that the TC is covering up for you. The laps you ran with the TC fully off is how all of the other laps would have been if you hadn’t had the nannies intervening to keep the car under control. Since you are auto crossing, and it is a relatively safe environment I HIGHLY recommend you turn off as much of the TC/PTM systems that you can and learn to drive without their intervention. Otherwise you run the risk of reinforcing bad habits and relying on the TC to cover for you.
Also DO NOT shift to 1st gear unless you are forced to drive an element at under 15 mph. The time you waste shifting can rarely ever be made up for in the additional acceleration from 1st, and the car becomes harder to control due to the extra torque in 1st gear. If you had the nannies off on those finishes where you shifted to first you probably would have taken out the timing lights on both runs. Your course designer set up the finishes that way to keep people from going too fast though the timing lights, ask me how I know this.
Here are the runs I had from this weekend at our event at the Michelin Proving Grounds, Blacklake in Laurens SC. There are two videos because my Gopro died on my 4th and fastest run so I had to pull that off my dash cam so no sound. There are no overlays to show throttle/rpm and speed but hopefully you can see how I have the car under control the entire time despite having the TC completely off. The exception is the first run where for whatever reason even after 3 course walks I forgot how sharp the first turn was going to be with wet pavement and over drove into the first slalom, I also had some issues on the back sweeper which I fixed for the most part on the following runs.
Maybe if
mjk3888 is willing he can post his PDR videos from the same event for comparison. Sorry to put you on the spot bud but I think
tx6g1le will find it helpful since you both have the same car.
