The rear rotors were about 350C and the rear calipers at 96C were a bit warmer than I got them to at PECLA. I was more comfortable in the car at this point. Granted, I was using different tools for temperature measurement, so there’s some uncertainty introduced.
I modified my driving style which seemed to work in getting the tires more even in temperature front to rear. The temperature split was less than 10C compared to the 28C I experienced at PECLA. Basically, I late apexed the corners more which meant scrubbing off more speed in the braking zone, getting the car turned quickly, straightening out the wheel, and putting the hammer down. I was definitely driving in a more point and shoot style.
I set the tire pressures to 2.4 bar the night before going to the track. As also shown by the tire temperatures, the front tires are at a bit higher pressure than the rears. Another observation is the dynamic range estimator which is showing 68 miles left with half a tank of gas. I was averaging about 10 mpg on track which is better than I thought it would do. The stock tune does run an air:fuel ratio of lambda = 1.0 through much of the engine operating range. Back to the dynamic range estimator, it shows a warning to refuel when the range drops below 50 miles which was at around a third of a tank left. That’s annoying because I lost the temperature gauges.
With only 300hp, 55% of the weight on the rear due to the mid-engine layout, 265 wide rear tires, and limited slip differential, the T puts down the power very well powering out of turns. I could feel the LSD doing its thing with the rear tires clawing for traction. This is my first track car with traction control and I used the PSM Sport setting which gives a bit more freedom to get loose. I honestly never got anywhere near those limits and I would typically drive with traction and stability control off, but I really like the auto rev matching of the downshifts for track use. I just mash the brake, shift the gears, and push the clutch in and out. On the street, I do turn PSM all the way off and do my own rev matching. In other observations, the T is the first car I’ve felt the need to get driving gloves due to the Race Tex material on the steering wheel. My skin tends to be pretty dry out here in the desert, so the steering wheel is too slippery otherwise. Oh, one other thing, the wind buffeting gets pretty bad at 100mph with the windows down.

Using the Launch X431, it’s hidden somewhere under Porsche Stability Management which I think is under DCM. I had to actually use the search bar using the term ‘PTV’ to find it.
